You have an outlet that doesn't exists anymore. Check the connections inspector for lost connections.

Your error is Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key docPassword.

Usually this means that the .xib file (or storyboard) for your viewController contains an outlet (docPassword in your case) that isn't in your code. You should either add the property in your code or remove the outlet entirely in interface builder.

do you mean redo back the outlets? – Bedd Jun 03 '15 at 09:37
Either reconnect/recreate the outlets or remove them, yes. – donnywals Jun 03 '15 at 09:55
