Why cant i use CAKeyFrameAnimation with SpriteKit ?

I cannot add the animation to the node because it should be [node addAnimation:animation forKey:nil]; instead but there is an error that says "NO visible @interface for 'SKSpriteNode' declares the selector 'addAnimation:forkey'". ?

SKSpriteNode *node = [SKSpriteNode spriteNodeWithColor:[SKColor redColor] size:CGSizeMake(40, 40)];
    node.name = @"node";
    node.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));
    [self addChild:node];

    CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"position.x"];
    animation.values = @[@0, @20, @-20, @0];
    animation.keyTimes = @[@0, @0.25, @0.50, @0.75, @1.0];
    animation.duration = 2.0;
    animation.repeatCount = 1.0;
    [node animationDidStart:animation];
