network extension

Hello!


We have problems with include Network Extension.


Network extension is not available.


We got a new template containing the Network Extension entitlements for our team. We created a new provisioning profile in the "Certificates, Identifiers & Profiles" section of the developer web site with NetworkExtension issue. We created app entitlements file and added "com.apple.developer.networking.networkextension" and "UIBackgroundModes" keys to plist. We have worked with NEHotspotHelper two days, then we added devices to certificate and NEHotspotHelper stopped working. The «registerWithOptions» command always return NO.
We try to create a new certificates, new app ID, but nothing helped.


    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:@"Try here", kNEHotspotHelperOptionDisplayName, nil];
   
    dispatch_queue_t queue = dispatch_queue_create("com.myapp.ex", 0);
   
    BOOL isAvailable = [NEHotspotHelper registerWithOptions:options queue:queue handler: ^(NEHotspotHelperCommand * cmd) {    
                    
        NSMutableArray *hotspotList = [NSMutableArray new];
       
        NSString* command = (cmd.commandType == kNEHotspotHelperCommandTypeEvaluate) ? @"CommandTypeEvaluate" : @"CommandTypeFilterScanList";
       
        NSLog(@"\n %@ \n",command);
       
        if(cmd.commandType == kNEHotspotHelperCommandTypeEvaluate || cmd.commandType == kNEHotspotHelperCommandTypeFilterScanList) {
           
            for (NEHotspotNetwork* network  in cmd.networkList) {
               
                NSLog(@"Hotspot is found ssid: %@, bssid: %@\n", network.SSID, network.BSSID);
                                                       [hotspotList addObject:network];               
            }
           
            NEHotspotHelperResponse *response = [cmd createResponse:kNEHotspotHelperResultSuccess];
            [response setNetworkList:hotspotList];
            [response deliver];
        }
    }];

To quote the documentation:

Most Network Extension classes require you to obtain an entitlement from Apple before using them in your code. To request entitlements, visit https://developer.apple.com/contact/network-extension


In order for the entitlement to be recognized, you provisioning profile has to be specially modified to include the entitlement. You, the developer, aren't able to perform the necessary modification.

Just FYI, the mechanism whereby these special entitlements are added is called a template, and Oliffer mentioned that in their post so I expect they actually have been granted these entitlements.

It’s hard to say for sure what’s going wrong here. It could be that Xcode has automatically regenerated your provisioning profiles and that’s broken things (Xcode has no idea how to deal with special entitlements). I recommend you dump the entitlements of your built binary (both the app and the appex) to make sure that they’re correct. The Debugging Entitlement Issues post explains how to work through this.

We have checked the entitlements in our binary by running the following command:

$ codesign -d --entitlements :- G.R.A.P.E2.app

2. Start by looking at the build log for your executable (in Xcode, choose View > Navigators > Show Report Navigator, then select the appropriate build entry). No logs!

We have checked the entitlements in our binary by running the following command:

You’ve only shown the results for the app. You need to repeat this process for the extension as well as the app. To quote the Debugging Entitlement Issues post:

Remember that, if your app has multiple executables, the main app and an extension say, you’ll have to check the entitlements on each one. Specifically, if you’re using the com.apple.developer.networking.networkextension entitlement it must have the same value in both your app and your extension.

Hello,

I can not understand what are you mean "you’ll have to check the entitlements on each one."

How can i check entitlement without of app.

What are you mean "com.apple.developer.networking.networkextension entitlement it must have the same value in both your app and your extension."

"Same value" - what is value?

I'm already read Debugging Entitlement Issues post and i can not understand what I must to do. Please, write an example of the work with entitlement (Not App),

sample commands if it nedeed. Please, do not ask me to read the docs - I'm already read and have not results.


"com.apple.developer.networking.networkextension entitlement it must have the same value in both your app and your extension."

Where to find this extension?

Hello,

We found an error!

Info.plist file there was incorrect data:

<key>UIBackgroundModes</key>
  <array>
  <string>remote-notification</string>              
  </array>

Correct is:

<string>network-authentication</string>
network extension
