Issue #502 Mutation is used to mutate state synchronously. Action is like intent, either from app or from user action. Action maps to Mutation in form of Publisher to work with async action, similar to redux-observable AnyReducer is a type erasure that takes the reduce function import Combine import Foundation public protocol Reducer { associatedtype State associatedtype Mutation func reduce(state: State, mutation: Mutation) -> State } public struct AnyReducer<State, Mutation> { public let reduce: (State, Mutation) -> State public init<R: Reducer>(reducer: R) where R....

Issue #499 Build setting Build Library For Distribution Binary Frameworks in Swift It turns on all the features that are necessary to build your library in such a way that it can be distributed What does this error actually mean? Well, when the Swift compiler goes to import a module, it looks for a file called the Compiled Module for that library. If it finds one of these files, it reads off the manifest of public APIs that you can call into, and lets you use them....

Issue #497 Synthetic properties generated by Kotlin Android Extensions plugin needs a view for Fragment/Activity to be set before hand. In your case, for Fragment, you need to use view.btn_K in onViewCreated override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { super.onCreateView(inflater, container, savedInstanceState) val view = inflater.inflate(R.layout.fragment_card_selector, container, false) view.btn_K.setOnClickListener{} // access with `view` return view } Or better, you should only access synthetic properties in onViewCreated override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?...

Issue #496 Read this Restoring Purchased Products to understand the purposes between the 2. From iOS 7, every app downloaded from the store has a receipt (for downloading/buying the app) at appStoreReceiptURL. When users purchases something via In App Purchase, the content at appStoreReceiptURL is updated with purchases information.

Issue #493 Declare in Podfile pod 'Firebase/Core' pod 'Firebase/RemoteConfig' Use RemoteConfigHandler to encapsulate logic.

Issue #492 Suppose we have a base Localizable.strings "open" = "Open"; "closed" = "Closed"; After sending that file for translations, we get translated versions. "open" = "Åpen"; "closed" = "Stengt"; Searching and copy pasting these to our Localizable.strings is tedious and time consuming. We can write a script to apply that. Remember that we need to be aware of smart and dump quotes .replace(/\"/g, '') .replace(/\"/g, '') const fs = require('fs') const originalFile = 'MyApp/Resources/nb....

Issue #488 The dollar is not a prefix, it seems to be a generated code for property wrapper, and each kind of property wrapper can determine which value it return via this dollar sign State and ObservedObject are popular property wrappers in SwiftUI State Read State A persistent value of a given type, through which a view reads and monitors the value. If we have a simple State, we can access its 3 forms...

Issue #487 In case we have to modify state when another state is known, we can encapsulate all those states in ObservableObject and use onReceive to check the state we want to act on. See code Avengers If we were to modify state from within body function call, we will get warnings Modifying state during view update, this will cause undefined behavior. This is similar to the warning when we change state inside render in React...

Issue #485 The easiest way to show image picker in iOS is to use UIImagePickerController, and we can bridge that to SwiftUI via UIViewControllerRepresentable First attempt, use Environment We conform to UIViewControllerRepresentable and make a Coordinator, which is the recommended way to manage the bridging with UIViewController. There’s some built in environment property we can use, one of those is presentationMode where we can call dismiss to dismiss the modal....
