While I do need to get another HD, I currently have 34.85 GB (12.61 GB purgeable) available. Yet for some reason when I try to run update on Xcode, it says I don't have enough HD space. That's three times the final size of the new Xcode. Is there some way around this?

Below is a simple code patch I use to create a custom button, am new at this. I noticed the text does not appear and am wondering what the proper method is for making the text appear? func makeButton (vControl: ViewController, action: Selector) { let myButtonImage = UIImage(named: "Picture1.png") let imageScale = myButtonImage!.size.width / myButtonImage!.size.height let wwidth = vControl.self.view.bounds.width let button = CreateButton(frame: CGRect(x: 100, y: 100, width: (myButtonImage?.size.width)!/3, height: (myButtonImage?.size.height)!/3)) button.setImage(myButtonImage, for: .normal) button.backgroundColor = .clear button.setTitleColor(.black, for: .normal) button.setTitle("Test Button", for: .normal) button.addTarget(vControl, action: action, for: .touchUpInside) vControl.view.addSubview(button) button.center = vControl.view.center }

I've created a ball, and boxed my game scene. The balls physics settings are: self.physicsBody!.affectedByGravity = true self.physicsBody!.restitution = 1.0 self.physicsBody!.linearDamping = 0 self.physicsBody!.friction = 0.3 self.physicsBody!.isDynamic = true self.physicsBody!.mass = 0.5 self.physicsBody?.contactTestBitMask = bodyMasks.blankMask.rawValue self.physicsBody?.collisionBitMask  = bodyMasks.edgeMask.rawValue self.physicsBody?.categoryBitMask   = bodyMasks.ballMask.rawValue When I box the game scene with: self.physicsBody = SKPhysicsBody(edgeLoopFrom: self.frame) the ball bounces back up as intended. However, if I replace edgeLoopFrom with my own custom borders: yourLine.lineWidth = 5 yourLine.path = pathToDraw yourLine.isUserInteractionEnabled = false yourLine.strokeColor = .clear yourLine.isHidden = false yourLine.zPosition = 10 yourLine.physicsBody = SKPhysicsBody(edgeLoopFrom: pathToDraw) yourLine.physicsBody?.affectedByGravity = false yourLine.physicsBody?.pinned = true yourLine.physicsBody?.categoryBitMask = bodyMasks.edgeMask.rawValue yourLine.physicsBody?.collisionBitMask = bodyMasks.ballMask.rawValue yourLine.physicsBody?.contactTestBitMask = bodyMasks.blankMask.rawValue the ball just comes down with a thud, stops, and doesn't bounce., So am trying to figure out what physics settings I have to give to my custom made edges so that the ball bounces?

I would like to take this sample code override func viewDidLoad() { super.viewDidLoad() let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50)) button.backgroundColor = .greenColor() button.setTitle("Test Button", forState: .Normal) button.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) self.view.addSubview(button) } func buttonAction(sender: UIButton!) { print("Button tapped") } ...and place the code to create the button in another file. So it would look more like this: class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() makeButton(vControl: self) } @objc func buttonAction(sender: UIButton!) { print("Button tapped") } } Of course the main flaw is that I would have to pass a pointer to the function buttonAction. Something like we do in C makeButton(vControl: self, bFunc: &buttonAction) Have Googled a lot but can't seem to find the way to do this. How do I set up the makeButton page to recieve this? func makeButton (vControl: ViewController, bFunc: ???) What would the ??? be in reality? thanks

I have a very simple app. All SKSpriteNodes, myBall, myBlue, and myRed. Only myBall moves, affected by gravity, and bounces off of different objects (myRed and myBlue). What I can't figure out is how to make myBall bounce harder or softer depending on which body it hits? I hav been playing with the density of all the objects, but it doesn't seem to make any difference? Is there some property I am unaware of? Or are there other methods?

I have an SkSpriteNode (ball) in a box. Gravity is set to false, otherwise it has an SkPhysicsBody to bounce off of walls. Is there a method to give the ”ball” an initial push in a specified direction and velocity/strength wise?

I know it's uncool to ask vague questions here, but what do they call it when you create a world and follow it with a camera in Swift? Like an RPG? Like Doom? I want to try and learn that now. And more importantly can it be done without using the Xcode scene builder? Can it be done all via code? Thanks, as always. Without the forum I would never have gotten much farther than "Hello World!"

In my app, I have greyBars and one border bar. The border bar keeps the greyBars from falling off the screen. Only one greyBar is used at a time. When it is completely filed with colored gems, a new bar is created and brought up from the bottom of the screen, with the code below. The result I want is that the new bar, the one with all white diamonds pushes up the old bar and the new bar remains on the bottom. You can see by the screenshot that somehow the new bar ended up on top, even though it was coming from the bottom. I slowed down the duration of the greyBar's movement to see what was going wrong. While the two greyBars do clash with each other, the new one (the one on the bottom) ends up pushing THROUGH the top bar. My assumption was that the new greyBar would just push up the old bar(s), and remain on the bottom. Is there some "solidity" type property that I am missing? myGreyBar[0].physicsBody?.categoryBitMask = bodyMasks.greyBarMask.rawValue myGreyBar[0].physicsBody?.contactTestBitMask = bodyMasks.blankMask.rawValue myGreyBar[0].physicsBody?.collisionBitMask = bodyMasks.greyBarMask.rawValue myGreyBar[0].isHidden = false; myGV.gameScene?.addChild(myGreyBar[0]) let moveAction = SKAction.move(to: CGPoint(x:(myGV.safeSceneRect.width/2) - (size.width/2), y: (myGemBase?.size.height)! + (myGV.border?.size.height)! + 200), duration: 10.0) myGreyBar[0].run(moveAction, completion:{myGreyBar[0].physicsBody?.collisionBitMask = bodyMasks.borderMask.rawValue|bodyMasks.greyBarMask.rawValue})

I have an SKSpriteNode with an SKAction being run on it: theGem!.run(premAction, completion: {theGem!.run(repeatAction)}) Can't seem to find out the proper steps to run another action, such as: theGem.run(endsequence, completion: {theGem.removeAllActions(); theGem.run(stopAction)}) Should I stop the previous action first? Is there a way to turn the repeat part off so that the first SKAction ends smoothly?

I handled everything through touchesEnded. Was curious if I could hand off the call to touchesEnded from touchesCancelled?

Just curious why I get touchesCanceled even after I process: @objc func tappedView(_ sender:UITapGestureRecognizer) It's requiring a lot of extra coding to determine a real cancel vs I just got a tap.

I was looking to find a way to find out if my SKSpriteNode with an SKPhysicsBody is in motion. I create a box, raise it above the bar, then set the bar and box masks to collide. The bar is pinned, but would love to know when the box stops bouncing.

I am using debug labels so I know when I get any touchesBegan, touchesMoving, touchesEnded, and touchesCanceled. I get everything I expect, touchesBegan, touchesMoved, and touchesEnded. However, it would appear that if I barely, just barely move an SKSPriteNode, I get a touchesCanceled instead of touchesEnded. Even thought the call right before is touchesMoved. Is this as intended? Is there some threshold you have to reach to get an ended instead of a canceled? And if so, can I see and change it? Thanks More than glad to put my code, tho not sure how that would change anything.

While debugging I would like to get a specific subclass's property. So far I can do this: if let myPeg = getTargetSlot(node: node, location touchLocation){           print (myPeg.index)             } Is it possible to write it in one line? Something like this? print ("\(getTargetSlot(node: node, location touchLocation).index") Because if there is a way, I cannot figure out the syntax. Thanks

I know this is a silly question, but I just want to be safe. I have multiple subclasses of SKSpriteNode in my app. In touchesBegan I am looking for a specific type, MyPeg. I just want to make sure that the code below fails if the node is not a MyPeg. I have this fear that if another of my subclasses is the same size, or too similar, or even has the same variables that I might get a positive. override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?){ super.touchesBegan(touches , with:event) guard let touch = touches.first else { return } let location = touch.location(in: self) let touchedNodes = self.nodes(at: location) for theNode in touchedNodes{ if let node = theNode as? MyPeg{
