There's a closely related bug which prevents the value of the SwiftUI View's property (if it has one) from correctly updating in response to its TextField being tapped - even when the above workaround is successfully used to make the on-screen keyboard show when that TextField is tapped - providing that that SwiftUI View is the top-level View in the Preview. MacBook Pro (Retina, 13-inch, Late 2013) running macOS Big Sur Version 11.6Įdit: I've discovered a closely related bug.How often will you probably need to use the above workaround?Īfter every full-build, but probably not after every partial re-build, of the SwiftUI Live Preview. Bring the Xcode Previews app back into the foreground.Send the Xcode Previews app into the background (such as by swiping up from the bottom of the screen to view the App Switcher).Workaround for Live Preview running in Xcode Previews app on physical iPhone device It is obviously not intended that this works, and it may stop working at any time in the future. The area is responsive to clicks and all the keys work, but the keyboard itself does not seem to render. Once the setting is in effect, focusing on a text input field will cause the software keyboard area to appear. This command will not affect any simulators running in the iOS Simulator app, but will cause all previews to stop working until Xcode relaunches the simulated devices, and may cause Xcode's UI to temporarily behave strangely (or at least the effects were temporary when I tried it in Xcode 12.4). You can also try executing this command in a terminal: xcrun simctl -set ~/Library/Developer/Xcode/UserData/Previews/Simulator\ Devices shutdown all The easiest way to do this is to restart Xcode or to switch to a different simulated device (such as from iPhone 11 to iPhone 12). Worse, flipping the setting in the Simulator app is not enough by itself you have to force the preview to fully reload the underlying simulator it's using. The keyboard will only appear in "Live Preview" mode and with this setting disabled, and Xcode will instantly reset the setting as soon as it detects any direct keyboard input while the preview has focus (and the Simulator app will not reflect this reset, so to do it again you'll have to toggle it twice). dynamicIsland(.It turns out this setting is (very subtly) tied to the "Connect Hardware Keyboard" preference in the iOS Simulator app (found in the menu bar as I/O → Keyboard → Connect Hardware Keyboard). Need to provide a set of live activity attributes and a set of states.Basically the same api as for timeline provider widgets.Useful for fine tuning your transitions.Pressing the 'pin' button in the upper left of the canvas will allow you to change code files without losing your canvas.Clicking the 'play' button under the preview will animate between timeline states.Let second = first.fillSlice(at: 1, with: ) For example, you can set a starting orientation for the device that you’re previewing on.support passing one or more configuration traits as a variadic argument list.The return value is the place to attach modifiers that provide data through the environment, eg.if you are working on a view that always appears in a list, you can return a populated list view) For Xcode 12.0 and later help, see Xcode in Apple Developer Documentation. but it doesn't have to be - you can return your view embedded in any other views you need to give the view a broader context (eg. Preview layouts in different device configurations. For SwiftUI, just return any view that you're working on.Views can come from SwiftUI, UIKit, or AppKit. When you create a custom View with SwiftUI, Xcode can display a preview of the views content that stays up-to-date as you make changes to the views code. There are two (2) main kinds of content you can preview Before editing the iOS platform code in Xcode, first make sure that the code has been built at least.
