Definition of 'Protocol' must be imported from module 'ObjectiveC.Protocol' before it is required

[robertoandrade]

I get the following error when compiling a project that has this library as a dependency:

MAObjCRuntime/RTProtocol.m:79:13: Definition of 'Protocol' must be imported from module 'ObjectiveC.Protocol' before it is required

It seems to only happen with XCode 7.3, running 7.2 side by side compiles and runs just fine. Wondering if something changed in 7.3 or the compiler that causes these issues?

Hit this issue when trying to compile after updating XCode. Any known workaround?

I imported objc/Protocol.h at the top of RTProtocol.m and it now compiles.

#import <objc/Protocol.h>
