Application failed codesign verification. What do I do?

Question

Xcode gives me this warning when I build the app for release.

Application failed codesign verification. The signature was invalid, or it was not signe

Answer 1

My problem was that the Archive scheme did not have Build Configuration of App Store, but of Release. To change this, go to Product -> Edit scheme, select Archive on left side and change Build Configuration to App Store. I am assuming the code signing is configured properly (with distribution certificate).
