How to create grid of square items (for example like in iOS Photo Library) with SwiftUI? I tried this approach but it doesn't work: var body: some View { List(cellModels) { _ in Color.orange.frame(width: 100, height: 100) } } List still has UITableView style: One of the possible solutions is to wrap your UICollectionView into UIViewRepresentable . See Combining and Creating Views SwiftUI Tutorial, where they wrap the MKMapView as an example. By now there isn’t an equivalent of UICollectionView in the SwiftUI and there’s no plan for it yet. See a discussion under that tweet . To get more

问题 In the same theme as this post: iOS 13 - UIPopoverPresentationController sourceview content visible in the arrow I have a UITableViewController instantiated from the Storyboard. I'm presenting it in a UIPopoverViewController. Depending on orientation I either have a side missing or the top missing and the content of the _UITableViewHeaderFooterViewBackground scrolls 'through' the arrow. What's wrong: These are when it's on the top, but if it presents on the side then the whole side EDIT: I AM

How can I change Status Bar Alpha in iOS 13?

问题 I want to change the Status Bar Alpha in iOS 13. let statusBarWindow = UIApplication.shared.value(forKey: "statusBarWindow") as? UIWindow statusBarWindow?.alpha = 0.5 When I try this, the app crashes (Thread 1: signal SIGABRT). 回答1: The status bar is rendered by a system process (out of the app process) on iOS 13 so there is no way for an app to change this. (Source: speaking to UIKit engineers at the WWDC 2019 labs.) You can see this in the Apple Books app, which used to dim the status bar

A large part of my app consists of web views to provide functionality not yet available through native implementations. The web team has no plans to implement a dark theme for the website.

According to Apple's "Implementing Dark Mode on iOS" Session ( https://developer.apple.com/videos/play/wwdc2019/214/ starting at 31:13) it is possible to set overrideUserInterfaceStyle to UIUserInterfaceStyleLight or
