28 February 2025 Stephan Petzl Leave a comment Xcode

Encountering the “iPhone has denied the launch request” error while using Xcode 9 can be a perplexing experience, particularly when your app appears to build successfully but fails to launch. This article provides a structured approach to resolving this issue by leveraging insights from various solutions.

Understanding the Issue

This error typically arises when attempting to run an app on a physical iOS device rather than a simulator. It often results from discrepancies in code signing or configuration settings within Xcode.

Step-by-Step Solutions

1. Check Code Signing

Ensure that your app is signed with a developer profile rather than a distribution profile. This is a common oversight that can prevent the app from launching correctly on a device.

2. Adjust Debug Executable Settings

Another potential solution involves the “debug executable” option within Xcode:

  • Navigate to Product > Scheme > Edit Scheme.
  • Select the Info tab.
  • Uncheck the Debug Executable checkbox.

This adjustment has been known to resolve not only the launch request denial but also other related issues, such as missing console output.

3. Use the “Ask on Launch” Option

If the above solutions do not work, consider setting your scheme to “Ask on Launch”:

  • Go to Product > Scheme > Edit Scheme.
  • Under the Info tab, set Executable to Ask on Launch.

While this method is slightly inconvenient, it has proven effective for some users.

Additional Considerations

In some cases, the problem may be linked to a free developer account or other account settings. Ensure that your account and device are properly configured and trusted.
