User Profile

Hello, I noticed an issue with my VPN configuration created with NETunnelProviderManager. When the user has multiple apps that use VPN configuration and are active, I cannot activate my network extension. I am getting this error: NEVPNError.Code.configurationDisabled For ObjC it's NEVPNErrorConfigurationDisabled An error code indicating the VPN configuration associated with the VPN manager isn’t enabled. So if this happens, I need to open Settings - VPN and select my app's profile. How to do this programatically? Other apps are able to re-enable their VPN profile, if another one was selected.

Hello, I am working on a NetworkExtension that uses NEPacketTunnelProvider. Is there any option to somehow see all traffic that gets send to my extension? Some apps have issues working over my tunnel, so I want to check the connections and see what is happening.

Hello, I am working on a small app to easily create time relative reminders. Meaning I can quickly create reminder that will remind me about something after 45 minutes from now.. I want to add configurable shortcuts, so users can use this app via Siri and the Shortcuts app. I have created the Intents.intentdefinition file and it's (so far one) shortcut correctly displays in the Shortcuts app with the parametrs. But I am unsure how should I now handle it? Some tutorials and docs mention the delegate methods in SceneDelegate while others point to Intents Extension which is supposed to handle the shortcut? swift override func restoreUserActivityState(_ activity: NSUserActivity) { } This shortcut what I want does not need more user interaction than just providing the two input parameters. So the simplest way to handle that would be nice. Ideally if that work could happen in background without opening my app? Because after the reminder is added, there is nothing to do in my app. Is that possible?

Hello, I am working on a NEPacketTunnelProvider and I am not exactly sure if I correctly understand the NEPacketTunnelNetworkSettings. For example the ipv4Settings according to docs: This property contains the IPv4 routes specifying what IPv4 traffic to route to the tunnel, as well as the IPv4 address and netmask to assign to the TUN interface. So this seems like unless I set all the possible routes here, the tunnel should not work for all the traffic? Currently I have this: swift let ipv4Settings: NEIPv4Settings = NEIPv4Settings( addresses: ["192.169.89.1"], subnetMasks: ["255.255.255.255"] ) Which seems to work pretty well, both for WiFi and cellular. In the past I tried various other addresses, even manually including all the IPV4 routes but I never noticed any effect regarding the tunnel. Then there is the includedRoutes property. The routes that specify what IPv4 network traffic will be routed to the TUN interface. So this is basically another way to set the address like in the constructor for NEIPv4Settings? This seems to work best when I don't set anything. I tried setting all the routes but that did not change things a bit. The only difference is when I set includedRoutes to NEIPv4Route.default(). Then some apps stop working when the tunnel is active. This is strange, because even setting all the available routes + default one doesn't fix this "issue". What is the relation between these properties? It is best to not set includedRoutes if the tunnel works fine? And lastly. What about dnsSettings? This looks like another optional property. Does it make sense to manually specify DNS to point maybe to 1.1.1.1?

Hello, I initially started the discussion over at Swift Forums - https://forums.swift.org/t/issue-with-connect-proxy-some-connections-dont-work-probably-sockets/45575 because I am using SwiftNIO but it appears that it makes more sense here. I have an app with NetworkExtension of the packet tunnel provider type. So I am using the NEPacketTunnelProvider. As part of the extension, I have SwiftNIO server with connect proxy which is used to route the traffic. This works great in almost all cases, but apps like Signal or WhatsApp don't work. They don't display any kind of "no connection" indicator but the messages aren't send or received. Over at Swift Forums I got an answer from Quinn “The Eskimo!” that I think points to the actual problem: My experience is that a lot of these ‘chat’ apps explicitly bind their connections to the WWAN interface, which means they don’t use the default route and thus aren’t seen by the packet tunnel provider. My packet tunnel provider is configured to use the default routes for IP4 and IP6. So my concern is how to configure it, that it works also for the chat apps? There are couple of apps from the App Store that I tried which use this same approach and while they are active, Signal works fine. Yes, I know this solution is not ideal and not the main intended usecase for packet tunnel, but it is the only option available on iOS.. Thanks for help! Happy to clarify further.

Hello, so I started using Compositional layout for cases where previously I would use either a Table View or Collection View with the Flow layout. While Compositional works great for complex layout, I have a bit of an issue building simple screens. For example one header cell and then three tappable cells below it. let itemSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1), heightDimension: height) let layoutItem = NSCollectionLayoutItem(layoutSize: itemSize) let layoutGroup = NSCollectionLayoutGroup.vertical(layoutSize: itemSize, subitems: [layoutItem]) I am using this setup to setup the only group that gets passed to the NSCollectionLayoutSection and it works great, but I dont know what is the best way to specify height? I am using .estimated(200) for now, but this in the end (correctly) results in header that has height like 300 and then those buttons with 45 each. I just feel like I am not using the Compositional layout sizing properly. Thanks for help.

Hello! I am playing around with the PHPickerViewController and so far I was able to get the selected images by loading them into UIImage instances but I don't know how to get the selected video. Below is the relevant implementation of the method: func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]): let provider = result.itemProvider guard provider.hasItemConformingToTypeIdentifier(AVFileType.mov.rawValue) else { return } 						provider.loadItem(forTypeIdentifier: AVFileType.mov.rawValue, options: nil) { (fileURL, error) in 								if let error = error { 										print(error) 										return 								} 								guard let videoURL = fileURL as? URL else { return } 								DispatchQueue.main.async { 										let fm = FileManager.default 										let destination = fm.temporaryDirectory.appendingPathComponent("video123.mov") 										try! fm.copyItem(at: videoURL, to: destination) 										let playerVC = AVPlayerViewController() 										playerVC.player = AVPlayer(url: destination) 										self.present(playerVC, animated: true, completion: nil) 								} 						} I get crash trying to copy the item. It says the source file does not exists but the path looks real to me. "The file “3C2BCCBC-4474-491B-90C2-93DF848AADF5.mov” couldn’t be opened because there is no such file." I tried it without copying first and just passing the URL to AVPlayer but nothing would play. I am testing this on a simulator. Thanks for help!
