Code signing issue in Xcode 5

Question

My project has a sub-project. It's not being code-signed:

Even though I disabled code-signing, I still get this error:

Code Sign error: Multiple matching codesigning identities found: Multiple codesigning identities (i.e. certificate and private key pairs) matching “Mac Developer” were found.

When I look in the keychain, there's no duplicate key of "Mac Developer". I didn't have this issue in Xcode 4.x.

How can I fix this?

EDIT

The issue description appears under "LaunchAtLoginHelper", so I'm positive that this project is causing the error.

Answer 1

EDIT

This issue was fixed in Xcode v5.0.1 .
The General tab is now available even in sub-projects.

Apparently you have to open the sub-project separately, because otherwise you will not get the General tab in the projects settings.

Even tough there was no code-signing identity, you need to separately disable code-signing in Xcode 5.

Just choose None , open your main project again and it should compile correctly.
