Strange errors at runtime - tutorial iOS 3a

physiowear

I've completed the tutorial for iOS 3a from the "Getting Started Guide". I'm sure I've installed CocoaPods correctly but when I run it I am getting several unusual errors from some of the code in the library files, including:

Any ideas what could cause this? Thanks in advance.

Hi Physiowear,

This type of error is usually caused by some kind of typo in one or more of the source files. Can you make a completely clean copy of the sample project and try again?

Thanks,

Also, please make sure that your Xcode is updated to the latest version.
