Spawning sprites not working - ios

Question

Ok I'm fairly new to coding with sprite kit so I don't know too much. I'm trying to make 5 bricks spawn above the scene and then slide down into the scene every 5 seconds. I thought this code would work but it does absolutely nothing to my scene.
I have another method that has bricks already loaded into the scene and that works so I don't think that would affect this much but not really sure.
-(void) spawnMoreBricks:(CGSize)size {
for (int i = 0; i < 5; i++) {
SKSpriteNode *brick = [SKSpriteNode spriteNodeWithImageNamed:#"brick"];
//resize bricks
brick.size = CGSizeMake(60, 30);
//position it
brick.position = CGPointMake(self.size.width/2, self.size.height);
SKAction *wait = [SKAction waitForDuration:5];
SKAction *spawn = [SKAction scaleTo:1 duration:0];
SKAction *move = [SKAction moveByX:0 y:-80 duration:3];
SKAction *spawnSequence = [SKAction sequence:#[wait, spawn, move]];
[self runAction:spawnSequence];
}
}

Answer 1

SKAction *wait = [SKAction waitForDuration:5];
SKAction *spawn = [SKAction runBlock:^{[self addChild: brick];
SKAction *move = [SKAction moveByX:0 y:-80 duration:3];
[brick runAction: move];
}];
SKAction *spawnSequence = [SKAction sequence:#[wait, spawn]];
[self runAction:spawnSequence];
Here is a modified set of actions to use. The problem was that you were running all the actions on the scene itself. The code provided runs a sequence on the scene that waits 5 seconds (acting as the delay), and then runs a spawn action. runBlock allows us to add the brick to the scene, create the move action, and apply that action to the brick (not the scene)
