It's definitely an Apple code signing issue. I connected my phone to my mac with a cable and created a brand new test project. I ran it on the simulator and it ran and showed hello world. When tried to run it on my phone, it errored (Command CodeSign failed with a nonzero exit code). If you would please help me debug code signing, I would really appreciate it. Thanks!

And my test project was as you said, created from the ios App template. There was no 3rd party code.

I see the whole error now, thanks to your instructions, but i still don't understand it/know how to fix it: CodeSign /Users/mjw/Library/Developer/Xcode/DerivedData/test3-fplwbgvlqthlalgvxynxjlnmsemc/Build/Products/Debug-iphoneos/test3.app/test3.debug.dylib (in target 'test3' from project 'test3') cd /Users/mjw/Documents/Projects/Current/test2/test3 Signing Identity: "Apple Development: Full Name (V6775UBEAS)" Provisioning Profile: "iOS Team Provisioning Profile: *" (982489b4-4832-4f77-8246-e8b1ea49eff1) /usr/bin/codesign --force --sign 6411F4C28E0E1A991FBFE8E1F1A89B77B589EC21 --timestamp\=none --generate-entitlement-der /Users/mjw/Library/Developer/Xcode/DerivedData/test3-fplwbgvlqthlalgvxynxjlnmsemc/Build/Products/Debug-iphoneos/test3.app/test3.debug.dylib Warning: unable to build chain to self-signed root for signer "Apple Development: Full Name (V6775UBEAS)" /Users/mjw/Library/Developer/Xcode/DerivedData/test3-fplwbgvlqthlalgvxynxjlnmsemc/Build/Products/Debug-iphoneos/test3.app/test3.debug.dylib: errSecInternalComponent
