description	Migrates existing Xcode projects to Tuist generated workspaces with build and run validation, external dependency mapping, and migration checklists. Use when adopting Tuist for an existing app or converting a hand-edited Xcode project to generated projects.

Migrating to Tuist Generated Projects

Quick Start

1. Baseline build and run the app with xcodebuild.
2. Inventory targets, build settings, and external dependencies.
3. Create Tuist.swift, Project.swift, and Tuist/Package.swift.
4. Extract settings into .xcconfig files and wire them in Project.swift.
5. Generate and build: tuist generate --no-open then xcodebuild build.
6. Fix build issues, regenerate, and validate runtime on a simulator.

Preflight Checklist

• Primary app scheme and any extension/test schemes
• Targets list (app, extensions, tests, helper tools)
• Deployment targets and bundle identifiers
• Info.plist locations and entitlements
• Custom build settings (per target and per configuration)
• External dependencies (SPM, XCFrameworks, local packages)
• Build scripts (SwiftGen, Sourcery, codegen)
• Runtime validation plan (simulator destination and launch command)

Outputs

• Project.swift and Tuist.swift
• Tuist/Package.swift for external dependencies
• .xcconfig files (optional but recommended)
• Build and runtime validation notes
• A short migration log of decisions and fixes
