Hey, Im in the same boat, but I have been trying on and off for the past 3-4 years. Every time I restart, I am happy that I recall some of the basics, but I always have trouble piecing everything together to develop an actual app.
I find the Code With Chris YouTube channel to be easy to follow and has great tutorials and he is constantly updating and providing fresh content with Apple's updates.
All this being said, if anyone has any recommendations on piecing everything together... please let me know.
