"Thread1: signal SIGTERM" (in Swift) when changing hardware in iOS simulator

Question

My Swift application is set for certain iOS device, and runs fine in iOS simulator,

However, when changing hardware in iOS simulator, I get this error in Swift

Thread1: signal SIGTERM

I can set Swift for IOS device iPhone 6, IOS simulator runs iPhone 6, but can't change to other hardware (such as iPhone 4S). I can set Swift for IOS device iPhone 4S, and IOS simulator runs fine for iPhone 4S, but get the error when changing hardware (such as iPhone 6 which worked fine before).

Therefore, I am pretty sure the Swift application logic is correct.

How can I solve this?

Answer 1

This is expected behavior. There is nothing to "solve". Your app is correctly being sent SIGTERM because you requested to shutdown the running device and boot a new one (which will terminate all running processes in the existing device).

Answer 2

Use the stop button to close the simulator. The error will be dismissed.
