![]() Now that we have created the two suites we need to add some data to them. override func viewDidLoad() Step 2: Add data to the different suites The first print statement confirms that this works. I am doing everything in the viewDidLoad for this step so that I cannot use these instances of UserDefaults later on. This can be of any UserDefaults valid type, like Integer, String, Bool, 2. We use the Keys enum to set the value of the allowDownloadsOverCellular key to true. Store key-value pairs persistently across launches of your app. I am going to create two suites so that we can see later on how each suite has a different value for the same key. All we have to do is initialize UserDefaults with the suiteName that we want to use. Step 1: Create new suiteĬreating a new suite with UserDefaults is super simple. ![]() I’m using this technique inside Stock Analyzer to populate widgets based on favorite stocks configured in the main application. ![]() Using the global domain is also not allowed as it is not writeable by apps. t('AAPL', 'TSLA', forKey: 'favorite-stocks') Any app or extension configured with the same app group will now be able to read and write the favorite stocks. Your suiteName cannot be the same as your apps bundle identifier. This can allow you to create different UserDefaults for different sections of your app, but it also allows you to share content between multiple apps and extensions that use the same App Group. UserDefaults contains different suites that are identified by their suiteName. Set the value of userAge key to an integer value: defaults. standard Writing data to UserDefaults In order to set the UserDefaults, use one of its set (:forKey:) instance methods. The UserDefaults class doesnt define a convenience method for easily. In order to start using UserDefaults, first, get the standard user defaults object: let defaults UserDefaults.
