Coding Rules for Swift Apps

  • Keep classes and similar below 100 lines.
  • Keep methods below ten lines, preferably five.
  • Don't check state variables or type to determine behavior (make a new type).
  • Make data sources their own type.
  • View controllers should subscribe to no more than two delegate protocols.
  • Classes manage their own behavior.

These are guidelines only. Break any if your circumstance calls for it.
