swiftui

问题 I have a TabView thats using the swiftUI 2.0 PageTabViewStyle. Is there any way to disable the swipe to change pages? I have a search bar in my first tab view, but if a user is typing, I don't want to give the ability to change they are on, I basically want it to be locked on to that screen until said function is done. Here's a gif showing the difference, I'm looking to disable tab changing when it's full screen in the gif. https://imgur.com/GrqcGCI 回答1: Try something like the following

问题 I am creating single selection list to use in different places in my app. Questions: Is there an easy solution I don't know? If there isn't, how can I finish my current solution?

问题 I want to set picker as my inputView for TextField, can I do it with SwiftUI only or I have to use UIKit components with help of framework integration? Code example in UIKit: textField.inputView = UIPickerView() I want to do same, but with SwiftUI's TextField 回答1: As of Xcode 11.4, SwiftUI's TextField does not have an equivalent of the inputView property of UITextField . You can work around it by bridging a UIKit UITextField to SwiftUI, and by bridging a SwiftUI Picker to UIKit. You'll need

问题 I'm trying to create a view in a sheet with multiple "pages". The view holds a @State variable of an enum and I "switch" between pages with if self.page == .text {...} else if self.page == .image {...} else {...} However, when self.page is set while a textfield is active in one of the pages, the app crashes with no clear error message. This seems to work on the simulator but not on a device. Here's the dump: Thread 1 Queue : com.apple.main-thread (serial) #0 0x00000001f6dc702c in
