iOS Merchant Feature Declaration

Interactively declare new Feature cases in the iOS app by collecting all necessary information via a form, then automatically updating all required files across Domain and Presentation layers.

When to Activate

• "add new feature"
• "declare new feature"
• "create feature case"
• "add feature to menu"
• "new feature declaration"
• "register new feature"

Interactive Process

Step 1: Collect Feature Details

Use AskUserQuestion to collect all necessary information in a single form:

Required Information:

1. Feature name (camelCase, e.g., "balanceHistory")
2. Vietnamese description (e.g., "Lịch sử số dư")
3. English description (e.g., "Balance History")
4. Permission code (optional 5-digit number from backend, or empty if no permission)
5. Category placement (select from available categories)
6. Has icon? (yes/no)

Conditional Information:

• If has icon: Icon name (kebab-case, e.g., "balance-history-icon")
• Needs deep linking? (yes/no)
• If needs deep linking: Deep link path (e.g., "balance/history")

Available Categories:

• counterService - Counter services (home screen)
• onlineServices - Online services (home screen)
• utilityServices - Utility services (home screen)
• leftAccountCategories - Account section (side menu)
• leftCounterCategories - Counter section (side menu)
• leftOnlineCategories - Online section (side menu)
• leftUtilityCategories - Utility section (side menu)
• leftInstallmentConversionCategories - Installment section (side menu)
• none - No category (internal feature)

Step 2: Validate Inputs

Before proceeding, validate:

• Feature name is camelCase (first letter lowercase)
• Permission code is empty OR 5-digit number
• Category is valid
• Icon name (if provided) is kebab-case
• Deep link path (if provided) follows format: [category]/[feature]

If validation fails, show errors and ask user to correct.

Step 3: Update Domain Files

Update these files automatically using Edit tool:

3.1 Feature.swift (5 locations)

File: Domain/Model/Others/Feature.swift

Location 1: Add feature case (in appropriate section with comment) Location 2: Add permission code in code computed property Location 3: Add FeatureInfo mapping in getInfo() method Location 4: Add to category array (if category specified) Location 5: Add identifier in identifier computed property

Use templates from templates.md.

3.2 FeatureInfo.swift

File: Domain/Model/Others/FeatureInfo.swift

Add static property with icon and localized title (only if has icon). Use template from templates.md.

3.3 Localization Files

Files:

• PayooMerchant/Resources/Localization/vi.lproj/Localizable.strings
• PayooMerchant/Resources/Localization/en.lproj/Localizable.strings

Add localization keys:

• menu.label.[feature-name-kebab] - For menu items
• home.label.feature-[feature-name-kebab] - For home screen

Use append approach to avoid breaking existing content.

Step 4: Update Deep Linking (if needed)

If deep linking is enabled:

4.1 ScreenID.swift

File: Domain/Model/Setting/ScreenID.swift

Add screen ID case with deep link path.

4.2 Route.swift

File: PayooMerchant/Library/DeepLink/Route.swift

Add route case and URL mapping (4 locations: enum case, init URL mapping, Equatable, getPermissionFeature).

Use templates from templates.md.

Step 5: Update Presentation Layer Files (CRITICAL)

IMPORTANT: These files have exhaustive switch statements and MUST be updated to avoid compilation errors.

5.1 DeepLinkNavigator.swift

File: PayooMerchant/Library/DeepLink/DeepLinkNavigator.swift

Add case to getViewController(from destination:) switch statement.

• Return placeholder (e.g., makeHomeViewController()) until actual controller is implemented
• Add TODO comment for future implementation

5.2 Feature+Ext.swift

File: PayooMerchant/Models/Feature+Ext.swift

Add to navigationBarTitle computed property:

• If feature has navigation bar title: add specific case
• If no navigation bar title: add to nil-returning cases list

5.3 AppDelegateViewModel.swift

File: PayooMerchant/AppDelegateViewModel.swift

Add to route filtering switch (around line 171):

• If feature requires permission check: add specific case with permission check
• If no permission required: add to the list of cases that return true

Use templates from templates.md.

Step 6: Generate Boilerplate Code

Generate code snippets for manual implementation (don't auto-update these):

1. ViewControllerFactory method - Show code snippet
2. DependencyContainer registration - Show code snippet
3. Navigator extension (if deep linking) - Show code snippet

Use templates from templates.md.

Step 7: Validation

Before presenting results, verify:

• All files were updated successfully
• No syntax errors introduced
• Feature name is unique (not already declared)
• Permission code is unique (if provided)

Step 8: Present Results

Show comprehensive summary:

✅ Feature Declared: [FeatureName]

📋 Collected Details:
  - Name: [featureName]
  - Vietnamese: [vietnameseDesc]
  - English: [englishDesc]
  - Permission Code: [code or "None"]
  - Category: [category]
  - Icon: [iconName or "None"]
  - Deep Link: [path or "None"]

📁 Files Updated:
  ✅ Domain/Model/Others/Feature.swift (5 locations)
  ✅ Domain/Model/Others/FeatureInfo.swift (if has icon)
  ✅ PayooMerchant/Resources/Base.lproj/Localizable.strings (Vietnamese)
  ✅ PayooMerchant/Resources/en.lproj/Localizable.strings (English)
  ✅ PayooMerchant/Library/DeepLink/DeepLinkNavigator.swift (CRITICAL)
  ✅ PayooMerchant/Models/Feature+Ext.swift (CRITICAL)
  ✅ PayooMerchant/AppDelegateViewModel.swift (CRITICAL)
  [✅ Domain/Model/Setting/ScreenID.swift] (if deep linking)
  [✅ PayooMerchant/Library/DeepLink/Route.swift - 4 locations] (if deep linking)

📝 Manual Steps Required:

1. Add Icon Assets (if has icon):
   - Location: PayooMerchant/Resources/Assets.xcassets/
   - Create: [iconName].imageset/
   - Add images: 1x, 2x, 3x (24x24, 48x48, 72x72 pt)

2. Add ViewControllerFactory Method:
   [Show code snippet]

3. Register in DependencyContainer:
   [Show code snippet]

4. Create ViewController and ViewModel:
   - [FeatureName]ViewController.swift
   - [FeatureName]ViewModel.swift
   - Follow MVVM + RxSwift Input/Output pattern

[5. Add Navigator Extension (if deep linking):
   [Show code snippet]]

✅ Verification Checklist:
  - [ ] Build project successfully
  - [ ] Run SwiftLint (bundle exec fastlane lint)
  - [ ] Test without permission (should hide feature)
  - [ ] Test with permission (should show feature)
  - [ ] Verify Vietnamese and English text
  - [ ] Test icon displays correctly
  - [ ] Test deep link (if applicable)
  - [ ] Test navigation to feature

🔗 Next Steps:
  1. Add icon assets to Assets.xcassets
  2. Implement ViewController and ViewModel
  3. Add factory method to ViewControllerFactory
  4. Register ViewModel in DependencyContainer
  5. Test thoroughly before committing
