I have a Package.swift // swift-tools-version: 5.9 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "SharedUI", defaultLocalization: "en_US", platforms: [.iOS(.v16)], products: [ .library( name: "SharedUI", targets: [ "AppTheme", ] ), ], dependencies: [ .package(url: "https://github.com/apple/swift-markdown.git", "0.2.0"..<"0.3.0"), ], targets: [ .target( name: "AppTheme", dependencies: [ .product(name: "Markdown", package: "swift-markdown"), ], path: "AppTheme" ), ] ) Run swift package show-dependencies shows error yuantong-macbookpro2:Downloads yuantong$ swift package show-dependencies Fetching https://github.com/apple/swift-markdown.git from cache Fetched https://github.com/apple/swift-markdown.git (0.67s) error: Couldn’t get the list of tags: fatal: cannot use bare repository '/Users/yuantong/Downloads/.build/repositories/swift-markdown-b692ce3c' (safe.bareRepository is 'explicit') which I think used to work before Xcode 15.

When working with this example code from Apple Implementing Interactions Between Users in Close Proximity, the example comes by default in Swift5, however when I switch to Swift6, the example would crash. I also observed the same crash in my personal project (this is why I tried the example code), currently blocking me. To repro: Download sample code from link Go to build settings and use Swift 6 Go to AppDelegate and change @UIApplicationMain to @main as this is required for Swift 6. Run the sample app on 2 iOS devices.

I have some trouble to use this API https://developer.apple.com/documentation/xctest/xcuisystem/4108234-open in UI testing. Calling this API that opens my app but a system dialog Open in "MyApp" will show. XCUIDevice.shared.system.open(url) is a sync API, so I can't use my test to tap on the "Open" button on the dialog. This basically makes the API unusable, are there some way to bypass this system dialog?

I'm using RealityView in my iOS game mxied with SwiftUI. For the following 2 example usages, the simulator will only render the first RealityView, and the second one is either super laggy or show a black model. Running on the real device is all good, just simualtor has this issue. Have a TabView and each tab has a RealityView. Have a root view and detail view connected via a push navigation, both root and detail have a RealityView. In the Simulator, the second RealityView is going to be very choppy and basically unusable, but on a real iPhone everything looks great. Is this a known simulator issue or I did something bad?
