Awesome! You made my day! Thanks!

Okay, I found a way to use debug print in a Live Activity. You can need the Console.app on Mac OS and use the Logger struct in the os framework. import os let logger = Logger(OSLog(subsystem: "com.yourapp.identifier", category: "General")) logger.info("Your message to print in Console.app"

I am answering my own comment above, but since Live Activity is its own contained process, there is no way to attach the XCode debugger to it. Nonetheless you can observe the logs from liveactivitiesd in the Console app on Mac, but that's not very useful.

Well, I guess, now that I understand better how the Live Activity works, there is no way to attach the debugger. Live Activity is a very basic component that requires minimal computing.

But are you able to attach the debugger to your Live Activity Scheme? Can you set breakpoints and enable the debug console?

Yeah, that does the trick! Now I need to figure out how to change it on XCode Cloud.

Yeah, that's what did the trick for me!

Wrapping tabBarController.selectedIndex = selectedIndex into UIView.performWithoutAnimation did the trick for me. UIView.performWithoutAnimation { tabBarController.selectedIndex = selectedSegmentIndex }

Awesome! That was it! Thank you for your comment @zulfishah! Very helpful!
