![]() where we can drag and drop the images for that specific attribute. The PhotosPicker uses Transferable, which is a new SwiftUI protocol for transferring data between apps and extensions.ĭuring Apple's demo it is suggested that you can specify the type as Image and that loadTransferable(type:) will decode and return a respective Image instance. How to take advantage of Swift and SwiftUI to create insanely great apps for iPhones. ![]() The load operation could also fail if an error was encountered, for example, when the picker was trying to download data from iCloud Photos but the device was not connected to the internet. Please note that asset data won't be loaded immediately. Load the asset data on demand with PhotosPickerItem.loadTransferable Here is an example of using PhotosPicker to select a single image by clicking on an image. There are various initializers for PhotosPicker ,so I encourage you to read through the documentation. Use PhotosPicker view to obtain one or more instances of PhotosPickerItem Load the asset data on demand with PhotosPickerItem.loadTransferable.Use PhotosPicker view to obtain one or more instances of PhotosPickerItem.You don't need to worry about what the picker UI should be, so you just can focus on making your app better.įrom a developer's perspective, there are two steps The picker will automatically choose the best layout depending on the platform, your app's configuration, and available screen space. The picker runs out of process, so your app doesn't need to request any library access to use it. You no longer have to use UIViewControllerRepresentable to wrap either PHPickerViewController or its older version UIImagePickerController. The new SwiftUI PhotosPicker API is available on all picker-supported platforms: Open KuchiApp.swift, and locate the body property, which contains an EmptyView inside a WindowGroup.In this blog post I'll show you how to use the new SwiftUI PhotosPicker API that was announced in the WWDC22 session What's new in the Photos picker. Changing the root viewīefore doing anything, you need to configure the app to use the new WelcomeView as the starting view. ![]() You now have a blank new view to start with. Then type WelcomeView.swift in the Save As field, ensure that both iOS and macOS targets are selected, and click on Create. In the popup that comes next, choose SwiftUI View, then click Next. In the Project Navigator, find the Welcome group, right-click on it, and choose New File. If you build and run, all you’ll get is a blank view. There’s almost no user interface only some resources and support files. Enjoy! Getting startedįirst, open the starter project for this chapter, and you’ll see that it’s almost empty. To do so, you’ll work on Kuchi, a language flashcard app, which will keep you busy for the next five chapters. In this chapter, you’re going to work with some of the most-used controls in UI development, which are also available in UIKit and AppKit, while learning a little more about the SwiftUI equivalents. Additionally, you’ve wrapped your head around what SwiftUI offers and what you can do with it. In the previous chapters, you’ve only scratched the surface of SwiftUI and learned how to create some basic UI. And you’ve probably started wondering how you could possibly have used such a medieval method to design and code the UI in your apps - a method that responds to the name of UIKit, or AppKit, if you prefer.
