When I recognize that I loose interest in coding, I try to get in touch with other developers (for example in local meetup groups) to get new inspiration and motivation. It always helps me to get new ideas for (side) projects and motivates me to code.

I really like the simplicity of the Swift syntax. If you write "swifty" code, it almost reads like a poem in comparison to other languages, but is still extremely powerful. I was able to learn basic iOS Development with Swift in just a few month from no programming experience at all and it also allowed me to learn a lot of other languages based on my experience with Swift. Moreover I like that it was made open source and everybody can contribute to make Swift a even better language!
