That sounds excellent.

I have not encountered anything like that, with my Swift (native iOS) apps, but am pretty close to it, with my backend PHP.

I suspect that it depends on the tech stack. So far, the Swift output closely resembles that of a very inexperienced, but smart, engineer; One that has read up on all the "tips and advanced tricks" you can do with Swift, but has never shipped anything substantial. I need to really keep a close eye on it.
