Objective-C

Greetings everyone. I ran a design studio for 8 years in which we designed mobile and web apps. I also lead development teams when our client asked us to carry out the development of the projects. I always had an interest in learning to code to help me understand what is going on on the dev side and also build small apps as a hobby. I tried several times to get on a learning path, but challenges always put me down, so I quit after a couple of weeks. I tried JavaScript, Python, PHP, and Objective-C.

Now I am retrying to teach myself Swift and especially SwiftUI for more than a month, and It's been going well so far. I want to build my own small apps, and I'm not focused on getting hired as a developer. I want to ask if it's the right language to start learning to program or should I learn something else first as a foundation. I'm currently taking a 100 days of code challenge and reading the Swift 5.3 PDF if I want to get more information on a specific topic. It feels like none of the stuff is sticking, but I'm not sure if it's the way it goes or my approach is wrong.

I would appreciate any kind of guidance. Thanks
