Change Log

All notable changes to this project will be documented in this file.

download(_:to:) and download(_:to:resumingFrom:) methods that create DownloadAPIRequest with <URL, ErrorModel> generic constraints to simplify requests creation, where you need only URL from resulting operation.
Structured Concurrency support for Swift 5.5 and higher: RequestSender, DownloadRequestSender types.

Fixed

Issue, that could lead to sending network request with api stubs enabled, but Session.startRequestsImmediately property was set to false.

Breaking

New deployment targets: iOS 11 / tvOS 11 / macOS 10.13 / watchOS 4 / Xcode 13. OS deployment targets now match minimum deployment targets, supported by Xcode 14.

5.4.1

Changed

Improve Combine extensions to work better with stubs, that return synchronously.

Fixed

Swift 5.4 warnings

5.4.0

Changed

RxSwift dependency bumped to 6.0 and higher

5.3.0

Added

Ability to modify URLRequests before it's adapted and sent:

tron.codable
    .request("status")
    .modifyRequest { $0.httpShouldHandleCookies = false }

This feature uses Alamofire.RequestModifier closure, that can also be set without DSL on request instance directly:

let request : APIRequest<Post,Empty> = tron.codable.request("posts")
request.requestModifier = { urlRequest in
    urlRequest.httpShouldHandleCookies = false
}

5.2.0

Added

Combine support on supported platforms through publisher() method on APIRequest, UploadAPIRequest, DownloadAPIRequest.
APIError.isCancelled property, that tells, whether request, that errored, was cancelled by sender.

Changed

Alamofire.ParameterEncoding, JSONEncoding and URLEncoding are now exposed through TRON API and don't require importing Alamofire to use.

Deprecated

NetworkActivityPlugin is deprecated on iOS 13 and higher, because UIApplication.isNetworkActivityIndicatorVisible property it has been switching is deprecated on iOS 13 and higher.

5.1.0

Changed

Several Alamofire types that are exposed through TRON API's are now implicitly exported to allow using them without needing to write import Alamofire. See Exports.swift file for a list of them.

5.0.3

Added

FileURLPassthroughResponseSerializer, which can be used as a response serializer for DownloadAPIRequest when you are only interested in URL of downloaded file.

Fixed

NetworkLoggerPlugin now correctly skips cancelled requests

5.0.2

Added DownloadAPIRequest.perform(withSuccess:failure:) method, similar to APIRequest and UploadAPIRequest methods.

5.0.1

BaseRequest.headers now default to HTTPHeaders.default to allow sending Alamofire default headers such as "Accept-Language", "Accept-Encoding", "User-Agent".

5.0.0-rc.1

Added

Better debug prints for NetworkLoggerPlugin when decoding using Codable protocol.
configure(_:) method for BaseRequest DSL to allow configuring request with several changes at once.

Breaking

Plugin API that previously was called with Alamofire.Data/DownloadResponse<Model, Error> is now called with Alamofire.Data/DownloadResponse<Model, AFError> due to Alamofire changes to error handling.
performCollectingTimeline(withCompletion:) method is now called also with AFError instead of Error.

5.0.0-beta.5

Added

Support for per-request Interceptors.
Three different behaviors for building URLs: .appendingPathComponent, .relativeToBaseURL and .custom. Those can be set in TRON initializer:

let tron = TRON(baseURL: "https://www.example.com/", buildingURL: .relativeToBaseURL)

Or you can change URLBuilder.Behavior on per-request basis, using the new DSL:

let request: APIRequest<Int,APIError> = tron.swiftyJSON
    .request("status/200")
    .buildURL(.relativeToBaseURL)

Default behavior for TRON is .appendingPathComponent.

Removed

URLBuildable protocol. Please use different behaviors for URLBuilder instead.

5.0.0-beta.4

Added

Support for Swift Package Manager in Xcode 11
New convenient DSL, that allows to convert this code:

func deleteSession() -> APIRequest<Empty, UnknownError> {
    let request : APIRequest<Empty, UnknownError> = tron.codable.request("session")
    request.method = .delete
    return request
}

into:

func deleteSession() -> APIRequest<Empty, UnknownError> {
    return tron.codable.request("session").delete()
}

Read more about other DSL improvements in 5.0 Migration Guide

Changed

URLBuilder now resolves URL's using URL(string:relativeTo:) method, thus allowing more flexible url creation.

5.0.0-beta.3

Added

Ability to traverse json to any level when using SwiftyJSONDecodable.

Changed

Improved response serializer behavior for cases where requests were stubbed using URLProtocol.
TRON 5 requires RxSwift 5 and SwiftyJSON 5
Core is now a default subspec for CocoaPods installation method. To use SwiftyJSON, add following to Podfile:

pod 'TRON/SwiftyJSON'

5.0.0-beta.2

Changed

ErrorSerializable protocol changed to have non-optional initializer and to not accept serializedObject. It no longer can be used for additional object validation, but behavior should be more predictable and straightforward - ErrorSerializable should only be created if somebody (URL loading system, Alamofire or Model serialization) actually reported error.
codable is now a lazy stored property instead of computed property.
CodableSerializer API has been made open to allow easy customization in subclasses.
NetworkLoggerPlugin now has a constructor that allows to easily configure it's behavior.

Breaking

Properties that worked with Alamofire.SessionManager have been renamed to session to be in line with Alamofire renaming of SessionManager to Session.

Removed

TRON.defaultAlamofireManager() method. TRON initializer now uses Alamofire.Session.default as a replacement.
TRON.processingQueue property

5.0.0-beta.1

TRON now requires:

Xcode 10
Swift 4 and higher
iOS/tvOS 10 and higher
watchOS 3 and higher
macOS 10.12 and higher

Added

Complete documentation
TRONDataResponseSerializer and TRONDownloadResponseSerializer structs to encapsulate serialization of responses using closure.
All test suite now uses StubbingURLProtocol to stop tests from sending network requests. Closes #21.
Additional JSONDecodable conformances have been added for arithmetic types such as Int8...Int64, UInt8...64.

Removed

EmptyResponse type was replaced with Alamofire.Empty struct to not interfere with Alamofire.EmptyResponse protocol.
TRON.stubbingShouldBeSuccessful property since now each stub directly defines it's behavior instead of global setting
Conditional conformance of Array to JSONDecodable
Convenience download methods on CodableSerializer and JSONDecodableSerializer
AuthorizationRequirement enum. Please use Alamofire.RequestAdapter and Session.adapter property to adapt request, when additional headers are needed.
HeaderBuildable protocol and HeaderBuilder types. Please use BaseRequest.headers property of type Alamofire.HTTPHeaders directly.
ErrorHandlingDataResponseSerializerProtocol and ErrorHandlingDownloadResponseSerializer protocol. Now, ErrorModel on all requests conforms to ErrorSerializable protocol, that contains initializer that allows to create it directly.
CodableDownloadParser and JSONDecodableDownloadParser, replacement class DownloadSerializer has been introduced, it allows to create a data model by implementing DownloadResponseSerializerProtocol
UploadAPIRequest.performMultipart method, because multipart upload is no longer a special case in Alamofire 5, please use UploadAPIRequest.perform instead.

Breaking

headers property of BaseRequest now contains HTTPHeaders type instead of [String: String]. Please note that along with HeaderBuilder removal TRON no longer sends 'Accept':'application/json' header by default.
APIError is changed to be able to accept SerializedObject and is now a class with nullable initializer. Also, DownloadAPIError type has been introduced for download errors, that do not have Data in them, but have fileURL instead.
Plugin methods that previously accepted APIError<ErrorModel> now accept ErrorModel directly. Added didSuccessfullyParseDownloadResponse and didReceiveDownloadResponse methods.
All concrete implementations of DataResponseSerializerProtocol such as CodableParser and JSONDecodableParser now have only one generic argument - Model and are only parsing model type.
JSONDecodableParser and CodableParser now have only one generic argument - Model, since ErrorModel is now moved to ErrorSerializable protocol, that does not depend on any particular serializer.
APIStub has been rewritten from scratch to allow injecting only results of network request(URLRequest, HTTPURLResponse, Data, Error and fileURL) as opposed to actual Model and errorModel as well as definition of successful/unsuccessful requests. APIStub now is been attached to Alamofire.Request when stubbing for this particular request has been enabled. Rewrite also allows plugin callbacks to be called more consistently for both stubbed and unstubbed cases.
rxMultipartResult method on UploadRequest method was removed since UploadRequest for multipart requests in Alamofire 5 is now synchronous and now does not require special handling. You can now call rxResult replacement method instead.

4.2.1

Fixed

UploadAPIRequest now calls didReceiveDataResponse plugin methods when sending multipart-form requests.

4.2.0

Implemented JSONDecodable support for Arrays, whose Element is JSONDecodable. Requires Swift 4.1 to work.

4.1.2

Improved output of NetworkLoggerPlugin, which now includes status codes, HTTP body contents, and some emojis 🚀

4.1.1

Allow EmptyResponse to be used with CodableParser when network response does not contain valid JSON.

4.1.0

Deprecate TRON level headerBuilder in favor of Alamofire.requestAdapter.
Loosen CodableParser generic constraints to be able to work with Decodable protocol instead of Codable.

4.0.0-beta.2

RxSwift dependency is bumped up to 4.0.0-beta.0, SwiftyJSON dependency is bumped to 4.0.0-alpha.1
Binary release is compiled with Xcode 9.0 Swift 4 compiler.
Added ability to customize JSONSerialization.ReadingOptions for JSONDecodableSerializer. Unlike previous releases, no options are specified by default(Previously SwiftyJSON used allowFragments option).

To have old behavior that allows fragmented json, use:

let request = tron.swiftyJSON(readingOptions: .allowFragments).request("path")

Added ability to customize JSONDecoder for CodableSerializer for both model parsing and error parsing.
CodableParser and JSONDecodableParser are now classes, that are subclassible.

4.0.0-beta.1

This is major release, containing breaking API changes, please read TRON 4.0 Migration Guide

Implemented support for Codable protocol.
APIError now takes it's localizedDescription from underlying errorModel if that model is LocalizedError, and from error.localizedDescription if not.

Breaking changes

SwiftyJSONDecodable methods are now prefixed with .swiftyJSON, like so:

// old
let request = tron.request("path")
// new
let request = tron.swiftyJSON.request("path")

3.1.1

Makes NetworkActivityPlugin always use API from the main thread(thanks, @mgurreta)!

3.1.0

Preliminary support for Swift 3.2 and Swift 4(Xcode 9 beta 6).

3.0.3

Prevent upload requests from being sent using performMultipart method if they are not of .multipartFormData type and vice versa, add specific assertions and error messages.
Added isMultipartRequest property on UploadRequestType.

3.0.2

Improved SPM integration and CI scripts
Added validationClosure properties on APIRequest, DownloadAPIRequest and UploadAPIRequest that allow customizing validation behaviour. Default behaviour, as before, is calling validate() method on Request.

3.0.1

Constructors on APIRequest, UploadAPIRequest, APIStub are made public to allow overriding in subclasses.

3.0.0

Breaking changes

dispatchQueue property was removed from Plugin protocol. All Plugin events are now called synchronously to allow write access to objects, expecially requests. If Plugin requires any specific dispatch queue to run on, it must implement this logic itself.

Bugfixes

APIStub will now print error to console, if it failed to build model from file.
NetworkLoggerPlugin will no longer double escape characters, when printing successful request cURL to console.

2.0.1

Lowers deployment targets to iOS 8 / macOS 10.10

Required dependencies: Alamofire 4.1 and higher.

2.0.0

NetworkLoggerPlugin now has logCancelledRequests property, that allows turning off logging of failing requests, that were explicitly cancelled by developer.
Ensures, that APIStub always calls completion blocks, even if response is not successfully created.

2.0.0-beta.5

APIStub creation is deferred until apiStub property is called.
APIStub model and error properties have been replaced with modelClosure and errorClosure, that are created in APIStub constructor. This is done to allow APIStub to function even if APIRequest has been deallocated.

2.0.0-beta.4

Plugin protocol was rewritten to contain generic methods and more information about what is happening in TRON ecosystem.
ErrorHandlingDataResponseSerializerProtocol and ErrorHandlingDownloadResponseSerializerProtocol now have protocol extensions for default SwiftyJSON error parsing.

2.0.0-beta.3

Parseable protocol was rewritten to directly inherit from Alamofire.DataResponseSerializerProtocol. It allows us to have two generic typealiases - SerializedObject from Alamofire and added to it SerializedError from TRON.
Fixed issue, that could cause completion handlers to be called on background thread.
Use SwiftyJSON instead of forked SwiftyJSON3
parameters property on BaseRequest now contains [String:Any] instead of [String:AnyObject]
processingQueue property on APIRequest was removed.

2.0.0-beta.2

Rewrite Parseable protocol using associatedtype.

2.0.0-beta.1

TRON 2.0 is supported on iOS 9.0, macOS 10.11 and higher due to Alamofire.framework required versions. Read [migration guide](/Docs/2.0 Migration Guide.md) for overview of API changes.

NOTE This release uses forked SwiftyJSON, and SwiftyJSON3 cocoapod, because original repo has not been updated to Swift 3. In future release we hope to use SwiftyJSON cocoapod. Link

API changes

ResponseParseable was rewritten and renamed to Parseable. It now allows creating models without using a constructor. Therefore, it's now possibly to use really any kind of mapper and make factory-like response builders.
Success blocks on APIRequest are now optional and equal to nil by default.
MultipartAPIRequest now becomes a part of larger UploadAPIRequest class.
Introduced new DownloadAPIRequest class, that receives part of APIRequest functionality.

Renamings

Swift 3 API design guidelines have been applied to all API.
perform(completion:) method was renamed to performCollectingTimeline(withCompletion:) to better match method internal behaviour
encoding property on TRON and requests has been renamed to parameterEncoding and now has a different type - Alamofire.ParameterEncoding

Removals

responseBuilder property on APIRequest was removed, as it's no longer used when parsing received response.
JSONDecodable extension on Array is temporarily unavailable due to issues with Swift compiler.
encodingStrategy property on TRON was removed - please use parameterEncoding instead.
TRON.RESTencodingStrategy and TRON.URLEncodingStrategy were removed - please refer to Alamofire 4 migration guide for details.
RequestType enum was replaced by UploadRequestType and DownloadRequestType on DownloadAPIRequest and UploadAPIRequest classes.

1.1.1

Added

Optional progressClosure parameter to rxMultipartUpload method for multipart requests

1.1.0

Added

stubbingShouldBeSuccessful property on TRON, that allows setting up globally, will stubs succeed or not.
encodingStrategy property on TRON instance, that is used to select encoding type based on HTTP Method.
encodingStrategy property on APIRequest, that will be filled with TRON strategy on construction.

By default, for backwards compatibility reasons, we use ParameterEncoding.URL as a default strategy. This will change in next major release of TRON, which will use TRON.RESTEncodingStrategy instead. This encoding strategy uses .JSON encoding for POST, PUT and PATCH requests, and .URL encoding for all other HTTP methods.

Deprecated

encoding property on APIRequest. Please use encodingStrategy property instead.

1.0.0

Changes

None.

If you haven't been following beta releases, please read [1.0.0 Migration Guide](/Docs/1.0 Migration Guide.md) to get an overview of new API additions and phylosophy behind some breaking changes that were made in this release.

1.0.0-beta.3

Breaking changes

ResponseParseable protocol reworked to only include single initializer instead of associated type ModelType. Therefore, all generic methods that previously accepted Model.ModelType type now accept Model type.
Removed performWithSuccess(_:failure:) method, please use perform(success:failure:) method instead.

Added

Ability to create APIRequest with Array generic constraint, for example - APIRequest<[Int],APIError>

Changed

ResponseParseable initWithData: method is now throwable, allowing parsed models to throw during initialization. When initializer throws, APIRequest treats it as a parsing error.

1.0.0-beta.2

Breaking changes

ResponseParseable protocol now accepts NSData instead of AnyObject in its constructor, allowing any kind of parsing, JSON/XML, you-name-it.

1.0.0-beta.1

TRON 1.0 is a major release with a lot of new features and breaking changes. To find out more about philosophy of those and how to adapt to new API's, read [TRON 1.0 Migration Guide](/Docs/1.0 Migration Guide.md)

Breaking changes

RequestToken protocol removed, perform request methods now return Alamofire.Request? to allow customization. When request is stubbed, nil is returned.
tron.multipartRequest(path:) removed, use tron.uploadMultipart(path:formData:) method instead
MultipartAPIRequest performWithSuccess(_:failure:progress:cancellableCallback:) method is replaced by performMultipart(success:failure:encodingMemoryThreshold:encodingCompletion:)
MultipartAPIRequest no longer subclasses APIRequest - they both now subclass BaseRequest.
appendMultipartData(_:name:filename:mimeType:) on MultipartAPIRequest is removed. Please use Alamofire.Manager.MultipartFormData built-in methods to append multipart data
RxSwift extension on MultipartAPIRequest reworked to return single Observable
EventDispatcher class and corresponding TRON.dispatcher, APIRequest.dispatcher property are replaced by TRON and APIRequest properties - processingQueue and resultDeliveryQueue, which are used to determine on which queue should processing be performed and on which queue results should be delivered.
Progress and ProgressClosure typealiases have been removed

Added

upload(path:file:) - upload from file
upload(path:data:) - upload data
upload(path:stream:) - upload from stream
download(path:destination:) - download file to destination
download(path:destination:resumingFromData:) - download file to destination, resuming from data
uploadMultipart(path:formData:) - multipart form data upload
perform(completion:) method, that accepts Alamofire.Response -> Void block.

Deprecations

APIRequest performWithSuccess(_:failure:) method is deprecated, new name - perform(success:failure:)

0.4.3

Fixed

Allow MultipartAPIRequest to use any StringLiteralConvertible value in parameters (for example Int, or Bool e.t.c).

0.4.2

Fixed

Prevent APIRequest from being deallocated if rxResult Observable is passed elsewhere without keeping strong reference to APIRequest itself.

0.4.1

Fixed

Plugins are now correctly notified with "willSendRequest(_:)" method call for multipart requests.

0.4.0

Breaking

Update to Swift 2.2. This release is not backwards compatible with Swift 2.1.
NetworkActivityPlugin now accepts UIApplication in it's initializer to be able to compile in application extensions environments.
NetworkActivityPlugin supports only single instance of TRON. If you have multiple TRONs in your application, consider building another plugin, that uses static variables to track number of requests, similar to old NetworkActivityPlugin from 5639b960e968586d1e24a7adcc6a3420e8648d49.

Added

Added EmptyResponse class that can be used for requests with empty body. For example:

let request : APIRequest<EmptyResponse, MyError> = tron.request("empty/response")

RxSwift extensions for APIRequest and MultipartAPIRequest, usage:

let request : APIRequest<Foo, MyError> = tron.request("foo")
_ = request.rxResult.subscribeNext { result in
    print(result)
}

let multipartRequest = MultipartAPIRequest<Foo,MyError> = tron.multipartRequest("foo")

let (progress, result) = multipartRequest.rxUpload()

_ = progress.subscribeNext { progress in
    print(progress.bytesSent,progress.totalBytesWritten,progress.totalBytesExpectedToWrite)
}

_ = result.subscribeNext { result in
    print("Received result: \(result)")
}

0.3.0

Completion blocks are now handled by new EventDispatcher class, which is responsible for running completion blocks on predefined GCD-queue.

Default behaviour - all parsing is made on QOS_CLASS_USER_INITIATED queue, success and failure blocks are called on main queue.

You can specify processingQueue, successDeliveryQueue and failureDeliveryQueue on dispatcher property of TRON. After request creation you can modify queues using dispatcher property on APIRequest, or even replace EventDispatcher with a custom one.

0.2.1

Added public initializer for NetworkActivityPlugin

0.2.0

Add support for any custom mapper to be used with TRON. Defaulting to SwiftyJSON.

Examples:

Argo, ObjectMapper

Limitations

ResponseParseable and JSONDecodable are now Self-requirement protocols with all their limitations. Apart from that, there are some other limitations as well:

Subclasses

Subclassing ResponseParseable requires explicit typealias in subclassed model:

class Ancestor: JSONDecodable {
    required init(json: JSON) {

    }
}

class Sibling: Ancestor {
    typealias ModelType = Sibling
}

Discussion in mailing Swift mailing lists

Multiple custom mappers

Current architecture does not support having more than one mapper in your project, because Swift is unable to differentiate between two ResponseParseable extensions on different types.

Arrays and CollectionTypes

Currently, there's no way to extend CollectionType or Array with JSONDecodable or ResponseParseable protocol, so creating request with ModelType of array(APIRequest<[Foo],Bar>) is not possible.
