@caseylisscom This is a detour but I’d love to hear how you custom implemented the large title getting “sucked” into the navigation bar as you scroll. It looks quite seamless, and I’ve always had trouble getting anything fancy to happen with the navigation bar in SwiftUI. Are you observing the scroll offset and using it to set the opacity of the navigation bar title view, or something?
@ObjectiveJi Yeah, basically, reading scroll position of the main area, and then I have this in each view that uses my bespoke title:
@caseyliss Oh! It’s actually a toolbar item in the principal location! That approach never occurred to me, I was too locked into thinking of it as a navigation bar title and not a toolbar item. TIL!
