Override application delegate on iOS with SDL2

main.mm

// You can use this in your main.mm

#import "../SDL/include/SDL_uikitappdelegate.h"

@interface MyDelegate : SDLUIKitDelegate
@end

@implementation MyDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    BOOL ret = [super application:application didFinishLaunchingWithOptions:launchOptions];
    NSLog(@"Owning the place!");
    
    return ret;
}
@end

// Add a 'category' to the SDL app delegate class
@interface SDLUIKitDelegate (extra)
{
}
@end

@implementation SDLUIKitDelegate (extra)
+ (NSString *)getAppDelegateClassName {
    return @"MyDelegate";
}
@end

I wonder how to avoid XCode complaining on line 25, but otherwise this is very useful, thanks a lot!
