我刚开始使用 swift 3 并使用 Swift 3.0 在 xcode 中制作了一个简单的应用程序。现在我想使用 Swift Package Manager添加第三方库。我正在遵循此链接中给出的安装方法。我创建了Package.swift看起来像这样的文件
import PackageDescription
let package = Package (
name : "SwiftPM",
dependencies : [
.Package(url: "https://github.com/ArtSabintsev/Siren.git", majorVersion: 1)
])

The Swift Package Manager and Xcode are orthogonal. That is, you can't expect to compile Package.swift in Xcode; it simply won't work. Instead, until Xcode supports the package manager, you need to have two distinct builds - one with the package manager and one with Xcode.
Swift Package Manager 和 Xcode 是正交的。也就是说，你不能指望在 Xcode 中编译 Package.swift；它根本行不通。相反，在 Xcode 支持包管理器之前，您需要有两种不同的构建——一种带有包管理器，一种带有 Xcode。
So, using the Swift Package Manager, once you've defined Package.swift and formulated your directory structure as expected by the package manger, you perform simply:
因此，使用 Swift 包管理器，一旦您定义了 Package.swift 并按照包管理器的预期制定了目录结构，您只需执行以下操作：
swift build
Then for Xcode, you create an Xcode project that uses your source code, but not Package.swift. You'll need to clone the Siren.git project, explicitly - into your Xcode build's source files.
然后对于 Xcode，您创建一个使用源代码的 Xcode 项目，但不使用 Package.swift。您需要将 Siren.git 项目明确地克隆到您的 Xcode 构建的源文件中。
