Environment Check

• Xcode CLI: !xcode-select -p 2>/dev/null && echo "✓" || echo "✗ Run: xcode-select --install"
• Homebrew: !brew --version 2>/dev/null | head -1 || echo "✗ Run: /bin/bash -c \"$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)\""
• Fastlane: !fastlane --version 2>/dev/null | grep -o "fastlane [0-9.]*" | head -1 || echo "✗ Run: brew install fastlane"

Your Project

• Project: !find . -maxdepth 2 -name "*.xcodeproj" 2>/dev/null | head -1 || echo "None found"
• Workspace: !find . -maxdepth 2 -name "*.xcworkspace" ! -path "*/.build/*" ! -path "*/xcodeproj/*" 2>/dev/null | head -1 || echo "None"

Step 1: Install Fastlane

brew install fastlane

Why Homebrew? Bundler 4.x broke Fastlane's Ruby dependencies. Homebrew avoids all version conflicts.

---

Step 2: Create Configuration Files

fastlane/Appfile

app_identifier("{{BUNDLE_ID}}")  # Your bundle ID
apple_id("{{APPLE_ID}}")         # Your Apple ID email
team_id("{{TEAM_ID}}")           # Your team ID

fastlane/Fastfile

default_platform(:ios)

platform :ios do
  desc "Run tests"
  lane :test do
    scan(scheme: "{{SCHEME}}")
  end

  desc "Upload to TestFlight"
  lane :beta do
    increment_build_number
    gym(scheme: "{{SCHEME}}", export_method: "app-store")
    pilot(skip_waiting_for_build_processing: true)
  end

  desc "Submit to App Store"
  lane :release do
    increment_build_number
    gym(scheme: "{{SCHEME}}", export_method: "app-store")
    deliver(submit_for_review: false, force: true)
  end
end

Replace {{SCHEME}} with your app's scheme name (usually the app name).

---

Step 3: Set Up Metadata (Optional)

Download your existing App Store listing:

fastlane deliver download_metadata
fastlane deliver download_screenshots

This creates fastlane/metadata/ with editable text files for your app description, keywords, etc.
