Kotcha
Well it has been a long time between posts but I promise it is for a good reason. I have been busy learning. Learning Kotlin. Kotlin is a replacement for Java and has gained massive popularity on the Android platform. It is compatible with Java down to the bytecode level meaning you can have a mixed project - some Java some Kotlin. Whilst this sounds like it would be a great way to slowly migrate a large project this comes with some gotchas.
Over the course of trying to migrate two projects as well as spending time at work migrating to Kotlin I collected a set of gotchas - or Kotchas - that presented to the SWmobile meet up group here in Bristol
The slides are a bit hard / impossible to see in the video but here they are instead.
