ios - Swift 包管理器混合语言源文件

Question

出于某种原因，当我尝试在我的 Package.swift 文件上运行 swift build 时:import PackageDescription

let package = Package(
    name: "mobile-HDISegurado-ios",
    dependencies: [
        .package(url: "https://github.com/watson-developer-cloud/swift-sdk", from: "0.30.0"),
        ],
    targets: [
        .target(
            name: "mobile-HDISegurado-ios",
            dependencies: ["WatsonDeveloperCloud"],
            path: "mobile-HDISegurado-ios",
            exclude: [
                "Config",
                "Public",
                "Resources",
                ]
        )
    ] )

我遇到了以下错误:

error: target at '.../mobile-HDISegurado-ios' contains mixed language source files; feature not supported

更多详情:

• swift package tools-version: 4.1.0
• 运行 Cocoapods 的项目工作区。

SPM 现在支持混合语言源文件，但您可能必须将它们分成多个目标。

来自 the relevant docs :

Targets can contain Swift, Objective-C/C++, or C/C++ code, but an individual target can’t mix Swift with C-family languages. For example, a Swift package can have two targets, one that contains Objective-C, Objective-C++, and C code, and a second one that contains Swift code.

在实践中，您应该将您的 ObjC/C/C++ 文件移动到一个目录，将您的 Swift 文件移动到另一个目录，然后这样修改您的 Package.swift:

products: [
    .library(
        name: "MyLibrary",
        targets: ["MyLibrarySwift", "MyLibraryObjC"]),
],
.target(name: "MyLibraryObjC",
        path: "Sources/MyLibraryObjC"
),
.target(name: "MyLibrarySwift",
        path: "Sources/MyLibrarySwift"
)
