What did you do?

mobile go version is the latest

For iOS

Following this instruction

• executed command

gomobile build -target=ios -bundleid=org.golang.gomobiletest \
-o=basic.app golang.org/x/mobile/example/basic

• drag&drop to the iOS simulator

iOS simulator version
- iPhone 13(iOS 17.5)
- iPhone 15(iOS 17.5)

• open the app then it closes without any log

I also tried with -iosversion=15 but it also didn't work.

For macOS

• env

macOS: Sonoma 14.3.1

• executed command

gomobile build -target=macos -bundleid=org.golang.gomobiletest \
-o=basic.app golang.org/x/mobile/example/basic

• open the app
• this error is shown

What did you see happen?

As the described above,

• For the iOS app, the app closes without any error.
• For the macOS app, the app shows the error that it cannot be opened.

What did you expect to see?

The app is opening without any issue.
