SPM 依赖项分支在 Xcode 13.3 和 Swift 5.6 上已弃用

Question

Xcode 13.3显示关于弃用外部包依赖项的警告。

例如：

// swift-tools-version:5.6
import PackageDescription

let package = Package(
    name: "MyPackage",
    platforms: [
        .iOS(.v15)
    ],
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyTarget"]),
    ],
    dependencies: [
        .package(
            name: "MyDependency", 
            url: "https://github.com/someorg/somepackage.git",
            .branch("main"))
    ],
    targets: [
        .target(
            name: "MyTarget",
            dependencies: ["MyDependency"])
    ]
)

这显示了警告：

'package(name:url:_:)' 已弃用：使用特定要求的 API 代替（例如，使用 'branch:' 代替 '.branch'）

但是，应用建议的更新会使依赖项无法再从MyPackage.

Answer 1

有必要将依赖项设置为产品。

具体来说.product(name: [PackageName], package: [Name of repository])，例如：

// swift-tools-version:5.6
import PackageDescription

let package = Package(
    name: "MyPackage",
    platforms: [
        .iOS(.v15)
    ],
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyTarget"]),
    ],
    dependencies: [
        .package(
            url: "https://github.com/someorg/somepackage.git",
            branch: "main")
    ],
    targets: [
        .target(
            name: "MyTarget",
            dependencies: [
                .product(
                    name: "MyDependency", 
                    package: "somepackage")])
    ]
)

更新

Xcode 14.3.1如果您有一个包含多个产品/库的包，这仍然相关。
