Warnings: unarchiveObject(with data: Data) deprecated since iOS 12.0

[ragu-pdx]

Getting warnings pointing to this deprecation:

@available(iOS, introduced: 2.0, deprecated: 12.0, message: "Use +unarchivedObjectOfClass:fromData:error: instead")
open class func unarchiveObject(withFile path: String) -> Any?

being called from:

public struct DefaultsUrlBridge: DefaultsBridge {

    public func deserialize(_ object: Any) -> URL? {
        if let object = object as? URL {
            return object
        }

        if let object = object as? Data {
            return NSKeyedUnarchiver.unarchiveObject(with: object) as? URL
        }

        if let object = object as? NSString {
            let path = object.expandingTildeInPath
            return URL(fileURLWithPath: path)
        }

        return nil
    }
}

and twice in this struct:

public struct DefaultsKeyedArchiverBridge<T>: DefaultsBridge {

    public init() {}

    public func save(key: String, value: T?, userDefaults: UserDefaults) {
        guard let value = value else {
            userDefaults.removeObject(forKey: key)
            return
        }
        // Needed because Quick/Nimble have min target 10.10...
        if #available(OSX 10.11, *) {
            userDefaults.set(NSKeyedArchiver.archivedData(withRootObject: value), forKey: key)
        } else {
            fatalError("Shouldn't really happen. We do not support macOS 10.10, if it happened to you please report your use-case on GitHub issues.")
        }
    }

    public func get(key: String, userDefaults: UserDefaults) -> T? {
        guard let data = userDefaults.data(forKey: key) else {
            return nil
        }
        return deserialize(data)
    }

    public func deserialize(_ object: Any) -> T? {
        guard let data = object as? Data else { return nil }
        return NSKeyedUnarchiver.unarchiveObject(with: data) as? T
    }
}

This is also creating a problem in a project I just started.
All of a sudden my project would just freeze the build for no reason or breakpoint.
I swapped all the defaults out with https://github.com/sindresorhus/Defaults project as it is a similar way the default Keys are created.
This worked though if you've got a big project it would be a pain. There is something in Swifty that is causing a hang when building.
Something to do with maybe the syntax when using the keys. -> "."
