Expense Tracker in SwiftUI

An app to manage your expenses which you will waste (just like me), used MVVM architecture.

Persistence of Transactions

I have built a cache manager to store all the user transactions data in the memory as a cache. If you want to implement your custom class to manage them, you can do the following:

1. Create a class which conforms to the protocol UserTransaction.
2. Implement the functions defined inside the protocol.

protocol UserTransaction {
    func isUserAlreadyExist(userName: String) -> Bool
    func removeUser(userName: String)
    func saveTransaction(userName: String, transactions: [Transaction])
    func getTransactions(userName: String) -> [Transaction]
    func removeTransaction(userName: String, transactions: [Transaction])
    func getUserExpenseModel(userName: String) -> UserExpenseModel?
}

class YourCustomClass: UserTransaction {
    // UserTransaction Implementation
}

3. Pass the same class as a parameter(dependency injection) where TransactionListViewModel is initialized, inside the Expense_TrackerApp.swift.

 @StateObject var transactionViewModel = TransactionListViewModel(userAPIDelegate: YourCustomClass())
