ios 获取手机设备型号设备比如iphone8 iphone7 到iphone 15 swift

可以使用UIDevice类来获取设备的型号。以下是一个示例代码：

import UIKit

func getDeviceModel() -> 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 "iPhone1,1": return "iPhone 1G"
    case "iPhone1,2": return "iPhone 3G"
    case "iPhone2,1": return "iPhone 3GS"
    case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
    case "iPhone4,1": return "iPhone 4S"
    case "iPhone5,1", "iPhone5,2": return "iPhone 5"
    case "iPhone5,3", "iPhone5,4": return "iPhone 5C"
    case "iPhone6,1", "iPhone6,2": return "iPhone 5S"
    case "iPhone7,2": return "iPhone 6"
    case "iPhone7,1": return "iPhone 6 Plus"
    case "iPhone8,1": return "iPhone 6S"
    case "iPhone8,2": return "iPhone 6S Plus"
    case "iPhone8,4": return "iPhone SE"
    case "iPhone9,1", "iPhone9,3": return "iPhone 7"
    case "iPhone9,2", "iPhone9,4": return "iPhone 7 Plus"
    case "iPhone10,1", "iPhone10,4": return "iPhone 8"
    case "iPhone10,2", "iPhone10,5": return "iPhone 8 Plus"
    case "iPhone10,3", "iPhone10,6": return "iPhone X"
    case "iPhone11,2": return "iPhone XS"
    case "iPhone11,4", "iPhone11,6": return "iPhone XS Max"
    case "iPhone11,8": return "iPhone XR"
    case "iPhone12,1": return "iPhone 11"
    case "iPhone12,3": return "iPhone 11 Pro"
    case "iPhone12,5": return "iPhone 11 Pro Max"
    case "iPhone12,8": return "iPhone SE (2nd generation)"
    case "iPhone13,1": return "iPhone 12 mini"
    case "iPhone13,2": return "iPhone 12"
    case "iPhone13,3": return "iPhone 12 Pro"
    case "iPhone13,4": return "iPhone 12 Pro Max"
    default: return identifier
    }
}

let deviceModel = getDeviceModel()
print(deviceModel)

该代码将返回类似"iPhone 8"或"iPhone X"的设备型号字符串。请注意，这个列表可能需要根据新发布的设备型号进行更新。
