Recently, we’ve developed our first open source Swift app, with a few folks involved, and most of them new to Swift. Outlining our own Swift style guide so that we don’t get lost in our own work was a must and we wanted to share it. Slides by Radek Szeja, iOS Dev at @netguru. More about the guide: https://netguru.co/blog/swift-style-guide-open-source
