Hello, I am making a RealityKit app where a ball goes and hits some stones, and then goes back to its original position. However, in moving back the ball always tilts a little and sometimes even goes backwards or in other directions! I add my entities in these lines of code: stoneEntity!.scale = [5, 5, 5] anchor.addChild(stoneEntity!) stoneEntity!.transform.translation = SIMD3<Float>(anchor.position.x, anchor.position.y, anchor.position.z) stoneX = stoneEntity!.position.x stoneY = stoneEntity!.position.y stoneZ = stoneEntity!.position.z stoneEntity?.generateCollisionShapes(recursive: true) // Add ball entity anchor.addChild(ballEntity) ballEntity.transform.translation = SIMD3<Float>(anchor.position.x, anchor.position.y, anchor.position.z + 1) ballEntity.generateCollisionShapes(recursive: true) ballEntity.physicsBody = PhysicsBodyComponent(massProperties: PhysicsMassProperties.default, material: PhysicsMaterialResource.default, mode: .kinematic) ballEntity.collision = CollisionComponent(shapes: [.generateSphere(radius: 0.1)], mode: .default, filter: .default) ballEntity.physicsBody?.isTranslationLocked = (true, true, false) view.scene.addAnchor(anchor) And move my ball back in the code: ballEntity.transform.translation = SIMD3<Float>(0, 0, 1) If anyone has any ideas please could you let me know ASAP? Thank you!

Hello, When I try to install the iPadOS 17 public beta, my 32GB iPad says that it needs 13GB free to install the update! Is there a way to update to the beta without freeing up so much space? This is my main iPad so I don't want to reset it, but can I do it using Finder etc? Bye!

Hi. I am making an app with a background image, but that does not take up the full screen on Pro Max iPhones, so I am setting a background color behind the image. Surprisingly, the background color is not showing up. Here is the code of the View: struct IntroView: View {     @StateObject var viewRouter: ViewRouter     var body: some View {         ZStack {             Color("AccentColor").edgesIgnoringSafeArea(.all)             Image("GameStart")             VStack {                 Text(""" The NS Labs app is a placeholder to not show confidential app name """                 ).font(.system(size: 20)).frame(width: UIScreen.screenWidth, height: 250).foregroundColor(Color(.systemBlue)) Text(""" Welcome to the NS Labs App """ ).font(.system(size: 20)).frame(width: UIScreen.screenWidth, height: 200).foregroundColor(Color(.systemBlue))                 Text("Click Let’s Go to start using the NS Labs app!").font(.system(size: 20)).frame(width: UIScreen.screenWidth, height: 200).foregroundColor(Color(.systemYellow)).padding(.bottom, 20)                 Button(action: {                     viewRouter.currentPage = .page2                 }) {                     Text("Let's Go!").foregroundColor(.white).font(.system(size: 34)) }.frame(width: 200, height: 70).background(Color.yellow).cornerRadius(12)             }         } } }

Hi. I am trying to make an app to control a robot.

Hi! I am making an app where you connect to the device and then it takes you to a Device Home view. I have gotten the connection to work, but how can I redirect to the Device Home view? Here is the SwiftUI code for the button: swift Button(action: { let clientID = "Momo-iOS-"+String(Int.random(in: 0..100)) let mqtt = CocoaMQTT(clientID: clientID, host: "192.168.1.26") mqtt.connect() }) { ZStack { RoundedRectangle(cornerRadius: 100).fill(Color.yellow).frame(width: 240, height: 80)   Text("Connect").font(.system(size: 26)).foregroundColor(.white)   } }

Because if iOS 14 expedited review, will apple review my app on the weekend?

Hi! I have a Cloud Firestore database set up and I am trying to make a SwiftUI view which grabs data from houseId(a key in the database) and puts it on a label. When I try, it says Type 'Void' cannot conform to 'View'; only struct/enum/class types can conform to protocols Here is my code: import SwiftUI import MapKit import Contacts import Firebase struct BirdhouseView: View {     @State private var region = MKCoordinateRegion(   center: CLLocationCoordinate2D(latitude: 25.7617, longitude: 80.1918), span: MKCoordinateSpan(latitudeDelta: 10, longitudeDelta: 10)     )     var body: some View {                  let db = Firestore.firestore()                  var houseId = "bluebirdsample"         let housesRef = db.collection("houses").document("\(houseId)")                  housesRef.getDocument { (document, error) in             if let document = document, document.exists {                 let dataDescription = document.data().map(String.init(describing:)) ?? "nil"                 print("Document data: \(dataDescription)")             } else {                 print("Document does not exist")             }         }                  ScrollView {             VStack {                 Text("Bluebird House").foregroundColor(Color.yellow).font(.system(size: 40))                 Image(uiImage: UIImage(named: "sample_house")!).resizable().frame(width: 290, height: 190, alignment: .center).padding()                 Text("A super-cute birdhouse in Irvine Terrace Park!!").padding().foregroundColor(Color.yellow)                 Divider()                 HStack {                     Image(uiImage: UIImage(named: "sample-user")!).resizable().clipShape(Circle()).frame(width: 60, height: 60)                     Text("Beep Boop").font(.system(size: 24)).bold()                 }                 Divider()                 Button(action: {                     let url = URL(string: "http://maps.apple.com/maps?saddr=&daddr=\(33.5958557),\(-117.8806124)")                     UIApplication.shared.open(url!)                 }) {                     Text("Get Directions in Maps!")                 }                                  Map(coordinateRegion: $region).frame(width: UIScreen.main.bounds.size.width, height: 400)         }     }     } } struct BirdhouseView_Previews: PreviewProvider {     static var previews: some View {         BirdhouseView()     } }

Hi Devs! I have my Firestore database set up and I want to have a reusable SwiftUI view for it. I asked a question about this and someone said use ObservableObject. I surfed the web and could not find any tutorials. I would like it so my view's title changes to a value from the database. This is the code to read the database: let docRef = db.collection("houses").document("\(houseId)")   docRef.getDocument { (document, error) in             if let document = document, document.exists {                 let dataDescription = document.data().map(String.init(describing:)) ?? "nil"                 print("Document data: \(dataDescription)")                 self.title = dataDescription                          } else {                 print("Document does not exist")             } } How can I make dataDescription the text of a label?

Hi. I have a project which requires 2 Swift Packages to be installed. I want to install these packages without opening Xcode, like CocoaPods. In CocoaPods, you can do pod 'Package', '~> 3.0' in a Podfile. What is the SwiftPM equivalent to that?
