How To Test if Running on iOS, watchOS or tvOS

[kjmcneish]

You can use the following conditional compilation statements along with the os() function to determine if your app is running on iOS, watchOS, or tvOS.

In Swift:

Code: [Select]

#if os(iOS)
           
#elseif os(watchOS)
           
#elseif os(tvOS)
           
#endif
In Objective-C:

Code: [Select]

#ifdef TARGET_OS_IOS
   
#elif TARGET_OS_WATCHOS
   
#elif TARGET_OS_TV
   
#endif
All the best!
