adjusting navigationTitle based on dynamic type size

Is this an iOS app?

I wouldn't expect navigation titles to get much larger with Dynamic Type on iOS, since the user can press and hold to access the Large Content Viewer. This WWDC session is a few years old but talks about relevant and helpful APIs regarding Large Content Viewer: https://developer.apple.com/videos/play/wwdc2019/261/

Looking at a few first party apps like Messages or Settings, the navigation title only grows for a few text sizes past 100% but then caps out. This is the behavior I'd recommend for your UI.

Otherwise please feel free to share UI screenshots if it helps the discussion.

Thank you, I will review that session. Yes, this is on iOS. In my app, the SwiftUI navigationTitle was getting truncated at larger sizes.

My solve was to shorten it, and add in a subtitle at largest sizes to still convey meaning.

private func navigationTitleAbridged(for title: String) -> String {
    if dynamicTypeSize >= .accessibility2 { return fullSqueeze(title) }
    if dynamicTypeSize >= .xxxLarge { return halfSqueeze(title) }
    return title
}

Your solution is really clever (and looks good too) but yeah I understand the "chasing your tail" aspect.

I have a feeling we can do better here, if you wouldn't mind submitting feedback for this as well.

Thanks for your guidance and feedback on this, I really appreciate it! The tail chasing ensued around trying to smooth out edge cases (i.e. a truncation on iPhone SE), but fix one break another. So I left it alone at generally better than where it started.
