Most social media apps liek FB/Insta/Snapchat have complex camera and photo handling code as well as async messaging code. that’s not true at all. Given how apps like Netflix and YouTube are so nicely synced between mobile, web and STBs I'd still imagine all the logic and persistence is server-side. Once you have that setup you can then add a different platform "web/iOS". Our approach forces you to keep UI code just focused on UI, while keeping all logic somewhere else, where it can isolated and as a benefit much more easily unit tested. It's usually pretty easy to tell Cordova apps from native apps. As someone who has had to maintain apps across web, iOS and Android, the answer to that is most definitely no.

Kotlin - loved by native devs We are doing something similar on my project except using the J2OBJC compiler. Authentication and identity management comes to mind immediately. Of course, part of these Swift problems can be that the team choose to pursuit performance and low-overhead above everything else (which complicated the implementation quite a bit). - Data model operations on local copy of data: For some use cases you can't just send everything to the server all the time, instead you want a local representation which is periodically synced with the server, - Logging / monitoring: Expose a single logging / monitoring API which can be shared across platforms.

If you're moving most of logic to the server, why have an app at all? As has been pointed out, Kotlin is not really controlled by Google the way that Flutter is. Additionally, it includes a number of language and library improveme Just maybe with more tooling...
