I have an app in SwiftUI. When i enter the app i create a simple live activity. Everything works as expected. When I close the app the live activity still works and that's the intended behaviour but when I reopen the app another live activity is created.
How can I get a reference to the first live activity that i created so I would not have two?
You can access the currently running live activities on app start with
Activity<ContentAttributes>.activities (optionally filter them or use the first one if you only have one). Only if there is no activity running you should start a new one.
See Apple's documentation for more info.
