I want to build a native macOS app named JSONFormatter using Xcode, Swift, and SwiftUI. Use the attached sketch as the visual reference for the application.

Do not write, modify, or generate any code yet.

First, inspect the existing Xcode project and then produce a staged implementation plan. The plan should be detailed enough that each stage can be completed, built, and manually verified before moving to the next stage.

App requirements:

Native macOS SwiftUI application
Two-pane layout

Project Context

Overview

iOS 26 SwiftUI app targeting iPhone and iPad
Minimum deployment: iOS 26
Swift 6 with strict concurrency
Uses SwiftUI throughout - no UIKit unless absolutely necessary

Architecture

Global Claude Code Instructions

Project Documentation Requirements

CLAUDE.md (Project Memory)

When starting work on a new Xcode project, if no CLAUDE.md exists in the project root, create one with:
