How to check if my network connected to mobile hotspot as Wifi

Take a look at NWPathMonitor for detect path changes between cellular and Wi-Fi.

You will want to take a look at the pathUpdateHandler to detect changes between cellular and Wi-Fi.

I appreciate your reply Meaton.

Yes, NWPathMonitor delegates whenver the network status changes and it works in iOS.

I have created a Cocoa(macOS) application and using NWPathMonitor, is it possible to get to know when MacBook Air WiFi connected to my cellular network via hotspot enabled.

My Cocoa app should identify whenever the network connected via Wi-Fi or via Celluar (hotspot enabled) network.

let monitor = NWPathMonitor(requiredInterfaceType: .wifi)
        let queue = DispatchQueue.global(qos: .background)
        monitor.start(queue: queue)
        monitor.pathUpdateHandler = { path in
            if path.status == .satisfied {
                print("Connected")
            }
        }

if i change the requiredInterfaceType as ".cellular". am not getting the path.status as .satisfied. It always says interface type as .wifi even if i connected via cellular hotspot.

If are wanting to know whether the Wi-Fi connection is sourced from an access point or a hotspot enabled device, then NWPathMonitor will not provide this information. NWPathMonitor see's correctly sees both connections as Wi-Fi connections.

let nwPathMonitor = NWPathMonitor()
nwPathMonitor.pathUpdateHandler = { path in
   
    if path.usesInterfaceType(.wifi) {
        // Correctly goes to Wi-Fi via Access Point or Phone enabled hotspot
        os_log("Path is Wi-Fi")
    } else if path.usesInterfaceType(.cellular) {
        os_log("Path is Cellular")
    } else if path.usesInterfaceType(.wiredEthernet) {
        os_log("Path is Wired Ethernet")
    } else if path.usesInterfaceType(.loopback) {
        os_log("Path is Loopback")
    } else if path.usesInterfaceType(.other) {
        os_log("Path is other")
    }
}
nwPathMonitor.start(queue: .main)

What are you looking to do with this information?

I have one usecase to implement in such a way that i can intimate/alert the user in case of network changes (Wifi/Cellular). Let me know if any other solutions are there to achieve this.

Thanks for your suggestions. You saved my time.

For macOS detecting changes between Wired Ethernet, Wi-Fi, and Loopback is what you are looking for with NWPathMonitor.

There is no API for detecting whether the Wi-Fi connection is sourced from a Hotspot connection or from a access point.

Thanks for your time.

but I just want to know type of network mobile device is connected at given time. like want to know whether it's wifi or LTE or wired Ethernet.

Code Block swift
let nwPathMonitor = NWPathMonitor()
nwPathMonitor.pathUpdateHandler = { path in
   
    if path.usesInterfaceType(.wifi) {
        os_log("Path is Wi-Fi")
    } else if path.usesInterfaceType(.cellular) {
        os_log("Path is Cellular")
    } else if path.usesInterfaceType(.wiredEthernet) {
        os_log("Path is Wired Ethernet")
    } else if path.usesInterfaceType(.loopback) {
        os_log("Path is Loopback")
    } else if path.usesInterfaceType(.other) {
        os_log("Path is other")
    }
}
nwPathMonitor.start(queue: .main)

I need to catch the event of connecting and disconnecting a iPhone to an external camera. The connection is via wifi. Reachability library is not up to the task. I also tried the code above, but it doesn't work either.

The problem is that when the iPhone is connected via mobile data (or air mode is turned on) and simultaneously connect to the camera via wifi, none of the methods sends me any event. Tell me how to solve this problem

Code Block swift
reachability = try? Reachability(hostname: currentCamera.ipAddress)
