Hello, I'll post the error log below. Newly created projects will build, but once they're modified the build fails. I don't have any warnings, or errors in the Signing & Capabilities window. The Team and Bundle Identifier are satisfied. Everything seems to checkout in the Provisioning Profile. Signing Cerfificate points at my email address.

I've tried to follow some suggestions from searching google, but that's not getting me anywhere.

Any suggestions are appreciated,

Progress Report

CodeSign becomes problematic after adding the Content folder with Copy and Groups. To worm around the issue, without knowing what's actually happening, create the bundle, build, add Content, and then Product / Clean Build Folder. Additionally, Erase all Content and Settings in the Simulator. I doubt that affects the CodeSign, but it keeps the simulator free of the many failed Projects. I guess cleaning the build folder after modifying the bundle seems like the key.

Interestingly enough the error provides a hint "resource fork, Finder information, or similar detritus not allowed Command CodeSign failed with a nonzero exit code." Maybe we're cleaning out conflicting detritus something or others. :)
