自动生成 iOS identifier 对应型号名称

数据收集、请求之类的一般都需要带上手机的型号，每次更新这个文件都需要各种地方查找型号同获取的型号码对应关系，总是感觉不太方便。
查找的时候发现一个比较好的方式是通过一个网址https://www.theiphonewiki.com/wiki/Models来进行对应。写了两行之后感觉这么看对眼睛不太好，因此写了个脚本来实现自动生成文件。

脚本地址 https://gitee.com/xo1988/ios-modelname/blob/master/analysis.py
目前只生成了，iPod、iPhone、iPad三个型号的，其他按需修改脚本生成。

生成方法：

python analysis.py

oc使用方法：

UIDevice.currentDevice.modelName

swift使用方法：

UIDevice.current.modelName

生成结果如下：

import Foundation
@objc
public extension UIDevice {
    var modelName: String {
        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)))
        }
        
        switch identifier {
        case "iPad1,1"             return "iPad"
