Do I have to learn and use Apple's language if I want to make "App Store" apps for iDevices and Macs?

Let's say I have made something in HTML, CSS and JavaScript, and I currently have it running in NW.js, the Chromium-based "webview" which runs on Windows, macOS and Linux.

Now I want to actually make money, and not just have people theoretically find it and jump through hoops to make it run.

That means it has to go into the Apple "App Store", and be usable on iPhones. And I have to buy the cheapest possible Mac Mini as well as a developer fee to be able to submit it to the App Store. (I already have registered an "Apple ID" account.)

It appears as if Apple heavily suggests that you use Xcode and Objective C or Swift. I obviously would like to skip that part. In fact, if it's a requirement, I might as well forget about this whole thing.

Is it a requirement? Or am I allowed to use what I already know, meaning "web technologies"? And if I'm allowed to, does it come with some kind of punishment/downside? Will my app be labeled as "lesser", and/or will it run poorly on iPhones and in practice force me to learn and use Apple's language/environment after all?

Solution 1:

No, iOS apps can be written in just about any language, as long as you can get it to work on the iPhone. You might have to wrap your code in Objective-C or Swift at the very end, but you could build the vast majority of your app in any language without any sort of penalty or punishment.
