What is Code Quality

  • Making Code that's easy to maintain
  • Low Cyclomatic Complexity
  • Making your code easily testable
  • Your code should read like sentences
  • Avoid fancy short code for more wordy code
  • Messy code is easier to fix then over-engineered code
  • While the integration may be complex, keep your code separated into simple parts 

Why is Code Quality Important

  • Saving Time = Saving Money
  • Easy to Maintain and Easy to Update
  • Shorter Onramp for New Developers
  • Code Rots over Time (Delegation Patters vs Subscriber/Publisher Model)
  • Addresses Tech Debt

When should you upgrade your code

  • When it makes sense
  • Use Interoperability (bridge headers, HostingControllers, ViewRepresentable, etc...) to slowly bridge the gap
  • Be careful leaving too much old code behind

Good Swift Code Quality

  • Use argument labels and parameter name correctly
  • Avoid ternary operators
  • Avoid switch statements with too much logic and cases
  • Use Generics judiciously
  • Extensions are great for separating Protocol implementation

Good Code Reviews and Pull Requests

  • Clear your mind
  • Use pull requests and templates
  • Add context and details to the pull requests
  • Use screen shots to show what the result is
  • Communicate clearly what is going on
  • Let them know what to look at and what is a work-in-progress

What Can Managers Do

  • Set a great example 
  • Provide enough time to the team for quality code
  • Have some background and experience with quality code
  • Be attentive and open to what your developers say
  • Allow time for unit testing
