Ios 为什么可以'；我是否将SPM实用程序库作为依赖项包含在我的Package.swift中？

我想在我的项目中包括的实用程序库（SPM）

特定库在SPM的

包中定义。swift

如下：

   ...
   .library(
        name: "TSCUtility",
        targets: [
            "TSCclibc",
            "TSCLibc",
            "TSCBasic",
            "TSCUtility",
        ]
    ),
    ...

// swift-tools-version:5.0
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "ngfz",
    products: [
        .executable(
            name: "ngfz",
            targets: ["ngfz"]),
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        .package(url: "https://github.com/apple/swift-package-manager.git", from: "0.1.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            name: "ngfz",
            dependencies: ["TSCUtility"]),
        .testTarget(
            name: "ngfzTests",
            dependencies: ["ngfz"]),
    ]
)

当我构建项目时，出现以下错误：

swift build --product nfgz
'ngfz' /Users/nlykkei/Projects/ngfz: error: product dependency 'TSCUtility' not found
warning: dependency 'SwiftPM' is not used by any target

暗示图书馆找不到。但是，如果我将另一个SPM库作为依赖项，例如

SwiftPM

，那么一切正常吗

My Package.swift的定义如下：

   ...
   .library(
        name: "TSCUtility",
        targets: [
            "TSCclibc",
            "TSCLibc",
            "TSCBasic",
            "TSCUtility",
        ]
    ),
    ...

// swift-tools-version:5.0
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "ngfz",
    products: [
        .executable(
            name: "ngfz",
            targets: ["ngfz"]),
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        .package(url: "https://github.com/apple/swift-package-manager.git", from: "0.1.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            name: "ngfz",
            dependencies: ["TSCUtility"]),
        .testTarget(
            name: "ngfzTests",
            dependencies: ["ngfz"]),
    ]
)

就我所见，最后一个标记的版本是0.4.0，其中实用程序库仍然命名为

spmultility

。您可以通过声明对

master

分支的依赖关系来获取最新版本：

依赖项：[
.package（url:）https://github.com/apple/swift-package-manager.git“，.分公司（“主分公司”））
],

谢谢。因此，

.branch

针对的是一个特定的分支，其中as

.from

只针对标记版本，即具有指定标记的提交（每个提交可能没有标记）-我说得对吗？：-）
