Swift 4或更高版本

extension UIDevice {
    var modelName: String {
        if let modelName = ProcessInfo.processInfo.environment["SIMULATOR_MODEL_IDENTIFIER"] { return modelName }
        var info = utsname()
        uname(&info)
        return String(String.UnicodeScalarView(
                   Mirror(reflecting: info.machine)
                    .children
                    .compactMap {
                        guard let value = $0.value as? Int8 else { return nil }
                        let unicode = UnicodeScalar(UInt8(value))
                        return unicode.isASCII ? unicode : nil
                    }))
    }
}

UIDevice.current.modelName   // "iPad6,4"

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。

设备名称和机器名称，基于iOS真实设备硬件

我对这个问题的解决方案基本上看起来与这个帖子中的@NicolasMiari的答案有关。单独的实用程序类具有一组预定义的设备名和机器名，然后根据实际的机器名检索设备名。

注:此答案及其链接的GitHub项目已更新，以识别截至2017年10月的最新iPhone (iPhone 8, 8+， X)。这也适用于iOS11。请访问GitHub回购和看到，并给我反馈，如果有什么错误。

我已经在一个类中添加了这个实现和其他一些方便的实用工具方法，并把它放在这个GitHub存储库中。你也可以在这个Wiki页面中找到最新的设备信息列表。

请访问并使用它。

更新:

您可能需要导入sys框架，

#import <sys/utsname.h>

以下是Aniruddh基于uname的方法的现代版本，它不依赖于Mirror，应该适用于Swift 4.2及更高版本:

import UIKit

extension UIDevice {
  var machineName: String {
    var info = utsname()
    return withUnsafeMutablePointer(to: &info) { info in
      // We could alternatively return nil here, or handle
      // errors some other way.
      guard uname(info) == 0 else { return model }
      let offset = MemoryLayout.offset(of: \utsname.machine)!
      let machine = UnsafeRawPointer(info).advanced(by: offset).assumingMemoryBound(to: CChar.self)
      return String(cString: machine)
    }
  }
}

使用ideviceinfo获取这些值怎么样?应该能够安装它使用brew安装ideviceinfo

然后运行:

PRODUCT_NAME=$(ideviceinfo --udid $DEVICE_UDID --key ProductName)
PRODUCT_TYPE=$(ideviceinfo --udid $DEVICE_UDID --key ProductType)
PRODUCT_VERSION=$(ideviceinfo --udid $DEVICE_UDID --key ProductVersion)
