I've been around long enough to see this argument come and go under a lot of different names. This time it's AI. Maybe AI really does change the economics. But this post doesn't demonstrate it. Talk to me in a year. The side-by-side comparisons? Whoopty do. It's different code. Of course agents can produce two implementations that look the same today. That's not the hard part. The hard part is keeping them the same.…

Re: Shopify is moving from React Native back to Swift and Kotlin
#142If you put every company that needs/has an app on a spectrum, there is a line somewhere that roughly divides them into two groups: where Electron/React Native/etc. makes sense or not. It's just a normal engineering decision: solving problems given limited resources. Companies have different problems and different resources.

For an example that I actually have experience with, React very frequently gets criticized for being slow, heavy etc. React is not slow. I can make (have made) fast and snappy websites in react. React can render at more than 60fps if necessary, and if the code isn't shit. The fact that someone else has made a slow buggy mess with React does not prove that react is bad, it simply proves that the developers are bad. At this point, someone will typically interject with something along the lines of "but react makes it hard to make fast websites" and to that I simply say no it doesn't. I've seen what makes react apps slow, and it's generally just bad code. The developers who make shitty react apps would make equally shitty apps with any tool because they're the problem not the tool. They don't know how to build good software and literally no tool can help them because it's simply a matter of understanding programming and the sad fact is most developers suck at programming.
I graduated university with about 200 others and out of those people who have the same degree as I do, very few were even decent at programming. I know that because I was the guy who helped them complete their assignments and I was a TA in several different classes, and I'm telling you the overwhelming majority of students sucked at programming even after 2-3 years of studying it.
After graduating I've worked on many different web apps and other stuff, and I've seen an overwhelming trend of trash code and bad developers. The people who actually care about writing good software and have the mental facilities to do so are few and far between. And that's why most software sucks. A good developer can write good software using pretty much any of the popular tools. The tools are just different ways to do the same stuff. Sure there's some overhead with react etc but it's really not that significant, the significant part is all the trash code people put on top of it.

#143We did the same thing - had 90% of it overnight. Then spent a few days in the background tweaking for polish. Our app is smaller, and has about 15-20 screens. I started at about 12:30am by giving codex a goal and it inventoried every screen based on the react native code, then created android and iOS directories, used maestro (I had already set up this tooling for a previous personal app build a few weeks prior), and…

I think you contradicted yourself. If a tool provides better value for the time spent for a company, I don’t understand how you can call it objectively bad. You can say it’s objectively bad from a technical perspective, but clearly that’s only one part of the equation.
It's objectively bad because of how hot my phone is. It's subjectively bad because it's an embarrassment. Like you're seriously going to tell me something like Discord, worth 15 BILLION, cannot afford native apps? Spare me.

None of this matters anymore. We have LLMs. It's easy to build native everything now without much resource expenditure. Android will be Kotlin. iOS will be Swift. Desktop and server will be Rust. Web will be TypeScript / React for now, but maybe one day WASM. LLMs are the target now.

And the “makes sense or not” part can change based on a bunch of factors. It’s actually pretty common for a new company to start fully native (only iOS, few features, limited scope), then switch ro react native/electron (need to support more surfaces, features are being developed too quickly), then back to fully native (can afford individual dev teams for each platform).

Your assumptions are very outdated. App Store review times are typically < 24 hours and have been for the last couple of years. And KMP makes cross-platform a real thing now, rather than hacking a web view into a native shell, which was always the worst possible user experience.
Doesn't KMP assume your team is comfortable working in Kotlin?
KMP can be seen as a token optimization at this point. Business logic is shared and doesn't have to be rewritten in Swift.
