ok, did found the needed solution: https://developer.apple.com/documentation/networkextension/nevpnmanager/1406382-enabled?language=objc https://developer.apple.com/forums/thread/679975

Can the DNS Proxy network extension be launched by the system as a result of (dns proxy and packet tunnel provider network extensions are embedded in the native app): System launches packet tunnel provider network extension (as result of user switched on the VPN button in settings). Successful connection (packet tunnel is opened and connected). Can that be done? When a user is using the native app, the app uses the APIs and triggers / launches the packet tunnel provider. Then on success opening / connection the app launches the DNS Proxy. We would like to have the same abilities when the user triggers the packet tunnel provider from the settings app. Can that be done?

iOS, macOS M1 The desired resolute is: when the tunnel packet provider is launched by the settings app, the dns proxy will be triggered and launch as a resort of successful opening of the tunnel packet provider. Thanks for any help on that!

Thanks for the quick answer! However what is the reason that the DNSProxyProvider is not running on the Mac M1 (when execute / run using the Xcode)? It is performing ok on any iOS device.

Have a similar issue on Mac M1 (Monterey - 12.2), on iOS that seams to work fine, but on the macOS M1 that appears as not running with a yellow dot. Is to support the macOS on M1 I need to use system extension? my tunnel provider implementation is running the same on any iOS device iPhone or the M1.. can any one explain..?
