ios Trivial Swift Package通过XCode构建，但不通过“swift build”构建-后者抱怨缺少.h头文件

基本上就是主题所说的（我是Swift生态系统的新手）。你可以在这里下载完整的包：

我的方案相当简单：

// swift-tools-version:5.3

import PackageDescription

let package = Package(
    name: "McuMgr.Bindings.iOS",
    platforms: [.iOS(.v9), .macOS(.v10_13)],
    products: [
        .library(
            name: "McuMgr.Bindings.iOS",
            targets: ["McuMgr.Bindings.iOS"]
        ),
    ],
    dependencies: [
        .package(
            name: "McuMgr",
            url: "https://github.com/Laerdal/IOS-nRF-Connect-Device-Manager.git",
            .exact("0.13.0")
        ),
    ],
    targets: [
        .target(
            name: "McuMgr.Bindings.iOS",
            path: "Source",
            exclude:["Info.plist"]
        )
    ]
)

但是“swift build”抱怨依赖项“ios-nrf-connect-device-manager”未被任何目标使用，因此无法编译

怎么回事？

在你的代码中，你有import McuManager，但是你的Package.swift没有定义一个名为McuManager的包或依赖项。
您需要确保包名称匹配，并显式添加McuManager作为目标的依赖项。
将您的Package.swift更新为

// swift-tools-version:5.3

import PackageDescription

let package = Package(
    name: "Laerdal.McuMgr.Bindings.iOS",
    platforms: [.iOS(.v9), .macOS(.v10_13)],
    products: [
        .library(
            name: "Laerdal.McuMgr.Bindings.iOS",
            targets: ["Laerdal.McuMgr.Bindings.iOS"]
        ),
    ],
    dependencies: [
        .package(
            name: "McuManager", // << updated package name
            url: "https://github.com/Laerdal/IOS-nRF-Connect-Device-Manager.git",
            .exact("0.13.0")
        ),
    ],
    targets: [
        .target(
            name: "Laerdal.McuMgr.Bindings.iOS",
            dependencies: ["McuManager"], // << added depedency
            path: "Source",
            exclude:["Info.plist"]
        )
    ]
)
