Swift Package Manager未分配依赖项

Question

我正在尝试使用Swift Package Manager为iOS创建一个软件包。

我有一个Package.swift，看起来像这样-

import PackageDescription

let package = Package(
    name: "MyPackage",
    platforms:  [.iOS(.v12)],
    products: [
        .library(name: "MyPackage", targets: ["MyPackage"]),
    ],
    dependencies: [
        .package(url: "https://github.com/yannickl/AwaitKit", from: "5.0.0"),
        .package(url: "https://github.com/kishikawakatsumi/KeychainAccess", from: "4.0.0"),
        .package(url: "https://github.com/OAuthSwift/OAuthSwift", from: "2.0.0")
    ],
    targets: [
        .target(name: "MyPackage", dependencies: []),
        .testTarget(name: "MyPackageTests", dependencies: ["MyPackage"]),
    ]
)

但是我的项目没有构建，引用这些依赖项的类说它们不存在，而且我在Xcode中也得到警告，没有使用这些依赖项的目标。

我尝试如下更新targets-

     targets: [
            .target(name: "MyPackage", dependencies: ["AwaitKit","KeychainAccess","OAuthSwift"]),
            .testTarget(name: "MyPackageTests", dependencies: ["MyPackage"]),
        ]

但这没什么区别吗？
