Run two SKActions at once

Use a group action.

From sprite kit programming guide:

A group action is a collection of actions that all start executing as soon as the group is executed. You use groups when you want actions to be synchronized

SKSpriteNode *wheel = (SKSpriteNode*)[self childNodeWithName:@"wheel"];CGFloat circumference = wheel.size.height * M_PI;SKAction *oneRevolution = [SKAction rotateByAngle:-M_PI*2 duration:2.0];SKAction *moveRight = [SKAction moveByX:circumference y:0 duration:2.0];SKAction *group = [SKAction group:@[oneRevolution, moveRight]];[wheel runAction:group];

A example in Swift would be:

    let textLabel = SKLabelNode(text: "Some Text")    let moveTo = CGPointMake(600, 20)    let big = SKAction.scaleTo(3.0, duration: 0.1)    let med = SKAction.scaleTo(1.0, duration: 0.3)    let reduce = SKAction.scaleTo(0.2, duration: 1.0)    let move = SKAction.moveTo(moveTo, duration: 1.0)    let fade = SKAction.fadeOutWithDuration(2.0)    let removeNode = SKAction.removeFromParent()    let group = SKAction.group([fade, reduce])    let sequence = SKAction.sequence([big, med, move, group, removeNode])    self.addChild(textLabel)    textLabel.runAction(sequence)
