While generating the Xcode build with Address Sanitizer enabled, I am unable to launch the PacketTunnelProvider provider.
The process is getting killed by the Operating System with the below exception
"Thread 1: EXC_RESOURCE RESOURCE_TYPE_MEMORY (limit=50 MB, unused=0x0)"
I understood that since Packettunnel Provider extension has only a memory limit of 50 MB, Operating System is killing the process. Is there any other way, we can overcome this limitation and perform Address Sanitizer testing ?

This is where we write to user defaults
`18 Foundation 0x00000001844fb754 -[NSUserDefaults(NSUserDefaults) setObject:forKey:] + 80

Due to loopback VPN implemented using PacketTunnelProvider, we observed issues regarding failing to update WatchOS.
Is there any workaround for this ? Does WatchOS update is supported using proxy or VPN using Packet tunnel Provider ?

Can anyone help me with how to interpret this crash log? I have attached the crash stack, it is reported only a particular user device and was reported multiple times.
I have masked few keywords in the stack trace for confidentiality purpose

Hello
I would like to know if Apple might reject an app during review if there is a navigation from App to settings programatically, as we have seen few stack-overflow links for the same.
The below code will be executed on button press which takes the user to settings.
if let appSettings = URL(string: UIApplication.openSettingsURLString) {
UIApplication.shared.open(appSettings, options: [:], completionHandler: nil)
Please let me know if any there is any chance of rejection with the above code.

While trying to add a new VPN configuration , the ios Network Extension fails for a particular device with my App with the following error
default 23:34: 34.140388-0400 Adding 918D08B1-2814-47C0-AAA9-0A0A8C92049C to the loaded configurations
error 23:34:41.386023-0400 nehelper : Cannot save configuration , the total size of the NetworkExtension configuration is to large (2643248 bytes)
default 23:34:41.510241-0400 kernel memorystatus: set assertion priority(10) error
The same behaviour is seen with other VPN Providers like Tunnel Bear.
Question: As this issue is seen only on a particular device. Has anyone seen this issue/able to mitigate , and also shed more details why this issue happens.
