Solving the “Could Not Launch Process: Timed Out Waiting for App to Launch” Error

28 February 2025 Stephan Petzl Leave a comment Xcode

Launching an app on a device can sometimes be fraught with unexpected challenges. One common issue faced by developers is the error message: “Could not launch process: timed out waiting for app to launch.” This guide will help you navigate through the possible solutions to resolve this issue effectively.

Understanding the Problem

This error generally occurs when attempting to launch an app on a physical device, despite it working perfectly on the simulator. The root causes can vary, ranging from code signing issues to device settings.

Solutions to Try

1. Verify Code Signing Settings

One of the most common causes is using a Distribution certificate instead of a Developer certificate. Ensure that the code signing settings in Xcode are correctly configured:

  • Navigate to your target in Xcode.
  • Under Build Settings, check the Code signing section.
  • Ensure that a Developer certificate is selected, not a Distribution certificate.

This should be done specifically on the “Target” build settings and not only on the “Project” build settings.

2. Restart Your Device

Sometimes, simply restarting the device you are testing on can resolve the issue. This is a straightforward solution that can often be overlooked.

3. Check Provisioning Profiles

Ensure that your provisioning profiles are up-to-date and correctly configured in Xcode. A missing or expired provisioning profile can cause launch issues.

4. Trust Computer on Device

If prompted, ensure that you have tapped “Trust” on the device when connecting it to your computer. This can prevent the device from blocking the app launch process.

5. Use Debugging Techniques

If the goal is debugging, try attaching the debugger manually:

  • Deploy the app manually on the device.
  • In Xcode, go to Debug > Attach to Process and select your app.

This method allows you to bypass some of the automatic launch processes that might be causing the timeout.
