Swift API Integration Generator Skill
Purpose
Generate complete API integration layers from specifications. This skill creates service classes, Codable models, error handling, authentication, and matching unit tests following iOS best practices.
Capabilities
- •Parse OpenAPI/JSON specifications to generate Swift code
- •Create service classes with async/await and Combine support
- •Generate Codable models matching API DTOs
- •Implement authentication with token refresh
- •Add offline support and caching strategies
- •Generate comprehensive unit tests with mocks
- •Create documentation comments
Usage
When implementing API integrations, I will:
- •Analyze the API specification (OpenAPI, Postman, or custom JSON)
- •Generate models that match the API response/request structure
- •Create service classes with proper error handling
- •Implement authentication including token management
- •Add caching and offline support where appropriate
- •Generate unit tests with mock responses
Common Tasks
Generate from OpenAPI
python
python service_generator.py --spec api-spec.yaml --output Services/
Generate models from JSON
python
python model_generator.py --json response.json --name UserResponse --output Models/API/
Generate complete integration
bash
./generate_api_integration.sh --api-name Orders --base-url https://api.example.com
