Hi 
Problem at run application in xcode 11
Search in google but don’t I have not found the solution
Command codesing failed with nonzero exit code
Please
Is this your first time running the application? What were you doing before this error happened?
I didn’t do anything, I just applied the card app
The problem appeared with me a while ago … When it appears, delete the application and then create it again, but this is difficult … Is there no solution🥺
Hi,
Couple possibilities.
-
Did you add a folder as a reference rather than a group? If the former, take the files out of that folder and delete it and create a group of those files.
-
You might also want to try the following and see if it clears:
- Open keychain access.
- Lock the ‘login’ keychain. (right clicking on “login” in the upper left panel)
- Unlock it, enter your Mac account password.
- Clean Project in the product menu.
- Build it Again.
Let us know and we can try again.
Blessings,

I did not add any folder
But The second way
Please can you explain it to me in pictures
Ok try this.
In a Finder window, type Keychain Access
The Keychain panel will open when you type a return. On the left, Right Click the Login and elect Lock. Then Right click and unlock it. A standard unlock window will pop up and you type in your Mac’s password.
Finally, open your project again and choose Clean from the Product menu, and after it cleans build the project again.
See if that clears your error.
