What does it mean when codesigning exits with code 3 but only on the emulator?

edit

Exit code 3 typically indicates that there was an error during the code signing process. However, since the error occurs only on the emulator, it could be due to a variety of reasons such as:

1. The security settings on the emulator are preventing the code signing process from completing successfully.

2. The emulator may not have the required certificates or provisioning profiles installed.

3. The project settings, such as the bundle ID, may not be configured correctly for the emulator, causing code signing to fail.

To troubleshoot this issue, you can try the following steps:

1. Make sure that the emulator is configured correctly with the required certificates and provisioning profiles.

2. Check the bundle ID and other project settings to ensure that they are configured correctly for the emulator.

3. Verify that the security settings on the emulator are not blocking the code signing process.

4. Check the console or log files for error messages that may provide more information about the error.
