在本章的其余部分，我们将切换平台并看看如何构建相同的应用程序，尤其是在
iOS 上！
3.2
为
iOS
构建人脸检测器应用程序
现在让我们探索如何使用 ML Kit 的人脸检测为 iOS 构建一个非常相似的应用程序。对于
iOS，你需要使用 Mac 计算机作为开发机器，以及用于编码、调试和测试的 Xcode 环境。
3.2.1
第
1
步：在
Xcode
中创建项目
首先，启动 Xcode 并选择 New Project。你将看到新的项目模板对话框，如图 3-10 所示。

：新的项目模板对话框
确保你在屏幕顶部选择 iOS，然后选择 App 作为应用程序类型。单击 Next（下一步），
系统会要求你填写一些详细信息。保留除项目名称外的所有默认值，我称它为 firstFace，
但这取决于你使用的名称。Interface 项选择 Storyboard，Life Cycle 项选择 UIKit App
Delegate，Language 项选择 Swift，如图 3-11 所示。
单击 Next 后，Xcode 将为你创建一个模板项目。此时你应该关闭 Xcode，因为在开始编
码之前你需要在 IDE 之外进行一些配置。你将在下一步使用 CocoaPods 添加 ML Kit 库
时看到这一点。
