can anyone teach me apple develper?
The best is to start using good tutorials, like Apple Books "Intro to App development with Swift".
And ask questions on the forum when there is something you don't understand.
You will see, it is fun but also requires efforts on your side. Try by yourself and ask question only when you are really in trouble. Trying, testing, failing, trying again and making it is the best way to learn.
Good luck.
