Trivial Swift Package 通过 XCode 构建，但不是通过 'swift build' 构建的 - 后者抱怨缺少 .h 头文件

Question

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

https://drive.google.com/file/d/1dqjJACKX1cIVUk-cwxZxOEd8taKAU1i3/view?usp=share_link

我的包很简单:

// 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'ios-nrf-connect-device-manager'没有被任何目标使用，然后它编译失败

给了什么?

Answer 1

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。

您需要确保包名匹配，并显式地将McuManager添加为目标的依赖项。

将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"]
)
]
)
