Issue #529 indexPath https://developer.apple.com/documentation/uikit/uicollectionviewlayoutattributes/1617786-layoutattributesfordecorationvie It is up to you to decide how to use the indexPath parameter to identify a given decoration view. Typically, you use the decorationViewKind parameter to identify the type of the decoration view and the indexPath information to distinguish between different instances of that view.

Issue #518 let userDefaults = UserDefaults(suiteName: suiteName) userDefaults.removePersistentDomain(forName: suiteName) https://developer.apple.com/documentation/foundation/userdefaults/1417339-removepersistentdomain Calling this method is equivalent to initializing a user defaults object with init(suiteName:) passing domainName, and calling the removeObject(forKey:) method on each of its keys.

Issue #504 https://twitter.com/NeoNacho/status/1181245484867801088?s=20 There’s no way to have platform specific sources or targets today, so you’ll have to take a different approach. I would recommend wrapping all OS specific files in #if os and just having one target. For tests, you could do something similar, one test target, but conditional tests Every files are in Sources folder, so we can use platform and version checks. For example Omnia is a Swift Package Manager that supports iOS, tvOS, watchOS, macOS and Catalyst....

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. Most of the cases, you just need to refresh the receipt (at appStoreReceiptURL) so that you know which transactions users have made....

Issue #469 If there are lots of logics and states inside a screen, it is best to introduce parent and child container, and switch child depends on state. Each child acts as a State handler. In less logic case, we can introduce a Scenario class that holds the state. So the ViewController can be very slim. The thing with State is that all possible scenarios are clear and required to be handled...

Issue #461 With UIAlertController we can add buttons and textfields, and just that func addAction(UIAlertAction) func addTextField(configurationHandler: ((UITextField) -> Void)?) To add custom content to UIAlertController, there are some workarounds Add content onto UITextField Restyle UITextField and add custom content Subclass UIAlertController and handle UI in viewWillAppear By subclassing we can tweak the whole view hierarchy and listen to events like layout subviews, but this can be very fragile. Make custom UIViewController that looks like UIAlertController This is the correct way but takes too much time to imitate UIAlertController, and have to deal with UIVisualEffectView, resize view for different screen sizes and dark mode...
