Swift Summit Conference report

This is the first Swift conference I have attended since starting Swift development 6 months ago. Below are some of my key takeaways from the conference:

  • Protocol-oriented programming and value semantics are the recommended paradigms to follow in Swift programming.
  • ReactiveCocoa
    • A library that, allegedly, provides a very logical way to deal with the event sequence ( synchronously and asynchronously)
    • This open source library brings the paradigm “Functional Reactive Programming” to ios. This paradigm is a new concept to me which I look to explore further.
  • Beyond the block based API: Building a simple Future
  • How to build a compelling Watch App
    • Introduction to what makes sense in a Watch app – A very simple use case
    • Basic features to build in a Watch app to make it compelling
      • Animations
      • Dictation
      • Device-to-device communication
  • Protocol MVVM
    • An example using UITableViewController with a custom tableview cell to provide a use-case of Protocol MVVM to View Controllers
    • Talk derived from the speaker’s blog posts here and here
  • Compile time guaranteed.
    • The talk started off with the importance of why we need to test our code.
    • This talk then focused on how we should approach Swift coding to ensure that most of the errors happen at compile time.
  • 55 Swift standard library protocols
    • The speaker classified the standard library protocols into 3 different categories and recommends us to identify similar scenarios in our coding:
      • Can do (end in Able)
        • Hashable, Equatable, Comparable, CustomPlaygroundQuickLookable
      • Is a (end in Type)
        • CollectionType, SequenceType, GeneratorType
      • Can be (end in Convertible)
        • FloatLiteralConvertible,CustomStringConvertible

The other talks dealt with the following:

  • Example of compiler time optimizations done by the Swift
  • Introduction to error handling, Swift 2.0 style (guard/defer, do-try-catch, throws)
  • Lyft’s high-level experience in re-writing their Obj C app completely in Swift.
  • Introduction on how to do Apple Pay
  • Introduction on starting tvOS coding

Once the videos and slides of the conference are out, I will share them

Overall it was a great experience to see what the most-discussed topics are in the Swift world and to interact with the great speakers and organizers of the conference.
