Codesign error: Provisioning profile cannot be found after deleting expired profile

Sometimes your Xcode project file gets messed up, especially if you have an old project and first created it with an older version of Xcode/iPhone SDK.

What you need to do is open up the project file in a text editor, search for the 'long string' from your error and manually erase that line.

In fact, you should just go ahead and erase any line that points to any provisioning profiles. Then reopen the project in Xcode, go to the settings and reselect your new profile. This clears up issues like that most of the time.

The lines that point to the provisioning profiles will look like this:

PROVISIONING_PROFILE = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";
"PROVISIONING_PROFILE[sdk=iphoneos*]" = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";

Here's a simpler solution that worked for me and which doesn't require the manual editing of the project file:

In Xcode, in the "Groups & Files" pane, expand "Targets" and double-click on your app's target. This brings up the Info pane for the target. In the "Build" section, check the "code signing" section for any old profiles and replace with the correct one.

Note that this is different from double-clicking on your project icon and changing the profile from there. Quite amazing :)

1. Project&Targets Properties -> "Don't Code Sign" -> OK -> cmd+S(or cmd+B);

2. Project&Targets Properties -> "Your Provision Profile"-> OK

3. Everything works again!

I agree with Brad's answer, that you can fix this problem by editing your target/project by hand, deleting any lines like this:

PROVISIONING_PROFILE = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";
"PROVISIONING_PROFILE[sdk=iphoneos*]" = "487F3EAC-05FB-4A2A-9EA0-31F1F35760EB";

However, in Xcode 4.2 and later, there is a much easier way to access this text and select and delete it. In the Project Navigator on the left, select your project (the topmost line of the Project Navigator). Now simply choose View > Version Editor > Show Version Editor. This displays your project as text, and you can search for PROVISIONING and delete the troublesome line, right there in the editor pane of Xcode.
