SwiftUI Empty App Init

Overview

Initialize a clean, single-target SwiftUI iOS app in the current directory. The project is generated using XcodeGen to produce a single .xcodeproj, leaving developers ready to start adding features immediately.

Prerequisites

• Xcode installed and selected via xcode-select
• XcodeGen available on PATH

If any prerequisite is missing:

• Stop execution
• Tell the user exactly what is missing
• Do not attempt alternative scaffolding or auto-installation

Inputs

• Project name (required)
• Minimum iOS deployment target
• Optional bundle identifier (or use default)

Defaults (use without extra confirmation)

• Bundle identifier default: com.example.<ProjectName>
• Proceed immediately once required inputs are provided (do not ask extra confirmations)

Core Requirements

The resulting project must:

• Be generated via XcodeGen (do not hand-author project.pbxproj)
• Use a single .xcodeproj (no .xcworkspace)
• Contain exactly one app target
• Use the SwiftUI @main App lifecycle
• Contain a minimal ContentView placeholder
• Contain a minimal Info.plist (avoid unnecessary scene or delegate keys)
• Contain no Swift packages
• Contain no test targets unless explicitly requested

Generation

• Create a minimal project.yml using the provided inputs
• Generate YourApp.xcodeproj using XcodeGen
• Ensure the output matches all Core Requirements

Expected Structure

• project.yml
• YourApp.xcodeproj
• YourApp/ (app target source files)
• Optional config files only

No additional folders, packages, workspaces, scripts, or assets should be present.

Minimal Verification (fast)

• Confirm YourApp.xcodeproj is generated successfully by XcodeGen.
• Confirm the default scheme exists (e.g., via a lightweight scheme listing).
• Do not boot simulators, build, install, or launch unless explicitly requested.

Notes

• Keep the project minimal and unopinionated
• Do not add icons/scripts, packages, workspaces, or architecture scaffolding
• This skill is for app initialization only, not feature scaffolding
