Hi,after several user reports started with iOS 13, I found the root cause of an issue with my VPN app.Context:- My networking code runs in a custom DispatchQueue with QoS .utility, as per a suggestion by eskimo in another thread.- The NEVPNProtocol.disconnectOnSleep flag is set to false.- I do not override the sleep/wake handlers in NEPackeTunnelProvider.Until iOS 12, the VPN would keep working across the sleep/wake cycles, with the socket handlers surviving the sleep state. This doesn't seem to be the case in iOS 13, so I dug further.By overriding sleep() and wake() in the provider, for logging purposes, I noticed that after a "longer" sleep, DispatchQueue.async() blocks hang up. They literally stop running, to then revive immediately after waking up the device. The effect is that the VPN doesn't disconnect on the sleep event, but triggers a ping timeout as soon as the device is turned on again. Due to inactivity.I can't find a way to restore former "Keep alive on sleep" behavior, because even if the VPN is not actively disconnected on sleep, it still stops working. I mean, does Apple want us to kill the VPN on sleep? Is it an option or a requirement? It's not 100% clear to me from the documentation:https://developer.apple.com/documentation/networkextension/neprovider/1406731-sleep> NEProvider subclasses should override this method if the provider needs to perform any tasks before the device sleeps, such as disconnecting a tunnel connection.Had this been a requirement, it would IMHO be in contradiction with the existence of "disconnectOnSleep". At this point I even wonder if former behavior (iOS 12) was the side-effect of a bug (= queue surviving sleep), eventually fixed in iOS 13.I'd like to know more about this, before looking for a fix in an app that TBH had performed very well until iOS 13.Thanks,Davide

I currently use this hack to determine a TestFlight build on iOS: https://stackoverflow.com/a/32238344/784615 Now that TestFlight also supports macOS, I wonder two things: Is there a standard API to detect a TestFlight build? In general, a TestFlight framework would be HIGHLY desirable If not, anyone knows a hack like the above that would work for macOS? I ask because the in-app receipt is called "receipt" even for TestFlight builds on macOS. Thanks in advance

I encountered a strange behavior that reminded me of when .sheet() modifiers didn't inherit environment objects. Unless I'm missing something very obvious, it seems to me that TableColumn may expose the same issue. At least on macOS, because the very same code does not crash on iOS. I'm posting this here before reporting a SwiftUI bug. Below is a gist for a playground: https://gist.github.com/keeshux/4a963cdebb1b577b87b08660ce9d3364 I also observe inconsistent behavior when building with Xcode 16.1 or 15.4, specifically: https://github.com/passepartoutvpn/passepartout/issues/872#issuecomment-2477687967 The workaround I resorted to is re-propagating the environment from the parent: https://github.com/passepartoutvpn/passepartout/pull/873/files#diff-c662c4607f2adfd0d4e2c2a225e0351ba9c21dbdd5fc68f23bc1ce28a20bce4dR45
