How to determine the Apple Watch model?

问题

The WKInterfaceDevice.current().model property does not give a model number:

For Apple Watch, the value of this string is Apple Watch.

How can the exact Apple Watch model be determined from iOS?

回答1:

There is no public API to get that exact information.

You can however use the following (I'll let you translate into Swift):

- (NSString*) modelIdentifier {
    size_t size = 0;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char* machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString* model = [NSString stringWithCString: machine encoding: NSUTF8StringEncoding];
    free(machine);
    return model;
}

This returns a string in the format: "Watch1,1". You'll need to provide a lookup table to do ID -> Name translation.

"Watch1,1" -> Apple Watch 38mm
"Watch1,2" -> Apple Watch 42mm
"Watch2,3" -> Apple Watch Series 2 38mm
"Watch2,4" -> Apple Watch Series 2 42mm
"Watch2,6" -> Apple Watch Series 1 38mm
"Watch2,7" -> Apple Watch Series 1 42mm
"Watch3,1" -> Apple Watch Series 3 38mm Cellular
"Watch3,2" -> Apple Watch Series 3 42mm Cellular
"Watch3,3" -> Apple Watch Series 3 38mm
"Watch3,4" -> Apple Watch Series 3 42mm

By the way, this sysctlbyname API also works for iOS.

Cheers.

EDIT: no longer works for watchOS 4+

This is the Swift 4+ version: working fine for me :)

func getWatchModel() -> String {
    var size: size_t = 0
    sysctlbyname("hw.machine", nil, &size, nil, 0)
    var machine = CChar()
    sysctlbyname("hw.machine", &machine, &size, nil, 0)
    let model = String(cString: &machine, encoding: String.Encoding.utf8)
    switch model {
    case "Watch1,1":
        return "Apple Watch 28mm"
    case "Watch1,2":
        return"Apple Watch 42mm"
    case "Watch2,3":
        return "Apple Watch Series 2 38mm"
    case "Watch2,4":
        return "Apple Watch Series 2 42mmm"
    case "Watch2,6":
        return "Apple Watch Series 1 38mm"
    case "Watch2,7":
        return "Apple Watch Series 1 42mm"
    case "Watch3,1":
        return "Apple Watch Series 3 38mm Cellular"
    case "Watch3,2":
        return "Apple Watch Series 3 42mm Cellular"
    case "Watch3,3":
        return "Apple Watch Series 3 38mm"
    case "Watch3,4":
        return "Apple Watch Series 3 42mm"
    default:
        return "unknown"
    }
}

Just slightly updating @Mathieu Vandeginste answer for WatchOS 6 and Apple Watch Series 5.

private func getWatchModel() -> String? {
   var size: size_t = 0
   sysctlbyname("hw.machine", nil, &size, nil, 0)
   var machine = CChar()
   sysctlbyname("hw.machine", &machine, &size, nil, 0)
   return String(cString: &machine, encoding: String.Encoding.utf8)?.trimmingCharacters(in: .whitespacesAndNewlines)
}

This needed one change for WatchOS 5 to trim the raw string from getWatchModel() as it now ends in a tab using: ?.trimmingCharacters(in: .whitespacesAndNewlines)

private func getWatchName(model: String) -> String {
    switch model {
    case "Watch1,1":
        return "Apple Watch 38mm"
    case "Watch1,2":
        return"Apple Watch 42mm"
    case "Watch2,3":
        return "Apple Watch Series 2 38mm"
    case "Watch2,4":
        return "Apple Watch Series 2 42mmm"
    case "Watch2,6":
        return "Apple Watch Series 1 38mm"
    case "Watch2,7":
        return "Apple Watch Series 1 42mm"
    case "Watch3,1":
        return "Apple Watch Series 3 38mm Cellular"
    case "Watch3,2":
        return "Apple Watch Series 3 42mm Cellular"
    case "Watch3,3":
        return "Apple Watch Series 3 38mm"
    case "Watch3,4":
        return "Apple Watch Series 3 42mm"
    case "Watch4,1":
        return "Apple Watch Series 4 40mm"
    case "Watch4,2":
        return "Apple Watch Series 4 44mm"
    case "Watch4,3":
        return "Apple Watch Series 4 40mm Cellular"
    case "Watch4,4":
        return "Apple Watch Series 4 44mm Cellular"
    case "Watch5,1":
        return "Apple Watch Series 5 40mm"
    case "Watch5,2":
        return "Apple Watch Series 5 44mm"
    case "Watch5,3":
        return "Apple Watch Series 5 40mm Cellular"
    case "Watch5,4":
        return "Apple Watch Series 5 44mm Cellular"
    default:
        return "unknown"
    }
}

Just added the new models to the above based on this article
