• Modern navigation UI out-of-the-box via a Flyout control
• Navigate via routes

• Unified design by default via Visual and Material Components

Now Released in Xamarin.Forms 4.0

Feed ItemList behind Navigation on iOS

Tested on iOS Device, when navigating to FeedPage the list appears behind the navigation bar (see Attachment)

Roadmap for Shell

Hi David, is there a roadmap outlined for Shell (at least until the version release candidate) ?

Thanks

What's the oldest iPhone & iOS for Gastropods?

This is not an issue but an observation and a couple of questions.

Gastropods runs great on 12.3.1 (6s) and newer phones and iOS versions.

Gastropods starts on 9.3.5 (4s) but then it quits.

I have set the Minimum System version to 9.3 and the architecture to ARMv7 + ARMv7s + ARM64.

What's the blocking element for 9.3.5 (4s) so I can remove it?
A package? A class?

What's the oldest iPhone & iOS for Gastropods (and/or for the Xamarin package versions upon which Gastropods depends)?

Thanks.
