Usage Examples

Prompt Template

Analyze the following Swift codebase from [COMPANY] in the [INDUSTRY] sector and identify areas that can be migrated to Swift Concurrency. Provide a step-by-step migration plan, including code examples for each refactored component. Ensure compatibility with [XCODE_VERSION] and integration with our CI/CD pipeline using [CI_TOOL].

Example Output

# Swift Concurrency Migration Plan for [COMPANY] App

## Current Codebase Analysis
- **Legacy Patterns Identified**: Completion handlers, delegate patterns, and GCD usage in [DATA] modules.
- **Concurrency-Ready Components**: Networking layer and data processing tasks.

## Migration Strategy
1. **Networking Layer**: Replace `URLSession` completion handlers with `async/await` and `Task`. Example:
   ```swift
   func fetchData() async throws -> Data {
       let (data, _) = try await URLSession.shared.data(from: url)
       return data
   }
   ```
2. **Data Processing**: Convert serial queues to `async` functions with `Task` groups for parallel processing.
3. **UI Updates**: Use `MainActor` for UI updates to ensure thread safety.

## CI/CD Integration
- Add a migration test suite to the pipeline to verify concurrency compliance.
- Monitor performance metrics post-migration for regression.
