使用Swift Package Manager时，跨测试目标共享代码

Question

在使用Swift Package Manager时，我有一些代码需要在测试目标之间共享。为此，我有一个.testTarget，我也将其命名为另一个.ttestTarget.中的依赖项

这里有一个简单的例子：

// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "ExampleLib",
products: [
// Products define the executables and libraries a package produces, and make them visible to other packages.
.library(
name: "ExampleLib",
targets: ["ExampleLib"]),
],
dependencies: [
// Dependencies declare other packages that this package depends on.
// .package(url: /* package url */, from: "1.0.0"),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages this package depends on.
.target(
name: "ExampleLib",
dependencies: []),
.testTarget(
name: "Common",
dependencies: ["ExampleLib"]),
.testTarget(
name: "ExampleLibTests",
dependencies: ["Common"]),

]
)

如果我试图在Xcode中构建这个包，我会得到以下错误：

Unable to resolve build file: XCBCore.BuildFile (The workspace has a reference to a missing target with GUID 'PACKAGE-TARGET:Common')

但是，如果我从命令行(swift build(构建或从命令行进行测试(swift test(，我就会成功。

我使用的是Xcode 12 beta 6，但也尝试过Xcode 11.5(对Package.swift标头进行了更改(，并得到了相同的结果。

以下是完整的Swift软件包示例：https://www.dropbox.com/s/h6ypvbfonnb2zyk/ExampleLib.zip?dl=0

我真的很想在Xcode中使用它来构建iOS。想法？

我遇到了同样的问题，并通过为Common定义目标(而不是测试目标(来解决它。

我的Package.swift文件：

// ...
.target(name: "Common", dependencies: ["App"], path: "Tests/Common"),
.testTarget(name: "AppTests", dependencies: ["App", "Common"]),
.testTarget(name: "IntegrationTests", dependencies: ["App", "Common"])
// ...
