Reply to Summary of '27 Changes?
You asked this is the Networking Q&A and I discussed it internally with the team. Unfortunately we don’t have a good answer for you. The folks in the Q&A tend to be specialised in their specific area, so we don’t have anyone who can create a summary like this. But hey, isn’t that what LLMs are for?

Reply to iPad stubbornly sticks to one AP rather than roaming
Apple Developer Forums is primary focused on code-level questions, so we can’t really help you with issues like this. You have a couple of options here: You can seek help from Apple Support. If you think that iOS is behaving incorrectly, you can file a bug about that. For the latter, see Filing a Wi-Fi Bug Report for hints and tips about… well… filing Wi-Fi bugs.

There are limits to how much we can answer questions like this. See tip 3 in Quinn’s Top Ten DevForums Tips. However, if you want to see the shortcut expose specific information then my advice is that you file an enhancement request outlining your requirements. If you do file a bug, please post your bug number, just for the record. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

I’ll be interested to hear what other folks have to say about this. About all I can say definitively [1] is that Apple doesn’t have any tools for it. I’ve seen reports online of folks have great success using GenAI tools to help with this task, but I don’t have any personal experience I can share. However, if you search the ’net for terms like GenUI objective-c to swift you’ll find lots of hits.

Rather, I think it’s better to extract the core concepts from those samples that are relevant to your app, and then adapt those concepts to Swift 6.

Reply to What is the best way to symbolicate crash reports from the new MetricKit framework?
CrashReportExtension and MetricKit perform very different functions, but in terms of symbolication I don’t think there’s any need for you to make a change here. In general, it’s better to symbolicate off device, which means recording a list of Mach-O image UUIDs and load addresses. MetricKit gives you that, so there’s no reason to deal with the complexities of CrashReportExtension. CrashReportExtension makes sense if you want to do something much more custom, for example, if you want to reach into the corpse (ewwww!) and extract state that’s not available in the standard crash report given to you by MetricKit.

Reply to Screen Reader for macOS implemented with Swift Concurrency and Distributed Actors
There aren’t any question marks in your post, so it’s not clear what your actual question is. I suspect you’re looking for feedback on your RunLoopExecutor package. If so, yeah, I’ve been down that path myself a few times and your code looks very like my first version. The biggest issue with it is that it relies on Thread being thread safe, which is not the case (much to my surprise). Hence your need for that nonisolated(unsafe). In my quest to get around that I eventually created something much more complex. Sadly, it’s still requires unsafe stuff, but I bounded that to one thing that I consider to be safe (passing CFRunLoop references between threads) and two things that I consider to be Safe Enough™ (calling CFRunLoopSourceSignal and CFRunLoopWakeUp from another thread). Needless to say I’m not really happy with that result, and that’s one of the reasons I’ve not shared my code more widely.

Reply to I have an iOS app that now cannot connet to websocket servers when building with new SDKs
There are many different potential causes for this, so it’s hard to offer a concrete suggestion as to why this is failing. My advice is that you debug your code to see where things are going wrong. Once you have a rough idea of what’s failing, we may be able to advice more concrete suggestions.

Reply to await?
I think that’s a typo. Certainly, there’s nothing about await? in the Swift Evolution proposal for this much-requested feature, namely SE-0493 Support async calls in defer bodies. Moreover, it’s not the only typo in that code. For example, it uses both fileName and filename. Here’s a code snippet that compiles with Xcode 27 beta: import Foundation class FileHandle { init(_ fileName: String) { fatalError() } func write(_ data: Data) async throws { fatalError() } func close() async { fatalError() } } func exportData(at url: URL, to fileName: String) async throws { let log = FileHandle(fileName) defer { await log.close() } let (data, _) = try await URLSession.shared.data(from: url) try await log.write(data) } Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com
