App running on Simulator but "Could not inspect the application package." when trying to run it on my device

You can try to clean the product by pressing Shift+Cmd+K. Also, here you have some more answers that may be useful. Hope that helps!

Hi !

Thank you very much for your answer ! Unfortunatly I tried to clean, etc. I also read the page you mentionned but could not solve my problem with that. I even remade the whole app, code, etc. (very simple) and I get the exact same error.

Thank for your help again.

Below the solution I found.

When I first built the app on my iPhone I had the following error in the debugger :

dyld: Library not loaded: @rpath/libswiftCore.dylib

By looking at some forums, I thought I had to link the UIKit library framework etc. but that was wrong. So I undid that.

The issue comes from the certificates generated automatically by Xcode.

The solution is then :

• Revoke certificates (
• Got to developper.apple.com and follow instructions to generate new certificates
• In Xcode in my project : go to Code Signing Identity and sign both Debug lines with the generated certificate
• Both release lines are set to "iOS Developer"
• Then project > clean
• Build and run on Iphone

and it solves the issue. (The error message "Could not inspect the application package" does not appear anymore and the app runs well).
