How can I access a user-defined Xcode build setting?

Question

If I added a user-defined setting in my build configuration, how can I read that setting in my Objective-C code?

I have two files in my project, debug.plist

Answer 1

You can access your user-defined build setting at run-time (as suggested in a comment by @JWWalker)

1. Add an entry to your Info.plist file, and set it to your User-defined Build Setting

   MySetting -> ${MYSETTING}
   

2. Read its value from code

   Objective-C

   [[NSBundle mainBundle] objectForInfoDictionaryKey:@"MySetting"];
   

   [Edit] Swift

   guard let mySetting = 
     Bundle.main.object(forInfoDictionaryKey: "MySetting") as? String 
       else { print("MySetting not found") }
