A couple of weeks ago, I made my first litte Xcode project using SwiftUI.The ContentView is just a simple TabbedView using binding/state variable to select a tab.Code look like this:import SwiftUI struct ContentView : View { @State var selection: Int = 1 var body: some View { TabbedView(selection: $selection) { Text(Tab 1!).tabItemLabel(Text(Tab 1)).tag(1) Text(Tab 2!).tabItemLabel(Text(Tab 2)).tag(2) } } }Back then, when I first made the project, it was running fine.Now, it just crashes consistently with the log:dyld: lazy symbol binding failed: Symbol not found: _$s7SwiftUI5StateV13delegateValueAA7BindingVyxGvg Referenced from: /Users/asl/Library/Developer/Xcode/DerivedData/aaa-byucivzkosyehgdhjnjxicgrjnbi/Build/Products/Debug/aaa.app/Contents/MacOS/aaa Expected in: /System/Library/Frameworks/SwiftUI.framework/Versions/A/SwiftUIdyld: Symbol not found: _$s7SwiftUI5StateV13delegateValueAA7BindingVyxGvg Referenced from: /Users/asl/Library/Developer/Xcode/DerivedData/aaa-byucivzkosyehgdhjnjxicgrjnbi/Bu

I'm uploading a new SwiftUI app to Testflight. I use Combine to get data from my own REST API. I got an email from Apple saying that i'm using non-public APIs.We identified one or more issues with a recent delivery for your app, Tailosive Hub 1.0 (30). Please correct the following issues, then upload again. ITMS-90338: Non-public API usage - The app references non-public symbols in Tailosive Hub: _$s7Combine18PassthroughSubjectC4sendyyxF, _$s7Combine18PassthroughSubjectCACyxq_Gycfc, _$s7Combine18PassthroughSubjectCMa, _$s7Combine18PassthroughSubjectCyxq_GAA9PublisherAAMc.I'm not using any private APIs and following public documentations.Thanks in advance!

I have beel fiddling with SwiftUI and it has taken up a huge amount of CPU %. Has anybody else experienced this? It it takes forever to build. I think I have it confused.My Xcode is shut down, but I still have two swift processes running at 98%.Something wrong here....

I have a Tinder-like Vstack card that swipes left and right. The VStack contains an Image and a TextField below it. I want to drag the Image and have it drag the whole VStack, TextField included. It does that. However, the TextField also drags the whole VStack. I only want the Image to drag and have the textfield work as a textfield. Here is the code for the VStack.return VStack { VStack { Image(food) .resizable() .aspectRatio(1.0, contentMode: .fit) .clipShape(RoundedRectangle(cornerRadius: 50)) TextField(Leave a comment, text: $comment, onEditingChanged: { if $0 { self.kGuardian.showField = 0 } }) { commentText = self.comment } .padding() .background(GeometryGetter(rect: $kGuardian.rects[0])) .background(Color(red: 239.0/255.0, green: 243.0/255.0, blue: 244.0/255.0, opacity: 1.0), cornerRadius: 10.0) } .padding() .shadow(color: Color.black, radius: 15, x: 2, y: 2) .offset( x: viewState.width + dragState.translation.width // y: viewState.height + dragState.translation.height ) // .animation(.basic(duration:

I have a textfield set in a VStack. Everything is as it should be except that the keyboard is no longer showing up. Where did I mess up? How can I get the keyboard to show again?return VStack { Image(food) .resizable() .aspectRatio(1.0, contentMode: .fit) .clipShape(RoundedRectangle(cornerRadius: 50)) .gesture(longPressDrag) .padding() .offset(y: kGuardian.slide).animation(.basic(duration: 1.5)) .shadow(color: Color.black, radius: 15, x: 2, y: 2) TextField(Leave a comment, text: $comment, onEditingChanged: { if $0 { self.kGuardian.showField = 0 } }) { commentText = self.comment } .padding() .background(GeometryGetter(rect: $kGuardian.rects[0])) .background(Color(red: 239.0/255.0, green: 243.0/255.0, blue: 244.0/255.0, opacity: 1.0), cornerRadius: 10.0) } .padding() .shadow(color: Color.black, radius: 15, x: 2, y: 2) .offset( x: viewState.width + dragState.translation.width ) .presentation($showAlert) { Alert(title: Text(User commented on this photo!), message: Text(commentText), primaryButton: .default(Text(O

Hello,Is it possible to access the Now Playing view on watchOS with SwiftUI? Also, how do ensure that the information from MPNowPlayingInfoCenter appear? I have provided the metadata, but no Now Playing view appear.

Is there an equivalent of “touchUpInside” in SwiftUI?In UIKit, it was very easy to look for a touchUpInside event.With SwiftUI, we can attach a “tapAction”, but this will require re-training users to always be “quick and decisive” in their actions.Any hope for a more deliberative, slow-fingered user?

I am unable to use more than one .presentation in a SwiftUI view. Below is a simple example.import SwiftUI struct ContentView : View { @State private var showingAlert = false @State private var showSavedAlert = false var body: some View { VStack { Text(Hello World) Button(action: { self.showingAlert = true }) { Text(Save) } Button(action: { self.showSavedAlert = true }) { Text(Save2) } } .presentation($showingAlert) { Alert(title: Text(Save File?), message: Text(Do you want to save?), primaryButton: .default(Text(Save)) { }, secondaryButton: .cancel()) } .presentation($showSavedAlert) { Alert(title: Text(Another Save File?), message: Text(Do you want to save?), primaryButton: .default(Text(Save)) { }, secondaryButton: .cancel()) } } } #if DEBUG struct ContentView_Previews : PreviewProvider { static var previews: some View { ContentView() } } #endifDoes anybody have a workaround?

I'm working with Combine in Xcode 11 beta 3 and IOS 13 beta 3, and I'm hitting an odd compiler error. I'm not sure if I'm not specifying something sufficiently or completely, or if this is a error with the swift compiler not being able to correctly infer what it needs to know.I have a UIImageView reference, and I'm making my code is a Combine pipeline that retrieves a URL to populate that imageview and then (tries to use) assign to set it into place.The short form of this code (full code at https://github.com/heckj/swiftui-notes/blob/master/UIKit-Combine/ViewController.swift#L167-L231):URLSession.shared.dataTaskPublisher(for: URL(string: firstUser.avatar_url)!) // ^^ this hands back (Data, response) objects .handleEvents(receiveSubscription: { _ in DispatchQueue.main.async { self.activityIndicator.startAnimating() } }, receiveCompletion: { _ in DispatchQueue.main.async { self.activityIndicator.stopAnimating() } }, receiveCancel: { DispatchQueue.main.async { self.activityIndicator.stopAnimating() } })

What is the SwiftUI equivalent to returnKeyType? How do we implement it?

Hi,I am developing an app that has 5 buttons on the screen. Tapping on a button would take you to another viewController.How would I do this in SwiftUI?Here's my code:import SwiftUI struct MainSwiftUI : View { var body: some View { VStack { Button(action: {}) { // Text(Pick One) .cornerRadius(40) } .background(Color .red) Button(action: {}) { // action Text(Pick Two) .cornerRadius(40) } .background(Color .green) Button(action: {}) { // action Text(Pick Three) .cornerRadius(40) } .background(Color .blue) Button(action: {}) { // action Text(Disclaimer) .cornerRadius(40) } .background(Color.black) Button(action: {}) { // action Text(About) .cornerRadius(40) } .background(Color.black) } } } #if DEBUG struct MainSwiftUI_Previews : PreviewProvider { static var previews: some View { Group { MainSwiftUI() .previewDevice(Apple Watch Series 4 - 40mm) MainSwiftUI() .previewDevice(Apple Watch Series 4 - 44mm) } } } #endif
