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, NSProcessInfo. I saw several posts but I don't find any solving.

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:

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

You can use it like this:
print(UIDevice.current.getCPUName())
print(UIDevice.current.getCPUSpeed())
Here is the list of updated CPU info from apple. Even though its hardcoded it will work fine until 2021's fall :)

return identifier + String(UnicodeScalar(UInt8(value)))
