QNEAppProxy shows how to implement a basic Network Extension app proxy tunnel provider.
Xcode 9.0
The sample was built using Xcode 9.0 on OS X 10.12.6 with the iOS 11.0 SDK. To build the sample open the project, make sure the App-iOS scheme is selected, and choose Product > Build.
+++ discussion of provisioning
iOS 10.0
The core code should work on iOS 9 but the bulk of the testing was done on iOS 10 and later.
The sample contains the following items:
-
README.md— This file. -
LICENSE.txt— The standard sample code license. -
QNEAppProxy.xcodeproj— An Xcode project for the sample. -

The TestApp-iOS target exists because an app proxy provider can’t catch the network connections issued by its containing app.
When testing SafariDomains make sure to remove NETestAppMapping from the app’s Info.plist because that test setting interferes with the normal operation of SafariDomains.
The app requests to post user notification on launch because I used it to confirm that Network Extension providers can post such notifications via the User Notifications framework.
If you find any problems with this sample, or you’d like to suggest improvements, please file a bug against it.
1.0d1 (6 Jan 2017) was distributed to a small number of developers on a one-to-one basic.
1.0d2 (2 Feb 2017) was distributed to a small number of developers on a one-to-one basic. Add a test app target that is enrolled in the per-app VPN. Changed the network test infrastructure such that it can run inside the app proxy provider.
1.0d3 (2 Oct 2017) was distributed to a small number of developers on a one-to-one basis. Switched to using automatic code signing. Updated to Xcode 9. Moved all the test code to the test app. Added some caveats to the read me. Added a macOS build. Got on OnDemandMatchAppEnabled working on macOS.
1.0d4 (4 Oct 2017) was distributed to a small number of developers on a one-to-one basis. It fixed a problem with 1.0d3 where it was missing some expected features due to a tagging error.
