How to get hardware details in Swift?
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<

Heres HAS' extension that I modified to get the processor and speed from UIDevice. Probably not the best way (all the values are hardcoded) but it works!
import Foundation import NotificationCenter public extension UIDevice { //Original Author: HAS // https://stackoverflow.com/questions/26028918/how-to-determine-the-current-iphone-device-model // Modified by Sam Trent /********************************************** * getCPUName(): * Returns a hardcoded value of the current * devices CPU name. ***********************************************/ public func getCPUName() -> String { var processorNames = Array(CPUinfo().keys) return processorNames[0] } /********************************************** * getCPUSpeed(): * Returns a hardcoded value of the current * devices CPU speed as specified by Apple. ***********************************************/ public func getCPUSpeed() -> String { var processorSpeed = Array(CPUinfo().values) return processorSpeed[0] } /********************************************** * CPUinfo: * Returns a dictionary of the name of the * current devices processor and speed. ***********************************************/ private func CPUinfo() -> Dictionary<String, String> { #if (arch(i386) || arch(x86_64)) && os(iOS) 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?

print(UIDevice.current.getCPUName()) print(UIDevice.current.getCPUSpeed())讨论(0) -
Most of this stuff can be revealed with some of the lower level C APIs. This might be a good opportunity for you to write some simple Swift extensions based on them, but you can write C code directly in Swift to get your answers anyway.
I would love to take credit but I'll just link to some answers other people have provided:
- Process info
- SystemKit
- DeviceGuru (in swift!)

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<String, String> { #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?
