I'm somewhat of a Flask pro but have struggled to find a good entry on how to use it as a backend for a native iOS app (for someone who completely missed the Swift train). I guess it starts with migrating to Fastapi?

Speaking of backend development, recently I gave Jooby[1] a try after discovering it was one of the world's top performer in Tech Empower's web framework benchmark[2].

Surprisingly enough, it's terribly easy to put together a REST API with Jooby. I was expecting a lot of arcane tricks to set things up, but it's one of the less.verbose frameworks out there.

I wonder why it's adoption rate is so low.

Not using Flask, but I've been using Django as backend for various iOS apps over the years. My recipe is just a REST API library + Django OAuth2 Provider. I imagine if I were to use Flask, I'll do the same thing: implementing the REST API and gate it using OAuth2. Plenty of library in iOS side that make hooking up with OAuth2 relatively easy.

Why fastapi, though ? What's missing in Flask if you just want to learn iOS programming ?

What is flask missing? FastAPI has swagger and open api stuff but it’s not like it’s required or necessary most of the time. I use my basic flask server as the most dead simple rest API backend for my iOS apps without any issues

As others have said: What has one to do with the other? As a Flask pro you probably know that you can create great APIs with it. And iOS apps can consume them.
