They are not imaginary problems. And Apple's DX isn't "incredibly poor"; coding SwiftUI views with Canvas and the #Preview macro is a dream compared to farting around with Eclipse or one of it derivatives.
This isn't even going into what an utterly horrific editor it is that is plagued with bugs and is missing basic IDE features like a functioning autocomplete, refactoring etc. Mind you, at one point I was celebrating because they finally added highlighting your cursor line in an update after the extensions I used to add that broke. That's how bad Xcode was circa 2015 when simple text editors had those features baked in. If you're comparing Xcode to Eclipse and ranting about JS, then feels like you kept up with how engineering has evolved for Android and JS in maybe 5-10 years. In contrast, it feels like Xcode only adds incrementally miniscule changes and every time I look at it, they seem to not have improved it much at all
All this isn't even getting into what an awful experience simply updating the damn thing is. Why does it have to download 20GB every couple of months and why does it fail so often?
I'm sorry I'm so aggressive but nothing has made my hairs more gray than trying to work with Xcode. It is appalling that it's basically the only way you can develop apps for the Apple ecosystem
