Swift Pair Programming – Day 1

Just finished pair programming with Nick. He’s in San Francisco. And I’m in Hawaii. We’re using ScreenHero to pair and it’s fantastic. There was a bit of a lag in screensharing because my internet connection was pretty bad. Next time I’ll be pairing from the library or from Hi Capacity. An hour goes by really quickly. Maybe we need to meet for longer?

Prior to meeting I made a list of the topics that I understand the least:

  • Closures
  • Coalescing operators
  • Optional binding
  • Force unwrapping
  • Guard statements
  • Optional chaining
  • veratic parameters
  • inout parameters
  • Nested function that returns a function
  • Currying

Questions that came up this session

How to we indicate a multi type array?

Lessons learned

  • Playground will not show up the play button if its a playground inside of the xcode project.
  • edit all in scope.
  • can’t do ++ in swift
  • Figure out how to do a next item in swift that is safe
  • Use inout in your parameter list to mutate parameter. Be sure to call method with & on parameter to indicate inout status
