在尝试根据第三方框架构建基于Swift的命令行工具时构建错误：此目标可能包含其自己的产品

Question

上下文：我想使用CryptoSwift创建一个简单的Swift命令行工具 我对Xcode和Swift（以及MacOS！）相对较新。

配置：
- MacOS High Sierra 10.13.2
- Xcode：9.2

步骤：

1. 我启动Xcode
2. 为MacOS创建一个新项目“命令行工具”
3. 我的项目选项：
   • 产品名称：cryptodemo
   • 组织标识符：com.demo
   • Language Swift
4. 我将项目创建为~/Documents

5. 将main.swift填入：

   import Foundation
   import CryptoSwift
   
   print("Hello, World!")
   
   let bytes:Array<UInt8> = [0x01, 0x02, 0x03]
   let digest = Digest.md5(bytes)
   

6. 打开shell并进入~/Documents/cryptodemo

7. 使用git submodule add https://github.com/krzyzanowskim/CryptoSwift.git
将CryptoSwift添加为project’s README定义的子模块
8. 打开Finder并将CryptoSwift.xcodeproj文件拖到我的Xcode项目
中

9. 在Xcode中，我进入我的项目Build Phase

   • 我添加了CryptoSwift作为目标依赖项
   • 我将CryptoSwift.framework添加到Link Binaries with Libraries
   • 我向CryptoSwift.framework添加了Copy Files：
     • 目的地：Framework
     • SubPath :(空）

10. 然后我建立它。我有这个错误：

    Check dependencies
    
    Unable to run command 'PBXCp CryptoSwift.framework' - this target might include its own product.
    Unable to run command 'CodeSign A' - this target might include its own product.

Answer 1

删除第9步并将CryptoSwift.framework添加到“链接的框架和库”

Answer 2

我设法使用第三方Swift库构建命令行工具的唯一方法是使用Swift Package Manager (SPM)。

使用SPM的Swift项目示例（可以使用Process: Xcode [70544] Path: /Applications/Xcode.app/Contents/MacOS/Xcode Identifier: com.apple.dt.Xcode Version: 9.3 (14154) Build Info: IDEFrameworks-14154000000000000~2 App Item ID: 497799835 App External ID: 826408812 Code Type: X86-64 (Native) Parent Process: ???

swift package init --type executable

可以使用以下命令从此SPM生成Xcode项目：// swift-tools-version:4.0 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: “mytool”, dependencies: [ .package(url: "https://github.com/myfreeweb/SwiftCBOR.git", .branch("master")), ], 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: “mytool”, dependencies: [ "SwiftCBOR" ]), ] )
