NSArray can't shuffle

I am trying to use the new shuffle method to shuffle my array: https://developer.apple.com/documentation/foundation/nsarray/1640855-shuffledarray?language=objc. But I just get an error saying: No visible @interface for 'NSArray' declares the selector 'shuffledArray' .

This is my code:

NSArray *shuffledArray = [array shuffledArray];

And my project is iOS 10.0+

As you can see on the right column of the documentation, although this is a method on NSArray , it's located in the GameplayKit framework.

You need to import the framework :

#import <GameplayKit/GameplayKit.h>

---

You should always use @import for this, as it offers some advantages over #import of frameworks. So on this case it would be: @import GameplayKit;
