1) Xcode compilator revolution:

• Xcode 4: LLVM-GCC for default, but GCC still available.
• Xcode 4.2: LLVM 3.0 for default, GCC expropriated.
• Xcode 4.6: update to LLVM 4.2. 
• Xcode 5: update to LLVM 5.0, LLVM-GCC expropriated. GCC to LLVM transition completed.

2) How to integrate Unity into iOS app.

3) How send data between Unity and iOS app.

Integration of Unity:

1) Скопировать папки Classes и Libraries (Create groups). Добавить Data (Create folder references);

2) Удалить ссылки на все .h в папке Classes/Native и удалить папку Libraries/libil2cpp (Remove references);

3) Изменить код в UnityAppController.h;

inline UnityAppController* GetAppController()

{

return (UnityAppController*)[UIApplication sharedApplication].delegate;

}

на

NS_INLINE UnityAppController* GetAppController()

{

NSObject<UIApplicationDelegate>* delegate = [UIApplication sharedApplication].delegate;

UnityAppController* unityController = (UnityAppController *)[delegate valueForKey:@"unityController"];

return unityController;

}

4) Удалить из Compile sources дубликат main.mm из папки Classes;

5) Закомментить IMPL_APP_CONTROLLER_SUBCLASS(VuforiaNativeRendererController), если есть Vuforia.
