I'm working on a document reader for long form articles and I love what WebKit gives me for quickly delivering good looking content. But I'm hearing that accessibility support is stronger if I go with UIKit or SwiftUI. Accessibility support is meant to be a headline feature in my app so it's the deciding factor on which technology I should use (webview versus UIKit/SwiftUI).
Given Accessibility Reader now provides system-wide reflow and spoken reading, is there now a durable reason a document reader developer should still invest in native UIKit/SwiftUI rendering rather than well-structured HTML in a webview? Where specifically does the system stop helping webview content? What I've heard is that webviews are disadvantaged on custom rotors, focus, and Dynamic Type fidelity. Is this accurate or has it changed this year? Bottom line, I'm wondering if WebKit is a compromise for a11y if I want not baseline accessibility, but truly leading unsurpassed accessibility.
