Swift: get the Mac UUID

getMacUUID.swift

func getSystemUUID() -> String? {
    let dev = IOServiceMatching("IOPlatformExpertDevice")
    let platformExpert: io_service_t = IOServiceGetMatchingService(kIOMasterPortDefault, dev)
    let serialNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert, kIOPlatformUUIDKey, kCFAllocatorDefault, 0)
    IOObjectRelease(platformExpert)
    let ser: CFTypeRef = serialNumberAsCFString.takeUnretainedValue()
    if let result = ser as? String {
        return result
    }
    return nil
}

if let uuid = getSystemUUID() {
    print(uuid)
}

thank you!

if let result = ser as? String {
    return result
}
return nil

you could simply : return ser as? String

thank you!
