虽然这个问题在2012年就被提出了，但苹果仍然没有给出将设备模式标识符转换为设备名称的方法。 有很多答案依赖于硬编码这些名称，不幸的是，当苹果发布新设备时，这些名称很快就过时了。

我们需要的是一种方法来获得一个不断更新的列表，它就在这里:https://github.com/ptrkstr/Devices

每次添加新设备时，这个Swift包都会更新，你所需要做的就是更新你的依赖项来获得它们。

兼容Swift 3

}

这个解决方案适用于物理设备和iOS模拟器，模拟器返回的模型与物理设备返回的模型相同。iPhone X (GSM)为iPhone10,6，而不是“x86_64”。

定义- Swift 4:

import UIKit

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)))
        }
        if let value = ProcessInfo.processInfo.environment["SIMULATOR_MODEL_IDENTIFIER"] {
            return value
        } else {
            return identifier
        }
    }
}

用法:

print(UIDevice.current.modelName)

为了节省别人的时间。 因为接受，必须投票回答建议库使用私人API和我的应用程序被拒绝，因为uidevice-extension就在昨天! 我切换到GBDeviceInfo库，安装为pod以及，现在它看起来不错，维护和更新到最新的设备。

对于那些不想使用Swift的Mirror的人，这里有一个使用普通类型的解决方案(也支持模拟器):

#if targetEnvironment(simulator)
@objc public protocol UIDevicePrivate {
    @objc func _deviceInfoForKey(_:String) -> Any?
}
#endif

extension UIDevice {
    var hardwareModel: String {
#if targetEnvironment(simulator)
        let privateSelf = unsafeBitCast(self, to:UIDevicePrivate.self)
        if let model = privateSelf._deviceInfoForKey("HWModelStr") as? String {
            return model + " (Simulator)"
        }
#endif
        var systemInfo = utsname()
        uname(&systemInfo)
        return String(characters: systemInfo.machine)
    }
}

一个从NSString描述中脱离的类别

通常，在整个代码中避免任意的字符串比较是可取的。最好在一个地方更新字符串，并在应用程序中隐藏神奇的字符串。为此，我在UIDevice上提供了一个类别。

对于我的特定需求，我需要知道我正在使用的设备，而不需要知道可以通过其他方式轻松检索的网络功能的细节。因此，您将发现一个比不断增长的设备列表更粗粒度的枚举。

更新就是将设备添加到枚举和查找表中。
