Hi, I have a toolbar and a share button on the left side. The button isn't showing up on the canvas, but does show when the app is run in the simulator or a device. Is this normal behavior or a bug? This is a test button so please forgive the print statement. Here's the code:         {           ToolbarItem(placement: .bottomBar)           {             Button(action: {               print ("Button Pressed!")             }               ){                              Image(systemName: "square.and.arrow.up")             }             }         }

Hi, I am looking for opinions on the best way to handle a problem I'm having. My client wants his app to show a list of math tables, such as 1+1 = 2, 2+2 = 4, and so on. I have a list view with said tables in an array, which I manually have to input in. He wants the list to go from 1 to 20. I'd assume that I would need some sort of for....next loop, but how would I show that in a list? Thanks for any help you can give. This is what I have so far: import SwiftUI import UIKit struct ATables: View {      var tables = ["Temporary","1 + 1 = 2","2 + 2 = 4"]        var body: some View {                NavigationView {               List {                  ForEach(self.tables, id: \.self) { show in                      HStack {           Image(systemName: "arrow.right")             .resizable()             .frame(width: 30, height: 20, alignment: /*@START_MENU_TOKEN@*/.center/*@END_MENU_TOKEN@*/)           Text(show)             .font(.custom("Chalkboard", size: 50))           }         }       }.navigationBarTitle(Text("Addition Tables (1 - 20)"))           .navigationBarTitleDisplayMode(.inline)     } } struct ATables_Previews: PreviewProvider {     static var previews: some View {         ATables()     } } }

Okay, I give up. I am making a Flash card game where the app will randomize two numbers, then the user would enter the answer. The app will then tell the user if he/she is correct. But I cannot seem to figure out how to get it to add two numbers and check if the user's correct or not. Any help is greatly appreciated! Here's the code: import UIKit import AVFoundation import Foundation class YouSolveIt: UIViewController {      @IBOutlet var topProblem: UILabel!   @IBOutlet var botProblem: UILabel!   @IBOutlet var youAnswer: UITextField!   @IBOutlet var actualCard: UIImageView!      let speakit = AVSpeechSynthesizer()      var problem1 = Int(0)   var problem2 = Int(0)   var answer = 0      var ranA = 0   var ranB = 0     override func viewDidLoad() {         super.viewDidLoad()       // Load Flash Card image:       actualCard.image = UIImage(named: "FlashCard")              solveitproblem()   }      func solveitproblem()   {          let ranA = Int(arc4random_uniform(UInt32(9)))     let ranB = Int(arc4random_uniform(UInt32(9)))          topProblem.text = String(ranA)     botProblem.text = String(ranB)     youAnswer.text = String(answer)          let speakProblem = AVSpeechUtterance(string: "What is \(topProblem.text! + ", plus ," + botProblem.text!)")      speakit.speak(speakProblem)   }      @IBAction func btncheckAnswer(_ sender: Any)   {          if (ranA) + (ranB) == answer     {            correctAnswer()          }          else {              wrongAnswer()     }           }      func correctAnswer()   {     let right = [1,2,3,4,5]          let randomIndex = Int(arc4random_uniform(UInt32(right.count)))          switch(randomIndex)     {       case 1:         let speakRight = AVSpeechUtterance(string: "That is correct")         speakit.speak(speakRight)         youAnswer.text = ""         solveitproblem()                case 2:         let speakRight = AVSpeechUtterance(string: "You're right!")         speakit.speak(speakRight)         youAnswer.text = ""         solveitproblem()                case 3:         let speakRight = AVSpeechUtterance(string: "Correct!  Let's try.")         speakit.speak(speakRight)         youAnswer.text = ""         solveitproblem()                case 4:         let speakRight = AVSpeechUtterance(string: "You are right!  Next Try.")         speakit.speak(speakRight)         youAnswer.text = ""         solveitproblem()                case 5:         let speakRight = AVSpeechUtterance(string: "Great answer!")         speakit.speak(speakRight)         youAnswer.text = ""         solveitproblem()                default:         let speakRight = AVSpeechUtterance(string: "Very good!")         speakit.speak(speakRight)         youAnswer.text = ""         solveitproblem()     }   }      func wrongAnswer()   {     let wrong = [1,2,3,4,5]          let randomIndex = Int(arc4random_uniform(UInt32(wrong.count)))          switch(randomIndex)     {       case 1:         let speakRight = AVSpeechUtterance(string: "That is wrong")         speakit.speak(speakRight)                case 2:         let speakRight = AVSpeechUtterance(string: "You're wrong, please try again.")         speakit.speak(speakRight)                case 3:         let speakRight = AVSpeechUtterance(string: "No, that's not it.  Please try again.")         speakit.speak(speakRight)                case 4:         let speakRight = AVSpeechUtterance(string: "No")         speakit.speak(speakRight)                default:         let speakRight = AVSpeechUtterance(string: "I'm sorry, no.  Please try again.")         speakit.speak(speakRight)   } } }

Hi, I'm trying to make a small text editor. Everything works except I need the background a different color. But the standard way to do it with 'ZStack' doesn't work? Any ideas?

Hi, I'm currently developing an Apple Watch app with Swift and Storyboards. The main screen consists of three buttons going to three different view controllers. When I go to one view controller, it doesn't display the normal back "" button at the top-left corner, even though it works. I tried this with an older project, with a similar setup and it works as it should. I have no code to show because it works like it should. It seems to be with the storyboard. Anyone else have this problem? Thanks, Dan Uff The code is exactly the same in both projects, with

Hi,How would I go about using the standard WebKit delegates in SwiftUI, such as:func webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) { activityView?.startAnimating() self.title = "Loading...." }Here's what I have so far:import SwiftUI import UIKit import Foundation import WebKit struct Support: View { var body: some View { NavigationView { VStack { WebView(request: URLRequest(url: URL(string: "https://www.connectingpeoplesoftware.com/iossupport")!)) }.navigationBarTitle(Text("Support")) } } struct WebView: UIViewRepresentable { let request: URLRequest func makeUIView(context: Context) -> WKWebView { return WKWebView() } func updateUIView(_ uiView: WKWebView, context: Context) { uiView.load(request) } } struct Support_Previews: PreviewProvider { static var previews: some View { Support() } } }Thanks in advance,Dan

Hi, I have been trying to change the default color of the NavigationView in the AppDelegate file and am unable to. Is it the code, or me? Using Xcode 13, Beta 1. I got the code from hackingwithswift.com.

Hi, I added an Apple Watch target to an existing app using SwiftUI and Xcode 13 (13A233) and the Canvas shows the first view controller correctly (an Apple Watch) but when I add additional VCs, the canvas shows an iPhone. I recreated the additional VC making sure I had WatchOS selected and got the same thing. Is anyone else having this problems with this? Any work arounds? Thanks, Dan Uff

Hi, I have a small Apple Watch game that someone downloaded and liked a lot. That same individual asked me to make a Mac version of the same app, which I am willing to do. Should I add the app to the current Apple Watch version, or make a stand alone version? Thanks, Dan Uff

Hi, When I try to install a app that I want to test on an iPhone 13, I get the following error: ` Showing All Messages The file "/Users/danuff/Documents/CPS/iOS/iOS 15/Projects (Current)/iPhone : iPad/SwiftUI/General/DVP/DVP/DVP.entitlements" could not be opened.

The app is not installed on the actual device, but it does work on the Simulator.' It worked fine the other day. Thanks, Dan Uff
