SKSpriteNode selector with interval

What's the SpriteKit equivalent of something like this?

[CCNode schedule:@selector(doActivate)
        interval:[[enemyData objectForKey:@"spawnTime"] floatValue]];

Schedulers in Cocos:

[self schedule:@selector(doActivate:)
      interval:[[enemyData objectForKey:@"spawnTime"] floatValue]];

Equivalent in Spritekit using SKAction:

SKAction *wait = [SKAction waitForDuration:[[enemyData objectForKey:@"spawnTime"] floatValue]];
SKAction *performSelector = [SKAction performSelector:@selector(doActivate:) onTarget:self];
SKAction *sequence = [SKAction sequence:@[performSelector, wait]];
SKAction *repeat   = [SKAction repeatActionForever:sequence];
[self runAction:repeat];

You can use SKAction to do this:

+ (SKAction *)performSelector:(SEL)selector onTarget:(id)target or 

+ (SKAction *)runBlock:(dispatch_block_t)block queue:(dispatch_queue_t)queue

combined with:

+ (SKAction *)repeatActionForever:(SKAction *)action

and

+ (SKAction *)waitForDuration:(NSTimeInterval)sec

for a delay between each call
