How to get hardware details in Swift?

Question

How to get info of hardware like CPU Model, CPU usage, CPU idle, RAM Details, Storage details etc? I use Xcode 7.1.1 and Swift 2. I want no make app. I tried UIDevice<

Here is the list of updated CPU info from apple. Even though its hardcoded it will work fine until 2021's fall :)

    private func CPUinfo() -> Dictionary {
    #if targetEnvironment(simulator)
    let identifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"]!
    #else
    
    var systemInfo = utsname()
    uname(&systemInfo)
    let machineMirror = Mirror(reflecting: systemInfo.machine)
    let identifier = machineMirror.children.reduce("") { identifier, element in
        guard let value = element.value as? Int8 , value != 0 else { return identifier }
        return identifier + String(UnicodeScalar(UInt8(value)))
    }
    #endif

     switch identifier {
