Tuist Workspace Navigator

Before invoking Apple-only binaries, confirm the execution context is macOS. From Windows or Linux, run those steps in a Mac SSH project or through an already configured remote transport; do not retry missing Apple binaries locally.

Use this skill for day-to-day development in projects where Tuist owns the Xcode workspace.

Defaults

• Run generation non-interactively:

  tuist generate --no-open
  

• Build and test with xcodebuild against the generated workspace.
• Regenerate after manifest, dependency, target graph, or resource layout changes.
• Run tuist install before generation when package dependencies changed.

Focused Generation

Prefer smaller generated graphs when working on one feature or target:

tuist generate AppFeature AppFeatureTests --no-open
tuist generate tag:feature:payments --no-open

Use target tags consistently for teams, layers, and features so agents can scope generation and testing without guessing target names.

Manifest Guidance

• Prefer file-system-synchronized buildable folders when the project uses them; keep paths aligned with the real source tree.
• Do not overlap broad source/resource globs with buildable folders.
• Keep build configurations aligned between local targets and external dependencies.
• Treat .intentdefinition as source and avoid double-including localization files such as .xcstrings, .strings, and .stringsdict.
• Keep package product type overrides deliberate; making every dependency dynamic can hide linker problems and hurt launch time.

Build

xcodebuild build \
  -workspace App.xcworkspace \
  -scheme App \
  -destination "platform=iOS Simulator,name=<available iPhone simulator>,OS=latest"

Test

Prefer narrow xcodebuild test selectors for iteration:

xcodebuild test \
  -workspace App.xcworkspace \
  -scheme AppTests \
  -only-testing AppTests/MySuite/testExample

If a narrow selector runs zero tests, broaden to the suite or target and report that the selector did not match.

Troubleshooting

• Missing products: run tuist install, then regenerate.
• Type not found: check excluded source folders and generated files.
• Resource not found at runtime: inspect resource globs and package resources.
• Undefined symbols: verify SDK dependencies and product type overrides.
• Objective-C category crash: add -ObjC or targeted -force_load where the consuming target needs it.

Report the generated workspace path, scheme, command, and final build/test result.
