About The Assembler
Learn Assembly programming and binary operations by painting little pixel art pieces. The app teaches different operations in each of the ten chapters. For each of the chapters you program an image with a limited set of commands. Eight rows of 8-Bit Registers turn into your canvas. Use Assembly to manipulate the values in every register, thus creating an 8x8 painting. 'The Assembler' was made as a small and fun introduction to Assembly, Programming and the Binary system that powers it all. The first version of this app was made for the Swift Student Challenge 2022 and won! I hope that you enjoy this project as much as I have.
