This is the Swifter Swift presentation I gave at the London Swift Meetup in Clapham today (15th September 2014). Apologies for the stock photos/standard template, I focussed on the content.
I also showed the optimisation levels as described in this blog post.
Things I Forgot To Mention
Use constants - declare with let unless avoidable, allows extra optimisation. Test before changing to mutable state within a function for performance reasons.
Currently the optimiser can do better within a particular file although this will be fixed at some point.
