HI, I'm looking for an online training, book or a virtual school where you can learn the full cycle of software development. I want to cover subjects in a deeper level than a demo or a tutorial. I find many different topics on the internet, and there are not integrated or too small. I am using Xcode since 3 years and i still lack some of the basics like creating test functions, using instruments, code data, clout and many more. and i makes my development long and not as strong as i use to do before swift. my goal is to build apps that mostly capture data and store them, calculate statistics and present them after. also, is there a mentor / mentoree system ? any recommendations ? Thanks for your support !
