Xcode 8 (OS X Sierra) and the keychain

[MichaelDavis3]

Fun fact:  Xcode 8 seems to have a new feature/bug... turns out you can't access the keychain AT ALL unless you turn on Keychain Sharing in the Capabilities section of the app target.

So if you are like me and you use the keychain to store runtime codes, user credentials, etc... go ahead and save yourself a couple of hours of tearing your hair out 🙂
