Reply to SwiftUI Animations inside NavigationView
I have a similar issue with lists in navigationViews. seems any animation causes rendering issues. I experienced it on WatchOS where the app becomes unresponsive when scrolling back to top, right when the navigation bar size is changed. struct TestView: View {     private let items: [String] = Array(0...20).map { String($0) }     var body: some View {         NavigationView {             List {                 Section(header: Text("header")) {                     ForEach(items, id: \.self) { item in                         Text(item)                     }                 }             }             .navigationTitle("Title")         } //        .animation(.easeInOut) // <- this causes rendering problems //        .transition(.slide)     } }

Reply to MPNowPlayingInfoCenter not responding - app freezes
the only workaround I've found was not to read nowPlayingInfo, but only write to it. keeping it's state locally stored

Reply to iOS Team Provisioning Profile: com.xyz.passkit" doesn't include the com.apple.developer.payment-pass-provisioning entitlement.
you need to update the matching provisioning profile at developer.apple.com, too. or try activate 'automatically manage signing' in Xcode project.

Reply to SwiftUI detect system volume change
you need to activate the audio session before it sends updates on Volume changes to your app. AVAudioSession.sharedInstance().setActive(true)

Reply to SwiftUI, List items reordering issue (iOS 16)
has anyone found a workaround for this issue? it's really a blocker. Plus, in iOS16 the move behaviour looks more like a drag now since it is possible to drag a row not only vertically but also horizontally... which looks weird

Reply to Editable Sections in SwiftUI List
no, the edit functions on List are only applied to "rows" not Sections. Plus you can't move between sections

Reply to @StateObject docs correct?
yes, it's confusing, but actually both init.s are the same because { DataModel(name: name) }() invokes the closure immediately, so I'm pretty sure it is the same as DataModel(name: name).

Reply to CoreMediaErrorDomain -12888: Bandwidth down-stepping when using 2sec segment duration
thank you, and the bandwidth down-stepping is the consequence of it? is that the AVPlayer's reaction or could it be a separate issue?
