We have an app that registers and runs a NetworkExtension (specifically NEPacketTunnelProvider) on both iOS and macOS. This works fine (although not in the iOS simulator, of course, known limitation). However, when the network extension is running, the App Store on macOS/iOS, and TestFlight on iOS, fail to update the app. It looks like they're waiting for the NetworkExtension to terminate, but not actually asking the VPN to disconnect.
We don't want our users to have to think about killing our VPN (which should stay connected whenever possible), but we don't want them to have to think about updates either - they should happen automatically.
Are we missing something? Is there an event we should be listening on to detect that the store is trying to install an app update? Conditions when we should arrange for the VPN to terminate, safe in the knowledge that it will be restarted again after being updated?
Apple had bugs regarding this issue. It was supposed to be ok since iOS 11 (and macOS 10.13 or 10.14), but then users reported that the problem still exists. Several bugs regarding this are still probably open at Apple's bugs reports, but we can't check their status.
You can ask again at their forum, and open another bug regarding this issue.
Probably there's nothing else you can do.
Those are only some of the reports related to this issue:

Okay, I have asked Reddit 3x and Apple once and no one could answer this so I am coming to you guys. Please be the ones to answer this validly. Okay, details. Yubo remembers my phone after reinstall and I do not know how. I have tried the following:
Changed my IP Address using a VPN
Change my IDFA through reset identifier which I now know is pointless as since I had “limit ad tracking” on the output would have been an output value of numerous 0’s (though this some how got me unbanned from the “Instagram” app, idk how tho)
Changed my IDFV by...well reinstalling the app (Yubo is there only app so don’t ask about other apps from the vendor)
Change my iPhones name multiple times
Prevented the app from being backed up on Icloud then reinstalling
I also logged out of the Icloud prior to using the app for the first time after reinstall
And that’s about it. I am aware the app may recognize: my phone, ios version and hardware. However, none of that is exclusive to my phone. I have read people having the exact same model and phone so i doubt Yubo is remembering me through that. I have never met an app so smart before, but I know some of you have probably been screaming this entire time one thing I have missed so please tell me what i missed and a way to change it without resetting my phone.
My device: Iphone6s and IOS 11
There are previous topics about waking up an application from the background with BLE advertisement (e.g. How to wake up iOS app with bluetooth signal (BLE), Android / iOS - BLE - wake up a terminated application when a BLE device connects).
However my question is not about that since we had this feature working fine up to iOS 9.2 included.
Coming iOS 9.3 the feature doesn't work as it used to work before, it seems that the terminated by user swiping off the application is not woken up. Nothing changed on the BLE advertisement originator.
After a recheck of various parameters and reading of Apple documentation, nothing springs to our minds. Neither Apple documentation mention any change, unless we missed something.
Have other people notice this issue? Are you aware of a solution?
We wrote to Apple and we are pending on an answer but maybe somebody here has the correct tip.
Many thanks in advance for the attention.
UPDATE: After more testing, it seems that only when the user swipes the application out the wake up doesn't work like it used to in iOS 9.2
Initial testing were more manual and gave us the impression that there was an underlying issue. However not sure why this change took place without any notification from Apple. - Above text was amended based on the update -
UPDATE 2: This issue is not present anymore in iOS 10.
It turns out after a reply from Apple that this is a (new) intended behaviour.
didEnterRegion/didExitRegion events stopped working from the background after update to 9.3
I have an app that has been working almost perfectly for the last 6 months, and after the update these events are no longer getting called. I started this app over last year when I heard about iOS9 coming out, and when I couldn't get the old one working, I started a new one using Swift instead.
After some time and a LOT of driving in and out of my Region, I got the app to work more reliably than it ever had before. I have several devices using the app, and when all of them updated to iOS9.3/9.3.1, the app stopped calling didEnterRegion/didExitRegion events completely.
I have a ticket open with Apple, but I am getting a lot of push back about the service, and that 9.3 didn't change background location at all.
My devices use AT&T of Verizon, we have tried wi-fi assist on and off, I even wiped a system, formatted the HD, installed El Capitan, and XCode 7.3, and it's hasn't helped.
I also found an issue with the Devices Tool, and when you download the Container, and open package, the Documents folder is empty. I'm not getting a warm fuzzy feeling for Apple right now, and I am sure someone is feeling my MEGA MIND WEDGIE at this moment.
Help....
I'm trying to log users individual app usage on iOS9.
I'd rather prefer that it wouldn't use jailbreak limited solutions, self explanatory. Doing the variation of this app on a jailbroken phone shouldn't be hard.
This will certainly not be released on the App Store as Apple wouldn't allow it.
I'm looking for any private API that can do this, any hidden iOS API's that can be used to do this. ANYTHING.
What I've already looked through:
how to determine which apps are background and which app is foreground on iOS by application id
How to know about app launched and details jailbreak iOS 7
Is there a private API to be able to detect what is current foreground app on iOS?
How to monitoring App running in the foreground in iOS8？use the PrivateFrameworks SpringBoardServices
which proved to be relatively helpful - we now can assume that there is some sort of additional access requirement, probably an entitlement, but we don't really know how it should look like
Can you find individual app usage duration using SpringBoard services framework or other private framework?
Find out active application or if on Springboard
Programmatically detect which iOS application is visible to user
However all of these proved to be unhelpful because Apple fixed this security flaw with iOS8 and the method to copy/access the currently front most app bundle identifier no longer works.
Question is: Is there someone who knows a workaround using different tools/exploits that do not require jailbreak?
Ideas:
inspecting the processes running on the device and devising an algorithm that would be able to recognize spikes that mean an app has been launched, which potentially could work, but it probably would be a major pain in the ass. Questions mentioning this solution:
Detect which app is currently running on iOS using sysctl,
Return a list of running background apps/processes in iOS
How to get Names of Background Running Apps
Find Background running apps in iphone
inspecting the phones traffic somehow?
not sure if there is some kernel stuff that I could do
Here is my Reddit version of this question if anyone wants to check it out. Also if it's of any value, here are the runtime headers for iOS9 and list of Apple's private API's.
Unfortunately, I was looking for a similar solution and have come to the conclusion that, at least at this point in time, there are no known methods that will allow you to determine app usage on iOS. Even the MDM providers such as Good, Airwatch, MobileIron, etc. don't seem to be able to do this. If anyone is able to come up with a solution, I'd love to see it.
For now, however, I think we would have seen a solution if someone had one that worked on the latest iOS.
sysctl is still open but they block certain combinations of selectors. I did this on iOS 7 and gave Apple Product Security the code. They won't patch iOS 7 but rely on App Review. iPhone 4 is wide open.
I'm setting up an MDM installation to distribute apps to supervised devices and seem to regularly get the managed application into a weird state where it's "scheduled for management" but doesn't actually install to the device. It's unclear to me how it gets into that state or how to get it out of that state.
I tried to use the RemoveApplication command, but since it never actually installed, this failed to remove it. I was able to get it out of this state by turning the device off and letting it forget it's volatile memory and then turning it back on, but this is an unacceptable solution for the use case I'm trying to achieve. It also doesn't seem to always fix the issue.
I attempted to use a support ticket with Apple to resolve this, but they basically told me that the problem we're experiencing should be submitted as a bug report, so we submitted that to them.
Basically, I'm just wondering if anyone else has experienced this issue and if you have, do you know of any workarounds to get it out of this state?
Thanks!
I submitted my app update for review a week or so ago and it worked fine for me when i submitted it (on multiple devices and emulator). Apple reviewed it and approved it and now whenever users download it, the app just hangs at the splash screen forever. On iOS 6 beta it immediately crashes. I believe it must be something wrong with the package that Apple put on the store for download, but i honestly have no idea. Anybody had this happen before or anyone have any ideas on how you can debug a problem like this?
This is maybe the 30th or so time i've submitted something to Apple and this is the first time anything like this has ever happened. I have used a technical support incident to contact apple and no response so far from that. I also used the contact us page on the itunesconnect portal to ask about it and no response from that either. Both of those were done on Friday. As a secondary question, does anyone know how long it takes to hear back from Apple when you submit questions in either of those ways?
I faced the same issue. It was a DNS issue. It drove me mad for months, since I could not reproduce the issue. However one poorly configured WiFi helped me reproduce the issue by chance.
iOS tries to perform DNS lookup at the beginning of the app lifecyle. This is even before a single line of code is executed. If the DNS lookup is performed on the main thread synchronously, it blocks the UI. This issue arises only in cases where its trying to resolve the DNS for about 30s while blocking the UI. Hence the iOS watchdog kills the app due to a timeout. Apple also has a doc for this- https://developer.apple.com/library/prerelease/ios/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/CommonPitfalls/CommonPitfalls.html
You can search for DNS lookup in your code and check its execution. In my case it was a 3rd party C-library that was causing an issue.
I know its been really long since this question was asked, hope it helps someone.
