I take a backseat to nobody (or very few, at least) when trying to get Corona to fix bugs and improve the performance of components that should by now work across iOS and Android. Scrollview, webview, etc. are still not as useful as they should be at this late date: you can’t set the scroll speed for scrollview – this is different from friction – and webview doesn’t let you deny location requests.
That said, I think it’s unrealistic to try to get Corona to support iOS-specific stuff like Healthkit, Storekit, thumbprint, etc. If you want to access those APIs, start using Xcode and learn Swift. Or Xamarin if you like. Or Corona Enterprise. But until Android has similar features that show up on a lot of devices, Corona staff likely won’t (and probably shouldn’t) spend their time trying to match platform-specific features.
(If Microsoft were smart, they’d buy Corona Labs outright, let Walter buy a private island in the Caribbean and a jet to go with it, and try to make Corona the platform of choice for most mobile development. They could build out standard cross-platform libraries that implemented things like search boxes, which ksan is bravely trying to do right now, and create a nice GUI builder. Build a nice way to handle different device sizes gracefully, implement the best of Material Design and iOS 8, and offer lots of developer assistance. Then developers that switch to Corona would magically find their apps work – surprise! – on Windows Phone too. It might not actually work, but it’s better than their current strategy. Unfortunately Microsoft does not have a history of being smart about these things.)
