SpriteKit : Easy question but how do I spawn different nodes at different times?

I used the SpaceCat update method as a foundation. Basically right now the Space dogs and the coins are being randomly added to the scene every 1.5 sec.

Is there a way to delay the time the coins are added?

how can i implement something similar to a SKAction waitForDuration: .5] completion:^{ so that the coins will spawn at a delayed time after the space dogs. I don't want them appearing at the same time .....

-(void) update:(NSTimeInterval)currentTime {

if (self.lastUpdateTimeInterval) {
    self.timeSinceSpaceDogAdded += currentTime -self.lastUpdateTimeInterval;
    self.totalGameTime += currentTime - self.lastUpdateTimeInterval;
}

if (self.timeSinceSpaceDogAdded > self.addSpaceDogTimeInterval && !self.gameOver) {

    [self addSpaceDog];
    [self addCoins];



    self.timeSinceSpaceDogAdded = 0;

}
self.lastUpdateTimeInterval = currentTime;

if (self.totalGameTime > 60) {
    self.addSpaceDogTimeInterval= 1.5;


}else if (self.totalGameTime >45 ) {
    self.addSpaceDogTimeInterval= 1.5;
}else if (self.totalGameTime >30 ) {
    self.addSpaceDogTimeInterval= 1,5;
}else if (self.totalGameTime >2) {
    self.addSpaceDogTimeInterval= 1.5;

}

Just as you have self.timeSinceSpaceDogAdded > self.addSpaceDogTimeInterval you can create one for the coins: self.timeSinceCoinsAdded > self.addCoinsTimeInterval
