Conditional compiling in Swift

I want to use flags to control the compiler in Swift. Like we use #ifdef, #ifndef, #else, #endif in C (and C++, Objective C, ....)

I found the way to do it on the net, but I hit a problem in the following case. Anyone reading will understand what I want. Nevertheless the compiler complains. What is the way to go around? Of course without having to copy two times the same ten or more lines.

#if UseAds
class ViewController: UIViewController,XYZBannerDelegateProtocol {
#else
class ViewController: UIViewController {
#endif

Note that I got the information I am using here: http://en.swifter.tips/condition-compile/ which is similar to what can be found here.

But none of these solves my problem. They only tell me the basic way to do it.

You can use like this :

class ViewController: UIViewController {
    // Your common functions
}
#if UseAds
    extension ViewController: XYZBannerDelegateProtocol {
        // Your delegate methods    
    }
#endif
