We're also seeing this issue with Xcode 16.3. The app crashes on startup on simulators running < iOS 18.4. In our case we see the issue with WKPDFConfiguration and with WKWebView.find. When we remove those from our code it runs fine. Here's some minimal code that causes the crash (on < iOS 18.4): import SwiftUI import WebKit // Add one of these in ContentView.Swift struct WebViewRepresentable: UIViewRepresentable { func makeUIView(context: Context) -> WKWebView { let webView = WKWebView() let url = URL(string: "https://apple.com")! let request = URLRequest(url: url) webView.load(request) // Causes crash on < iOS 18.4 webView.find("apple") { _ in } return webView } func updateUIView(_ uiView: WKWebView, context: Context) { } } I've also run the following: nm -gU <path-to-simulator-ios-version-runtime-frameworks>/WebKit.framework/WebKit> | grep find. The symbols show up in iOS 18.4 but not others. Here an example of a full path to the WebKit framework in case its useful to anyone: /Library/Developer/CoreSimulator/Volumes/iOS_22C150/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 18.2.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/WebKit.framework.

I can't speak to the ShazamKit issue, but as of yesterday (or maybe the day before) the libswiftWebKit.dylib issue seems to have cleared up. After posting here I checked and our TestFlight build from the night before and found that it didn't have the issue, it would run on Mac (Designed for iPad). Our TestFlight upload from last night worked as well. It seems like something in App Store Connect has been fixed.

Same issue here (libswiftWebKit.dylib). This started within the last two weeks out of the blue. It's currently holding up our next release. Report as FB16650686

In my case my List has a mix of DiscloseGroup rows and normal rows. My rows each have a checkbox such that if you check a row off it moves the row to the bottom (.i.e re-sorts the list within a withAnimation block). I'm seeing the bad animation when two or more DisclosureGroups are adjacent in the List. If you check the top one, then in the re-order animation it moves the row underneath down to the bottom, instead of the row you tapped, and then updates the row content for each of those rows, the original position and new position, at the end of the animation. If you try this when the DiscloseGroup is expanded it animates moving all the children but not the row itself. If you try this with a normal (non-DisclosureGroup) row, or a DisclosureGroup row that doesn't have a DisclosureGroup right below it, it works fine. I'm on iOS 17 as well.

I'm seeing a fix for this in WebKit (https://bugs.webkit.org/show_bug.cgi?id=232295). Hopefully it gets pull into an iOS update soon.

We're having the same issue. We have a non-opaque web view that renders our content, relying on the view underneath for background color. In our dark mode the scroll indicator can't be seen.

I'm in the same boat. On iOS 15 beta 2 and Xcode beta 2 and the FamilyActivityPicker shows categories on both guardian and child device but the categories don't expand to show any apps. Furthermore, I don't understand how this would work on the guardian device. I would want to see a list of a specific child's apps, but I don't see anyway to specify which child of my 4 kids the FamilyActivityPicker should show apps for.
