Build error importing TrustKit.h into .mm file

[cohenadair]

Importing TrustKit into an Objective-C++ (.mm) file via #import <TrustKit/TrustKit.h> results in the following build error:

Use of '@import' when C++ modules are disabled, consider using fmodules and fcxx-modules

From what I've read, C++ modules are disabled for Objective-C++ files, and the @import directive isn't allowed.

This seems to be a common problem in Pod libraries, other's have fixed it by doing something like:

#if __has_feature(modules)
    @import Foundation;
#else
    #import <Foundation/Foundation.h>
#endif

For others having this issue

A workaround is to create a TrustKitWrapper.h/m class and create wrapper methods for TrustKit APIs you need, then import TrustKitWrapper.h into your .mm files. Something like:

@interface TrustKitWrapper : NSObject

+ (void)setupTrustKitInstance;
+ (bool)handleChallenge:(NSURLAuthenticationChallenge *)challenge;

@end

Thanks @cohenadair , I do have the same issue here tryin to import TrustKit in Cedar BDD Testing. How about making a PR?

@boehlefeld I'm not likely to have the time anytime soon, but I'll add it to my list of things to do.
