I recommend that you watch WWDC 2022 Session 102 Platforms State of the Union, and specifically Josh’s section starting at 3:43.
From the transcript (with my emphasis):
Josh Shaffer: A great developer platform provides tight integration between programming language, frameworks and tools. When all three fully complement one another, we can ensure that common things are easy, and even uncommon things are possible.
Now, getting that right shortens the path to building a great app, and it benefits everyone. Customers get a consistent experience, like scrolling that always feels perfect. And you're able to focus your time and effort on what makes your app unique. But designs evolve, hardware advances, and what was once cutting edge becomes the expected baseline. The Objective-C language, AppKit & UIKit frameworks, and Interface Builder have empowered generations of developers. These technologies were built for each other, and will continue to serve us well for a long time to come, but over time new abstractions become necessary. For a while now, you've seen us hard at work defining the next generation of integrated language, frameworks, and tools: Swift, SwiftUI, and Xcode Previews.
Tight integration in a development platform like this requires that all three pieces be designed and evolved together, both driving and driven by one another. Swift result builders were inspired by SwiftUI's compositional structure. SwiftUI's declarative views were enabled by Swift value types. And Xcode Previews was specifically designed for, and enabled by, both. Now, the result is the best development platform that we have ever built. And this year, Swift, SwiftUI, and Xcode all have fantastic updates that take this vision further, and make it even easier for you to build great apps for all of our platforms. And it all starts with Swift. Now Ben from the Swift team is gonna tell you all about what's next.
Is the "long time to come" quote what you're referring to?
