We’ve noticed an issue where after running a network extension, if the phone’s language is changed the Locale.preferredLanguages array is not updated and still returns the old array. It only returns the updated array when the app is reinstalled or the phone is restarted. This is unlike the app itself where using the same Locale.preferredLanguages API immediately returns the updated array. We think this issue is also the cause of notifications that are sent by the network extension being in the previous language as long as the app isn’t reinstalled or the phone is restarted, despite our Localizable file having localised strings for the new language.

On iOS 26 beta 5, it is impossible to add a VPN configuration when a passcode is set on the device. Every time, all it does is redirect to the Settings app with no prompt for passcode. The only way around this is to disable passcode on the device so adding a VPN configuration doesn’t have to open the Settings app. This issue happened intermittently in the past with previous iOS 26 betas and even on iOS 18, but the problem has worsened on iOS 26 beta 5 to the point where you have to turn off passcode to add a VPN.

When using the fullScreenCover API in iOS 26, the content of the displayed view overlaps the content of the view that triggered the fullScreenCover. This issue is not present in iOS 18 and earlier versions. Feedback ID: FB19165084

Sometimes when adding a VPN configuration, it just redirects to the Settings app and doesn’t continue with the rest of the configuration process like prompting for passcode. But it proceeds as normal after the 2nd or 3rd try. This issue is occurring on iOS 18.5 build 22F5068a but it has been a problem over several versions now. Feedback ID: FB17458055

We have an iOS app which includes a packet tunnel provider network extension. We have noticed on rare occasions that the VPN fails to start when we try to start the VPN from the app after installing it. However, rebooting the device or reinstalling the app fixes the issue. When creating the sysdiagnose file, we found some strange messages, a snippet is given below: 2024-09-10 13:40:20.291430 +0100 launchd Could not find and/or execute program specified by service: 2: No such file or directory: /private/var/containers/Bundle/Application/2FA92604-C67D-490D-8E8E-00F8D6FBF990/Sample.app/PlugIns/Tunnel.appex/Tunnel error 2024-09-10 13:40:20.291456 +0100 launchd Service could not initialize: access(/private/var/containers/Bundle/Application/2FA92604-C67D-490D-8E8E-00F8D6FBF990/Sample.app/PlugIns/Tunnel.appex/Tunnel, X_OK) failed with errno 2 - No such file or directory, error 0x6f - Invalid or missing Program/ProgramArguments We encountered this before several months ago on iOS 17.4 and reported it when the issue occurred, but this issue continues to be present in the iOS 18 release candidate. Is there any solution for this issue? Feedback ID: FB13714761

We have noticed that even if we have a localized CFBundleDisplayName, the phone would use the CFBundleName in the VPN permission dialog: " Would Like To Add VPN Configurations" The problem is even if we localize the CFBundleName in the InfoPlist.xcstrings, it still uses the base language in the permission prompt regardless of what language the phone is in. Is it possible to localize the name that's shown in the VPN permission dialog?

We are working on an app which includes a packet tunnel provider extension. The packet tunnel provider works by relaying traffic from a device on the same Wi-Fi network to a remote server via the iPhone's cell socket. As such, it is important for the VPN (and the Wi-Fi connection) to remain running while the phone is locked. We have however noticed that when we lock the phone, the VPN stops running a few seconds later and will remain inactive until the phone's screen wakes up. We have set disconnectOnSleep to false but the issue still remains. Is there a way to keep the VPN alive while the phone is locked?

We are trying to diagnose an issue with our VPN network extension but have discovered that the VPN logging profile, available on the Apple Developer website is not valid: We have tried installing it on multiple phones, including the latest version of iOS 17 with no success so far. We would appreciate if the profile could be updated as soon as possible.
