I decided to put the source code for my first app onto GitHub.
Back in the heady days of 2012 and 2013, I decided that after 8 years of doing front-end development that I wanted to become an iOS developer.
I ended up having to teach myself Objective-C, C (for Core Image manipulation), Cocoa, Blocks, GCD, Storyboards, Mobile Design, Code Signing and the list goes on and on and on.
There's a lot of rough edges on the app, it's pretty clear that this is someone's first public release.
The application did pay off though, I managed to make enough money off of it that it paid for a few years of iOS development access and it gave me enough confidence with iOS/Cocoa to ultimately get a job doing iOS development full time.
Plus I created some really great images:
