Swift share nsuserdefaults in multiple views

How can I get this selected background color to load in my other view controllers? I don't seem to get it running by implementing it into the ViewDidLoad of my other views, as I've done in the options view (see below). This works perfectly and the next time the app opens, the right color is still selected. While developing extensions in iOS, you may find a need. Once clicked, users click on a button to save their preference color to NSUserDefaults. With the NSUserDefaults class, you can save settings and properties related to application or user data. The idea to store the data in NSUserDefault is good, But to store more value in NSUserDefault take too much time to load the apps, so make slow of Apps. I have multiple view controllers in my app, one of which is an 'options' view in which users can change certain settings like the background color through a segmented control. Here, setting the view constraints is easier. Share and Enjoy Quinn The Eskimo Apple Developer Relations, Developer Technical Support, Core OS. Answer (1 of 2): One simple way would be to add UIViews to your view controller in the storyboard and creating outlets to the view controller class. The only way that two apps can share an app group is if they are published by the same team. Note that the gating factor here is the Team ID.

I did a thorough research, but didn't seem to find the answer i'm looking for. If Apps are part of the same app group, they can share data through that app group.
