Need some help with SpriteKit please

Currently in the process of making a sprite kit game and I am getting a yellow flag. The game works but I don't think this is good for submission. So here it is:


@protocol SceneDelegate <NSObject>
- (void) eventStart;
- (void) eventPlay;
- (void) eventWasted;

@interface Scene : SKScene<SKPhysicsContactDelegate>

**@property (unsafe_unretained,nonatomic) id<SceneDelegate> delegate;** 

 ^^Property type 'id<SceneDelegate>' is incompatible with type 'id<SKSceneDelegate>' inherited from 'SKScene'^^

@property (nonatomic) NSInteger score;

- (void) startGame;


Anyone know what the fix for this would be? Please and thank you in advance.
