How to use with NetworkExtension framework

[waqqasjabbar]

Hi
I want to call functions in the NetworkExtension Framework. Any ideas on how to do that would be helpful. Specifically, I want to call loadAllFromPreferencesWithCompletionHandler within NETunnelProviderManager

I am giving it a try (code here) but getting a VM crash. Any help would be appreciated.

Regards

Completion handler aka callbacks are not supported. You will have to write a proxy ObjC class with a function like (pseudo code in Swift)

public class CallbackNETunnelProviderManager: NSObject {
@objc public class func loadAllFromPreferences(completionHandler: MyCompletionHandlerCallback
{
        NETunnelProviderManager. loadAllFromPreferences(completionHandler: { error in
            completionHandler?.didFinish(nil, withError: error)
        })
}

@objc(FileProviderManagerConnectCallback)
public protocol MyCompletionHandlerCallback {
    func didFinish(_: AnyObject?, withError error: Error?)
}
