Cannot run the project on an iPhone

Hi everyone,

Has anyone experienced something similar when running a project on a real iPhone?

I’m trying to run my project on my iPhone using Xcode, but I’m getting a “signal 9” error in the debugger. When I hit the Run button, the iPhone screen stays black with a small loading icon in the middle for a while, and then the device just returns to the lock screen.

I’ve run another project and it’s working perfectly.
The issue is only with my current project.

Any ideas what might be causing this?

Thanks in advance!

Do you have a paid developer account?
If you don’t you will find that you are limited in the number of projects you can run on your real device in a given period of days and they only remain active for a short period of time.

If you do have an active paid developer account then try creating a fresh simple project and see if that runs on the real device. If that is successful then you need to look closely at your project that is not working.

Thank you for your reply.

Other projects run on my real device and they work correctly. Only this project is not running.
I think I might need to change something on my project.
