问题 I'm trying to setup Sign-in with Apple with Xcode (Beta 11.0 beta 6). Works great on simulator, but when I run it on my iPhone (iOS 13.1), I don't get the same display. On Simulator: On iPhone: This is how I call my "Sign in with Apple": - (IBAction)signInWithApple:(id)sender { if (@available(iOS 13.0, *)) { ASAuthorizationAppleIDProvider *appleIDProvider = [[ASAuthorizationAppleIDProvider alloc] init]; ASAuthorizationAppleIDRequest *request = [appleIDProvider createRequest]; request

问题 The following code gets the keyboard height when the keyboard is displayed and moves the button by the keyboard height. This movement is performed in the same way at the transition source (ContentView) and the transition destination (SecibdContentView), but the button does not move at the transition destination. How can I make the buttons move the same on multiple screens? import SwiftUI struct ContentView: View { @ObservedObject private var keyboard = KeyboardResponder() var body: some View

For example I need a ' @PublishedUserDefault var isLogedIn '.

问题 Playing around with examples out there. Found a project that had a class that was a bindableobject, it didn't give any errors. Now that Xcode 11 beta 4 is out, I'm getting the error: Type 'UserSettings' does not conform to protocol 'BindableObject' It has a fix button on the error, when you click on that, it adds typealias PublisherType = <#type#> It expects you to fill in the type. What would the type be? class UserSettings: BindableObject { let didChange = PassthroughSubject<Void, Never>()

问题 XCode: 11.1 OS: 10.15 Test device: iPhone 5s, iOS: 12.4.2 Hi guys, I made a stupid mistake to immediately upgrade Xcode and MacOS, without waiting for a later stable version. Anyway, if I made changes in my code, for example adding a NSLog() line, this addition is not updated on the app in my test device. To make it work, I have to uninstall the app from the test device, and reinstall it by running the code from Xcode. This happens every time I make changes in code. I have to delete the app

It only crashes on my iPhone 6s iOS 13 beta 6 Xcode beta 5 That's my basic code: class NetworkManager: ObservableObject { } struct ContentView : View { @ObservedObject var networkManager: NetworkManager = NetworkManager() var body: some View { Text("Hi Stack") } } #if DEBUG struct

问题 I'm using Xcode11 Beta as IDE and Swift. Below is my code, my code can work well on Xcode10.3, but it can't work on Xcode11. When I call the function SecKeyCopyKeyExchangeResult(), the stack always return an error, "kSecKeyKeyExchangeParameterRequestedSize is missing", but it's okay on Xcode10.3.

问题 I am following along with the session from WWDC2019 here : https://developer.apple.com/videos/play/wwdc2019/216/ I have the following code working for creating a TabbedView using SwiftUI : //Section1 | ContentView (mine)--------------------------- import SwiftUI struct ContentView : View { var body: some View { NavigationView { TabbedView(selection: .constant(1)) { PlaceForm().tabItemLabel(Text("Tab1")).tag(1) FavoritesForm().tabItemLabel(Text("Tab2")).tag(2) } } } } #if DEBUG struct
