I'm trying to update to the macOS Big Sur beta (day 1!) but the installation keeps failing with a timeout. I get a popup that says: An error occurred installing macOS. The request timed out. If I go into /var/log/install.log, there's some detail here, showing that bridgeOS timed out. What's the fix for this? Here are the last lines of the install.log file: 2020-06-22 23:46:18-05 Andrews-MacBook-Pro-4 osinstallersetupd[384]: Started downloading package com.apple.pkg.BridgeOSBrain (http://swcdn.apple.com/content/downloads/04/28/001-18400-A_9PR1LXEKFC/czmgv59ffn8j0u96xf2tu7tiu2ykcp3izt/BridgeOSBrain.pkg) 2020-06-22 23:46:18-05 Andrews-MacBook-Pro-4 osinstallersetupd[384]: Retrieved package com.apple.pkg.BridgeOSBrain (http://swcdn.apple.com/content/downloads/04/28/001-18400-A_9PR1LXEKFC/czmgv59ffn8j0u96xf2tu7tiu2ykcp3izt/BridgeOSBrain.pkg) 2020-06-22 23:46:18-05 Andrews-MacBook-Pro-4 osinstallersetupd[384]: Starting bridgeOS update prepare 2020-06-22 23:56:18-05 Andrews-MacBook-Pro-4 osinstallersetupd[384]: bridgeOS update prepare timed out! 2020-06-22 23:56:18-05 Andrews-MacBook-Pro-4 osinstallersetupd[384]: Operation queue failed with error: Error Domain=com.apple.OSInstallerSetup.error Code=601 "An error occurred installing macOS."

I was just watching the Enhance voice communication with Push To Talk WWDC22 session video and was wondering (a few questions) -- (1) (when) will you be making the demo app available that was shown at the beginning of the video? (2) There was some detail given regarding the new APNs push type ("pushtotalk"), but it was unclear to me if that's something I need to handle manually, or if those will be sent automatically when I do channelManager.requestBeginTransmitting? (3) How does the audio data itself get routed around? Is that handled by the system between the requestBeginTransmitting and stopTransmitting calls? Or somehow part of the APNs payload? Or something we must handle? Thank you! thanks!!

Okay, so I created a new Xcode project using SwiftData, and ticked the box for iCloud integration. I added a container on the web dashboard. Then I added “ = Date()” to the definition of Item.timestamp so that it has a default value. I added the container to my Xcode project.. Then I added this “let config” and “let container” and changed the “.modelContainer” like this: This will successfully add stuff to core data, which also appears in iCloud dashboard. BUT, if I delete the app and re-launch, I don’t see the existing iCloud data until the SECOND launch, even though the Xcode runtime log shows it fetched it. Do I need to do some magic to get it to refresh? Is the CloudKit subscription managed by SwiftData or do I need to do something for that? thanks!

I'm seeing an error trying to test out async let. It seems like this should work, based on the async/let and structured concurrency session videos. Here's the code: func doIt() async -> String {     let t = TimeInterval.random(in: 0.25 ... 2.0)     Thread.sleep(forTimeInterval: t)     return String("\(Double.random(in: 0...1000))") } async {     async let a = doIt()     async let b = doIt()     async let c = doIt()     async let d = doIt()     let results = await [a, b, c, d]     for result in results {         print("  \(result)")     } } But, I get this error for every "async let" statement: error: AsyncLetSwift55WWDC21.playground:12:15: error: expression is 'async' but is not marked with 'await' async let a = doIt() ^ await Am I missing something key, or is this a bug? I'm running this in the Xcode 13.0 beta, in a Playground. Thanks!!
