🎉 Best Practices, Tips & Resources

📚 Lab Guide • ← Vision

Getting Better Suggestions

  1. Write Clear Comments: Use descriptive comments before functions to guide Copilot

    // Function to validate email format using regex, returns true if valid
func validateEmail(_ email: String) -> Bool {

  2. Use Descriptive Names: Well-named variables and functions help Copilot understand context

    // Good: Copilot understands what you need
let filteredLandmarksByCategory =

// Less clear
let filtered =

  3. Provide Examples: Show Copilot what you want with an example

    // Example: formatDate("2024-01-15") returns "Jan 15, 2024"
func formatDate(_ dateString: String) -> String {

Working with Agent Mode

  • Be Specific: Instead of "improve this code", say "add error handling and input validation"
  • Break Down Tasks: Large features work better as multiple smaller prompts
  • Review Changes: Always review multi-file changes before accepting
  • Iterate: If the result isn't perfect, provide feedback and ask for adjustments

Chat Effectively

  • Select Context: Select relevant code before asking questions
  • Use Slash Commands (if available):
    • /explain - Explain selected code
    • /fix - Fix issues in selected code
    • /tests - Generate unit tests
    • /doc - Generate documentation
  • Ask Follow-ups: Treat it like a conversation with a senior developer

Troubleshooting

🚀 Next Steps

Now that you've completed the workshop, try using Copilot in your own projects:

  1. Start Small: Use inline suggestions for routine coding tasks
  2. Ask Questions: Use chat to understand unfamiliar codebases
  3. Refactor Confidently: Use Agent Mode for large-scale changes
  4. Iterate: Don't expect perfection on the first try — refine your prompts
  5. Stay in Flow: Let Copilot handle boilerplate so you focus on architecture

Remember: Copilot is a tool to augment your skills, not replace them. Always review generated code for correctness, security, and adherence to your project's standards.
