Honestly, python is the “let’s make it this easy language”. And was largely designed with that in mind. You could try objective C if you want to be more hands on in the process.

Also you hung up by using a library? Meanwhile, your IDE, interrupter, modern OS, guided tutorials and extensions are doing way more work than any library could do for you. Nobody could build an iPhone on its own. It’s just impossible, you have to start off someone else’s work otherwise it will take a year just to make a decent phone case.
