/// Uses bonjour networking to relialby check if user has granted local network access

        self.netService?.delegate = self
        
        self.browser?.start(queue: .main)
        self.netService?.publish()
    }
    
    
    private func reset() {
        self.browser?.cancel()
        self.browser = nil
        self.netService?.stop()
        self.netService = nil
    }
}

extension LocalNetworkAuthorization : NetServiceDelegate {
    public func netServiceDidPublish(_ sender: NetService) {
        self.reset()
        print("Local network permission has been granted")
        completion?(true)
    }
}

netServiceDidPublish never gets called, could you help me understand why?

@Rytiggy you need to schedule the netService on a run loop (I did it on the main runloop)

netService?.schedule(in: .main, forMode: .common)
