📦 Comprehensive Packaging Guide

Why Packaging Matters

Distributing SwiftUI applications requires converting source code into standalone .app bundles. Essential requirements:

  • 「Full Xcode installation」 (command-line tools insufficient)
  • 「Xcode 15.0+」 recommended

Environment Setup

  1. Install Xcode from Mac App Store (~15GB download)
  2. Accept license agreement upon first launch
  3. Configure developer tools path:

    sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
  4. Verify installation:

    xcode-select --print-path
# Correct output: /Applications/Xcode.app/Contents/Developer

Packaging Method 1: Automated Script

# 1. Grant execution permission
chmod +x build_app.sh

# 2. Execute build script
./build_app.sh

# 3. Locate output files
#   Application: build/Export/TypeTranslator.app
#   Installer: build/TypeTranslator-v1.0.dmg

Packaging Method 2: Manual Xcode Process

  1. Open project: open TypeTranslator.xcodeproj
  2. Configure signing:

    • Project settings > Signing & Capabilities
    • Disable “Automatically manage signing”
    • Add Apple Developer account if available
  3. Build archive:

    • Select Product > Archive
    • Wait 2-5 minutes for completion
  4. Export application:

    • In Organizer window, click “Distribute App”
    • Choose “Copy App” for local distribution
    • Select output destination

Troubleshooting Packaging Issues

Symptom Solution
Code signing errors Disable auto-signing, select “Sign to Run Locally”
Swift compilation failures Use Product > Clean Build Folder
Permission request failures Verify Info.plist and .entitlements files
Incorrect Xcode path Reset with xcode-select --switch

Distribution & Technical Support

Application Distribution Channels

  • 「Individual sharing」: Direct .app transfer (recipients must right-click > Open)
  • 「Developer distribution」:

    • Notarization for security approval
    • Mac App Store submission
