Intermediate level swift - what kind of apps, besides games, make money?

Anyone know how to put my swift knowledge to best use?

I made my first iPhone app - it's called Simple Eat, basically a random food generator to test out my skills and put my first app on the iOS store. It took about a week to make and is free

now that that's done, what should my next project be? Looking to get some steady income

Added (1). @anon how do you know my level of swift based off an app? It isn't necessarily the case that the app represents my development capability. Also, how do you know how many hours each day I spent on it?

Added (2). for the record, I have a bachelor's degree in computer science lmao, probably more than you

First: Realize that you're still a little kiddy programmer, "intermediate" my ***… That app would take me only an hour or two at most to make.

Second: Stop thinking you're going to make any money with your lack of skillz.

What you do is just keep making apps until one make's a lot of money or the collective sum of them makes you steady income

My first app made nothing, but about 2 years after I started and 5 apps I was making about 1500-2000 per months, although most of it was from a single app with in app purchases. That's where the money is, in my opinion
