ios - 快速构建 : warning: '--product' cannot be used with the automatic product 'ProductName' ; building the default target instead

Question

我有一个 Package.swift list 如下:

// swift-tools-version:5.4
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "long-package-name-ios",
    defaultLocalization: "en",
    platforms: [
        .iOS(.v14),
        .macOS(.v10_15)
    ],
    products: [
        .library(
            name: "PackageName",
            targets: ["PackageName"]),
        .library(
            name: "PackageNameImproved",
            targets: ["PackageNameImproved"]),
        .library(
            name: "PackageNameUI",
            targets: ["PackageNameUI"]),
    ],
    dependencies: [
        .package(
            name: "PackageLib",
            url: "ssh://apple.com/packagelib.git",
            .upToNextMinor(from: "1.2.3")
        )
    ],
    targets: [
        .target(
            name: "PackageName",
            dependencies: [
                .product(name: "PackageLib", package: "PackageLib"),
            ],
            path: "PackageName"),
        .target(
            name: "PackageName",
            dependencies: [
                "PackageName",
                .product(name: "PackageLib", package: "PackageLib"),
            ],
            path: "PackageNameImproved"),
        .target(
            name: "PackageNameUI",
            dependencies: [
                "PackageNameImproved",
            ],
            path: "PackageNameUI")
    ]
)

包 list 摘要:

• 3 个目标
• 一个目标依赖于另一个目标
• 只有 PackageName 兼容 macOS，其他都是 iOS-only

构建命令

为 iOS 构建 long-package-name-ios-Package(构建包内的所有目标):

swift build -Xswiftc "-sdk" -Xswiftc "$(xcrun --sdk iphonesimulator--show-sdk-path)" -Xswiftc "-target" -Xswiftc "arm64-apple-ios15.0-simulator"

[137/137] Build complete!

现在尝试为 macOS 构建 PackageName:

swift build -Xswiftc "-sdk" -Xswiftc "$(xcrun --sdk macosx--show-sdk-path)" --product "PackageName"

[1/1] Planning buildwarning: '--product' cannot be used with theautomatic product 'PackageName'; building the default target instead

然后它继续为 macOS 平台构建默认目标 long-package-name-ios-Package 显然由于无法导入而失败，例如UIKit 或任何其他仅限 iOS 的框架。

问题

如何指定只为 macOS 平台构建 PackageName？我愿意创建 Xcode 包、方案和其他不同的配置，但最终目标应该是:

1. 仅针对 iOS 集成 long-package-name-ios-Package(所有目标)
2. 为 macOS 集成 PackageName

Answer 1

编辑:虽然我最初的回答使错误消失了，但实际上无法将库导入插件。 (它无法编译并出现“没有这样的模块”错误。)这 seems成为预期的行为。

错误中的“自动产品”指的是PackageName没有配置库类型。如果您配置它的类型(dynamic 或 static)，错误就会消失并且可以构建目标:

.library(
  name: "PackageName",
  type: .dynamic,
  targets: ["PackageName"]
)
