User Profile

Hello, I'am an Unity game developer. Iam using custom Binary files to save game progress data (encoded strings, int, bool etc.). Now before I build my project/game to Xcode and upload it to the Appstore, I want the user to be able to save their progress to the iCloud so they can play on multiple devices and restore/override their game data if needed. However I can't find online a step for step guide on how to achieve this. The data that I would need to store for 1 user would probably not be more then 100 int/bool/float etc. I want to know what "Cloud system" I should use in my situation, and how to synchronize my binary files to iCloud. Help would very much be appreciated!
