Parse Starter Project LogIn and Register View Controllers Errors
I had this same issue. The login related classes for parse require you to add two additional frameworks beyond what is listed in their quick start documentation:
Social.frameworkAccounts.frameworkThese frameworks are part of iOS. Simply go to the projects Build Phases->Link Binary with Libraries and add them. I hope you find this helpful.
They didn't mention in the Quick start this two.
Social.frameworkAccounts.frameworkThis library has been included in the parse.zip, with Bolts we clean the last 4 errors.
Bolts.framework
I was receiving the exact same error while attempting to complile the Parse Starter project. So I followed the advice in this post: https://stackoverflow.com/a/7847881/3960969, and everything seemed to work.
Basically, all I had to do was remove the reference to and re-install these frameworks:
Social.frameworkAccounts.frameworkAfter that, the project compiled without any errors or warnings.
