Changing the way we import specs on iOS

[atlj]

We are using header files on iOS to specify module interfaces. For the new architecture, we are getting the interface from the codegen-generated specs. An example header file would be:

#ifdef RCT_NEW_ARCH_ENABLED
#import "RNAwesomeLibrarySpec.h"
#import <React/RCTEventEmitter.h>

@interface AwesomeLibrary : NSObject <NativeAwesomeLibrarySpec>
#else

#import <React/RCTBridgeModule.h>

@interface CoreNative : NSObject <RCTBridgeModule>
#endif

@end

However, there is a simple problem with this approach. If you try to import this header file from the app delegate, it breaks the builds as it cannot find the spec file. An easy solution to this problem that I came across is from react-native-bootsplash.

If we update the import like this, the problem would be solved and the functionality is the same:

#ifdef RCT_NEW_ARCH_ENABLED
#import <RNAwesomeLibrarySpec/RNAwesomeLibrarySpec.h> // This is changed
#import <React/RCTEventEmitter.h>

@interface AwesomeLibrary : NSObject <NativeAwesomeLibrarySpec>
#else

#import <React/RCTBridgeModule.h>

@interface CoreNative : NSObject <RCTBridgeModule>
#endif

@end
