Open Radar FB9147567: Degraded LazyVGrid performance inside a NavigationView and a ScrollView

Attachment, to reproduce it create an app and replace ContentView.swift with this

import SwiftUI

struct Detail: View { let items: [(key: String, value: [String])] = [ (key: "1", value: ["2", "3", "4", "5", "6", "7", "8", "9", "10"]), (key: "2", value: ["2", "3", "4", "5", "6", "7", "8", "9", "10"]), (key: "3", value: ["2", "3", "4", "5", "6", "7", "8", "9", "10"]), (key: "4", value: ["2", "3", "4", "5", "6", "7", "8", "9", "10"]), (key: "5", value: ["2", "3", "4", "5", "6", "7", "8", "9", "10"]) ]

var body: some View {
    ScrollView {
        VStack {
            Text("Lorem ipsum")

            VStack {
                ForEach(items, id: \.key) { item in
                    VStack {
                        Text("Lorem ipsum lorem ipsum \(item.key)")

                        LazyVGrid(columns: [.init(.adaptive(minimum: 150))]) {
                            ForEach(item.value, id: \.self) { text in
                                Button(action: {}) {
                                    VStack {
                                            .frame(height: 150)

                                        VStack {
                                            Text("Lorem Ipsum Lorem")

                                            VStack {
                                                if text.isEmpty {
                                                } else {


struct ContentView: View { var body: some View { NavigationView { VStack { NavigationLink("Open Detail", destination: Detail()) } .navigationTitle("LazyVGrid Issue") } } }

Attached logs, Apple still doesn't care

On April 25 I've been able to reproduce in the simulator. One month has passed and the report is still marked as "Investigation complete - Unable to diagnose with current information".

No further info from Apple.

Open Radar 9106394: Support Ogg Opus in webm container format

There is no way to playback opus encodec audio in Safari, without transcoding (demux webm, mux to caf). This is possible in ffmpeg, however that will involve extra backend and server costs (and energy).

Please support opus in the webm container format too.

Open Radar FB9086375: AVPlayer has a lag when resuming while AirPods Pro are connected to Macbook and iPhone

Response from Apple May 8, 2021 at 12:49 AM

Thanks for contacting us. This behaves as expected currently.

More time is needed to resume playback if the AirPods switched over to the iPhone. 100-200ms delay in playing the video + 150-200ms audio device latency + rerouting to MacBook lines up with this.

We will continue to look into improvements in this area

Please close this feedback report, or let us know if this is still an issue for you. Thank you.

Open Radar FB8940785: InstallEnterpriseApplication package install gets cancelled when Setup Assistant is completed too quickly

11.4 Beta 1 20F5046g fixed the problem

It looks like Apple finally fixed this in 11.4 Beta 1 20F5046g:

• (Beta 1) Setup Assistant no longer skips Location Services when account creation is skipped.

From limited testing I can confirm this. I am going to continue testing until 11.4 final release. If the problem doesn't come back I will consider issue resolved.
