dyld: Library not loaded: @rpath/FilesProvider.framework/Versions/A/FilesProvider

结论：cocoa pods不支持Command Line Tool项目

Cocoapods + Command Line Tool - dyld: Library not loaded: @rpath/Realm.framework/Versions/A/Realm cocoa pods不支持Command Line Tool项目 Command Line Tool + CocoaPods frameworks breaks

采用SPM来管理依赖库

  1. 使用SPM创建可执行模版

2

$ mkdir SPMCmdLineTool
$ swift package init --type=executable
  1. 配置Package.swift

import PackageDescription
let package = Package(
    name: "SPMCmdLineTool",
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
        .package(path: "/Users/admin/hsg/FileProvider")
    ],
    .target(
        name: "SPMCmdLineTool",
        dependencies: ["FilesProvider"]),
        
    .testTarget(
        name: "SPMCmdLineToolTests",
        dependencies: ["SPMCmdLineTool"]),
    ]
)
  1. 使用workspace管理 先生成一个Xcode工程文件：SPMCmdLineTool.xcodeproj
1

$ swift package generate-xcodeproj

再把SPMCmdLineTool.xcodeproj拖入现有的workspace中来管理。

每次执行swift build ，须重新生成xcodeproj工程文件，再重新打开workspace即可。
