Recently while making a Siri Shortcut, I discovered something. In open app, I saw an app called Xcode preview. When I ran the shortcut, the Xcode preview app showed a launch screen and crashed. What is this app?

Hi! Last week my app was accepted, but it is not showing up.https://pasteboard.co/JclRwER.png - Ready For Salehttps://pasteboard.co/JclT6jH.png - App Not Available

Hi everyone! Because iOS 14 had a whole new home screen, I wonder if SpringBoard is on iOS 14! Even if it is, is App Library a separate app?

Here is code to make a simple Swift WWDC countdown:import Cocoa let today = Date() let startDate = "2020-06-22" let dateFormatter = DateFormatter()dateFormatter.dateFormat = "yyyy-MM-dd" let finalStartDate = dateFormatter.date(from: startDate)let components = Set<Calendar.Component>([.day, .hour]) print("WWDC20 Will Come on JUNE 22") let daysToDc = Calendar.current.dateComponents(components, from: finalStartDate!, to: today) let printableDays = Int(daysToDc.day!) let printableHours = Int(daysToDc.hour!) print(String(printableDays)+" days " + String(printableHours) + " hours till WWDC2020")

I have an app where there are 2 views, one with a UILabel and another with a UITextField. I would like it so the moment you are done editing the Text Field, the label changes to the TF's value. The text field stores its value in a UserDefaults and when my Label's View loads, it shows the value of the UD key on the label. Again, I would like it so the moment you are done editing the Text Field, the label changes to the TF's value. Below is my Label's View's Controller struct myStruct {     static var money = 0.00 } import UIKit class ViewController: UIViewController {     @IBOutlet weak var moneyLabel: UILabel!     override func viewDidLoad() {         super.viewDidLoad()         let ud = UserDefaults.standard         myStruct.money = ud.double(forKey: "Money")         moneyLabel.text = String(ud.double(forKey: "Money"))              } } My TextField's View's Controller import UIKit class AddMoneyViewController: UIViewController {          let userDefaults = UserDefaults.standard               @IBOutlet weak var TextField: UITextField!          override func viewDidLoad() {         super.viewDidLoad()                  }          @IBAction func TFEditingDidEnd(_ sender: Any) {         userDefaults.set(TextField.text, forKey: "Money")         let moneyAtPoint1 = userDefaults.double(forKey: "Money")         print(moneyAtPoint1)          }      }

Is there any way to have a SpriteKit Game in the TouchBar?

Hi everyone! I am experiencing this issue: This build is using a beta version of Xcode and can’t be submitted. Make sure you’re using the latest version of Xcode or the latest seed release found in What’s New in App Store Connect. I have Xcode 12 beta on my Mac and have archived the app from there. I was able to submit the build for internal testing but it gives me the issue when I try to submit for external testing!

Whenever I run my app on the iPhone SE(2nd Generation) iOS 14.0 Simulator, it shows a loading sign and error message “SpringBoard has quit unexpectedly” Anyone know the issue?

Hello! I am making a game where you can place blocks and I would like to have an undo button to delete the last placed block! How do I do this? My code is here: Please remove .LOG extension from the code ViewController.swift - https://developer.apple.com/forums/content/attachment/2fc14933-2e81-46a2-afc5-abb7fc74e086

Hi Developers! I am going to submit my ARKit app for review on the App Store today, but I am having trouble with my screenshots. I have taken my 6.5 inch screenshots, my 5.8 inch screenshots, and all my iPad screenshots! The problem is: I don't have any 5.5 inch devices! The reason I cannot use simulators is because ARKit is not supported on the Simulator. Please help!

Hi Devs! I think a touchscreen Mac is going to come out soon! Some Evidence: Apple Silicon - With Apple Silicon coming to Mac, Apple could include touch drivers for Mac Control Center - MacOS Big Sur probably has a Control Center so it is easier to change settings on touch Macs Mac Catalyst - The iPad is touchscreen, and Catalyst is all about iPad apps on Mac. Hints for a touch Mac

I would like to build a WidgetKit widget using UIKit, but I know you can only make them in SwiftUI. Are there any workarounds? Could we try to make a storyboard and then add it to the widget like this - https://developer.apple.com/tutorials/swiftui/interfacing-with-uikit?

Hi Devs! I am trying to build a widget for my app MathFlash Fun - https://apps.apple.com/us/app/mathflash-fun/id1502858843, but I am unable to deploy the widget to my iPad and the Simulator!

I have an app made in UIKit with a deployment target of 9.0 which I would like to apply SwiftUI to. I would like my app to use SwiftUI while still being compatible with iOS 9.0 and later. Does anyone know how to achieve this, because SwiftUI is only in iOS 13.0 or later

I am developing an app clip, but I can't get it to launch from a website.
