Update (23rd October 2014) - Now with video link HERE.

Swift optimisation presentation refined and developed further.

Please contact me if you want the source version and please let me know if you make use of it or find it useful.

Description of the demo from a previous event. Note that for Xcode 6.1 you will need to use the 0x, 1x, 2x and fullSpeedXC61 branches instead of the 0, 1, 2 and fullSpeed branches respectively. Likewise master currently has an Xcode 6.1 version although I will probably merge that to the real master shortly.

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.
