-[NSObject conformsToProtocol:] does not work.

[rupertdaniel]

Using the latest pre-release 0.2.180221-dev-20180516000001 -[NSObject conformsToProtocol:] does not work.

To reproduce the issue the Protocol, the object that implements the Protocol, and the code that calls -[NSObject conformsToProtocol:] need to be in separate source files.

If all 3 are defined in the same source file then it works as expected.

For example:

TestProtocol.h

#import <Foundation/Foundation.h>
@protocol TestProtocol <NSObject>
@end

TestObject.h

#import <Foundation/Foundation.h>
#import  "TestProtocol.h"

@interface TestObject : NSObject <TestProtocol>

@end

TestObject.m

#import "TestObject.h"
@implementation TestObject

@end

In some other source file...

TestObject *to = [[TestObject alloc] init];
if ([to conformsToProtocol:@protocol(TestProtocol)]) {
	NSLog(@"YES");
} else {
	NSLog(@"NO");
}

This will result in conformsToProtocol: to return FALSE and printing NO.
