I'm researching to develop a VPN application on tvOS 17.0, but even if I set the dev target version to 17.0, it still prompts me that the API is not available.

'NEPacketTunnelProvider' is only available in tvOS 17.

I have 2 xcodes installed on my computer, I tried switching to sudo xcode-select -s /Applications/Xcode-beta.app/Contents/Developer, but it still doesn't work. Is there anything else I need to set?

@eskimo We managed to solve this issue. Looks like a bug on xcode 15+

The simplest solution is to change the productType of your Network Extension target from com.apple.product-type.tv-app-extension to com.apple.product-type.app-extension.

Somehow it's working fine again. however the extension keeps not working:

ASI found [CoreFoundation] (sensitive) '*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** NSExtensionPrincipalClass PacketTunnel.PacketTunnelProvider must implement at least one public protocol''

class PacketTunnelProvider: NEPacketTunnelProvider {
    
    override func startTunnel(options: [String : NSObject]? = nil, completionHandler: @escaping (Error?) -> Void) {
        completionHandler(nil)
    }
    
    override func stopTunnel(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) {
        completionHandler()
    }
}

See this thread. It doesn’t have any real answers yet, but if I uncover anything new I’ll update that thread rather than this one.
