How to detect if the internet connection is over WiFi or Ethernet?

Question

Is there a way to open network settings programmatically? Closest thing I know is opening the main settings page:

let settingsURL = NSURL(string: UIApplicationOp

For iOS 12.0+, tvOS 12.0+, macOS 10.14+ and watchOS 5.0+ apps you can use NWPathMonitor to solve the problem that you described in your question. Add this code to your application(_:didFinishLaunchingWithOptions:) implementation (Swift 5.1.3/Xcode 11.3.1):

let pathMonitor = NWPathMonitor()
pathMonitor.pathUpdateHandler = { path in
    if path.status == .satisfied {
        if path.usesInterfaceType(.wifi) {
            print("wifi")
        } else if path.usesInterfaceType(.cellular) {
            print("cellular")
        } else if path.usesInterfaceType(.wiredEthernet) {
            print("wiredEthernet")
        } else if path.usesInterfaceType(.loopback) {
            print("loopback")
        } else if path.usesInterfaceType(.other) {
            print("other")
        }
    } else {
        print("not connected")
    }
}
pathMonitor.start(queue: .global(qos: .background))

And don't forget to add import Network to the top of the file.
