  2. Xcodeプロジェクト内のターゲット間 の依存関係 • App.xcworkspace > App.xcproj > project.pbxproj > PBXTarget

    > PBXNativeTarget > dependencies http://www.monobjc.net/xcode-project-file-format.html
  3. • App.xcworkspace > App.xcproj > project.pbxproj > PBXTarget > PBXNativeTarget

    > dependencies 491FBA866697560BBEF6A475 /* PBXTargetDependency */ = { isa = PBXTargetDependency; target = 3478A70B9E3147C13F640454 /* AModule */; }; 4C4FDDD28591957330786D9B /* App */ = { isa = PBXNativeTarget; dependencies = ( 491FBA866697560BBEF6A475 /* PBXTargetDependency */ ); } http://www.monobjc.net/xcode-project-file-format.html Xcodeプロジェクト内のターゲット間 の依存関係
  4. • App.xcworkspace > App.xcproj > project.pbxproj > PBXTarget > PBXNativeTarget

    > dependencies 491FBA866697560BBEF6A475 /* PBXTargetDependency */ = { isa = PBXTargetDependency; target = 3478A70B9E3147C13F640454 /* AModule */; }; 4C4FDDD28591957330786D9B /* App */ = { isa = PBXNativeTarget; dependencies = ( 491FBA866697560BBEF6A475 /* PBXTargetDependency */ ); } http://www.monobjc.net/xcode-project-file-format.html Xcodeプロジェクト内のターゲット間 の依存関係
  5. ターゲットとSwift Package間の依存 4C4FDDD28591957330786D9B /* AModule */ = { isa =

    PBXNativeTarget; packageProductDependencies = ( 1885F5AAE69D8D13E59C4ECF /* BModule */, ); }; http://www.monobjc.net/xcode-project-file-format.html • App.xcworkspace > App.xcproj > project.pbxproj > PBXTarget > PBXNativeTarget > packageProductDependencies
  6. Swift Package 内でのターゲット間の 依存 • $ swift package dump-package {

    "targets": [ { "dependencies": [ { "byName": ["CModule", null] } ], "name": "BModule" } ] }
  7. XcodeSelectiveTesting • $ swift run xcode-selective-testing --test-plan App.xctestplan • $

    swift run xcode-selective-testing --json https://github.com/mikeger/XcodeSelectiveTesting

    "testTarget": true }, { "name": "App", "type": "target", "path": "\/path\/to\/your\/App.xcodeproj", "testTarget": false } ]
  9. JSON Output [ { "name": "AppTests", "type": "target", "path": "\/path\/to\/your\/App.xcodeproj",

    "testTarget": true }, { "name": "App", "type": "target", "path": "\/path\/to\/your\/App.xcodeproj", "testTarget": false } ] $ jq -r "[.[] | select(.testTarget == true)] | map(.name) | join(\",\")"

    "testTarget": true }, { "name": "App", "type": "target", "path": "\/path\/to\/your\/App.xcodeproj", "testTarget": false } ] $ jq -r "[.[] | select(.testTarget == true)] | map(.name) | join(\",\")" AppTests

    parameter is invalid or missing.") end if options[:targets].empty? then UI.user_error!("At least one target is required.") end run_tests( scheme: "...", only_testing: options[:targets], ) end
