The app name must be unique, but the display name (the text under the icon) has no such constraint. We can both make apps for keeping track of twinkies, which we would have to uniquely name in the app store (Twinkie Tracker 1000 and Twinkie Tracker Pro), but we could both use Twinkie Tracker as the display name of our respective apps.

I have no idea why the word was filtered out. In short, app names must be unique, but display names do not need to be unique.

For reference, the onRecieve modifier is executing every 3 seconds when the timer publishing interval is set to 3 seconds: .onReceive(timer) { _ in print("got here: \(Date())") withAnimation(nucleusAnimation) { print("animation got here: \(Date())") nucleusRadius = Double.random(in: minSize...maxSize) } } got here: 2024-10-27 14:05:58 +0000 animation got here: 2024-10-27 14:05:58 +0000 got here: 2024-10-27 14:06:01 +0000 animation got here: 2024-10-27 14:06:01 +0000 got here: 2024-10-27 14:06:04 +0000 animation got here: 2024-10-27 14:06:04 +0000 got here: 2024-10-27 14:06:07 +0000 animation got here: 2024-10-27 14:06:07 +0000 got here: 2024-10-27 14:06:10 +0000 animation got here: 2024-10-27 14:06:10 +0000 In addition, changing the timer instantiaton as follows, which appears to be more correct, did not change the CPU use: .onReceive(Timer.publish(every: 1, on: .main, in: .common).autoconnect()) { output in withAnimation(nucleusAnimation) { nucleusRadius = Double.random(in: minSize...maxSize) } }

The problem is repeatForever. Please see my post and answer on Stack Overflow for more information.
