![]() SwiftUI continues to expand to cover many more existing UI components, like half sheets that slide up over a main view when a user wants to see more information or share sheets that let users take advantage of all the Share Extensions installed on their device. Swift Charts also supports VoiceOver to deliver information to all your users. Swift Charts uses the compositional syntax of SwiftUI to create views with many possibilities, from line and bar charts to advanced types like stream graphs. Visualize data with highly customizable charts that look and feel great across all Apple platforms. These custom cells fully integrate with UIKit, providing all the expected functionality, such as swipe actions and cell backgrounds. Now you can easily write custom UICollectionView cells using the declarative syntax of SwiftUI. SwiftUI is designed to work alongside other interface frameworks. Build menu bar extras with SwiftUI to provide access to your app’s functionality from anywhere on Mac. Support for windowing on macOS is improved with single, unique windows and new modifiers for window position, size, and resizability. And SwiftUI now includes ViewThatFits, which lets you specify multiple variations of a given view and lets SwiftUI automatically choose the one that best fits in the available space. There’s also a new low-level custom Layout API, giving you full control to build exactly the layout your app needs. ![]() In addition to VStack and HStack, SwiftUI now offers a new Grid API to simultaneously align views both horizontally and vertically. Advanced layout controlīuild advanced, reusable layouts to power the design of your app. 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.Leverage programmatic control over your app’s navigation behavior to set its launch state, manage transitions between size classes, respond to deep links, and more. 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). 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). ![]()
