Apple today took a shot at React Native and other cross-platform frameworks. I have thoughts. First, the quote in question, from their keynote (around the 40 minute mark): "Some other frameworks promise the ability to write code once for Android and iOS. And that may sound good, but by the time you've written custom code to adapt each platform's conventions, connected to hardware with platform-specific APIs, implemented accessibility, and then filled in functionality gaps by adding additional logic and relying on a host of plugins, you've likely written a lot more code than you'd planned on. And you are still left with an app that could be slower, look out of place, and can't directly take advantage of features like Live Activities and widgets. Apple's native frameworks are uncompromisingly focused on helping you build the best apps."
