Course Structure

• Lectures: Once a week, 1.5 hours each.
• Homework Assignments: 5 assignments spread over Weeks 1-12.
• Final Project: Week 11 brainstorming, Weeks 12-14 working; teams of 3.

Attendance Policy

• You are allowed 2 free absences before deductions are made.
• If for some reason you cannot make a lecture for a week, you may join the other section for full attendance. To do this, you must ask at least 48 hours on Ed before the section you'd like to join.
  • For everyone in the Thursday 202 section, this means you must ask before Tuesday that week since this is the one with the same content. (Attendance is required!)
  • You must let us know over (a private post in) Ed. If you ask over email, we will ask you to post on Ed instead.
• If you are unable to attend class due to a health-related reason or family emergency, please let us know on Ed.

Late Policy

• You may have a 2 day extension for any assignment, as long as you let us know 24 hours on Ed in advance.
  • As with attendance, this must be done over Ed.
• Any submissions made past the assignment deadline drops the grade down to a maximum of 50%, and any submissions made after a week is a 0%.
• The above policies do not apply to the final project - late submissions will not be accepted due to their proximity to presentations.
• If you are unable to submit an assignment due to a health-related reason or family emergency, please let us know on Ed.

AI Policy

• You may use ChatGPT or other generative AI tools, but we advise against relying on them.
  • AI-based tools are usually outdated on iOS development practices - oftentimes, ChatGPT will give you way more code (both in terms of quantity and complexity) than you actually need to implement.
• We suggest starting and writing up the code structure on your own, and then potentially using ChatGPT to fill in the blanks.
  • Relying on AI from the start may lead to UI and logic bugs that are difficult to debug later down the line.
• At the very least, make sure to understand every line you write.

Grading

• Attendance and Participation: 10%
• Homework Assignments: 60%
  • HW0: 20 points
  • HW1-4: 100 points each
• Final Project: 30%
