I think the killer feature of macs with Apple Silicon is that the iPad versions of Slack and Discord would "just work" and people wouldn't have to deal with Electron crap anymore.
I’ll believe the story that these will be any good when Catalyst apps will start behaving like native apps. If developers can’t bother making a native experience with frameworks that are meant to do this, I don’t think they will with an even simpler paradigm.
My canary in the coal mine: Apple’s own SF Symbols.
No. But a native iOS version will be even less (aka not at all) optimised for macOS than a catalyst app. My point is that devs using catalyst don’t respect any of the macOS idiosyncrasies so why would they when they write iOS apps?
An Electron app would still be better than a iOS version optimised for a big thumb.
Discord is made out of React native I think. The performance is incredible most of the times. Sometimes it goes crazy and uses 100% CPU for a long time as if there's a while loop somewhere.
And with Apple Silicon, Im not sure that the restriction right now is architecture. Swift supports both x86 and ARM right? The problem is that the interactions are different in the desktop OS and simply recompiling or running it on desktop would not be a great experience.
Apple Silicon macs can run iOS/iPadOS binaries natively, no recompilation and no Catalyst needed. I think the experience of iPad apps will be just fine.
