iOS 14 has Changed (or broken?) SwiftUI GeometryReader

Question

As of today\'s release of iOS 14.0 my iOS code, which depends heavily on GeometryReader for layout, is no longer working well. I.e, layout has been kind of randomized.

Answer 1

Editing my previous answer as its now obviously bad advice

From https://developer.apple.com/documentation/xcode-release-notes/xcode-12-release-notes

Rebuilding against the iOS 14, macOS 11, watchOS 7, and tvOS 14 SDKs changes uses of GeometryReader to reliably top-leading align the views inside the GeometryReader. This was the previous behavior, except when it wasn’t possible to detect a single static view inside the GeometryReader. (59722992) (FB7597816)

Which says, to me at least, that the previous behaviour was buggy by their standards - despite it matching the conventions for other layout containers like VStack. And that this behaviour is the new normal.
