> No one should really be writing UI code by modifying a file by hand because UIs are often complex and deep, so the file structure used to store the UI data doesn't need to be human-readable. I strongly disagree. SwiftUI is fucking amazing. https://developer.apple.com/tutorials/swiftui/ https://developer.apple.com/tutorials/swiftui/ Even with your other comment about "until you hit a moderate level of complexity." People are already creating some complex things with it. In fact, they can be more complex than what you can achieve with traditional frameworks when you consider the time it takes; what takes me a day in UIKit etc. takes me a minute in SwiftUI, so I can quickly move on to the next bit. With declarative UI code I could literally have a usable app in the same time it takes me to struggle with getting separate visual designers + logic editors to agree over a single moderately complex component. Though, it is several layers of abstraction over what really happens behind the scenes, so I guess a part of your point stands.
