Juli Clover, MacRumors:

Apple today provided developers with the fourth betas of iOS 26 and iPadOS 26 for testing purposes, with the updates coming two weeks after Apple seeded the third betas.

I am still left with two bugs on iPad that I can’t get to the bottom of.

The first, above, is a sidebar that doesn’t react to light and dark mode changes, always leaving text looking black. (I’ve registered for trait changes to try and force it to white, but it doesn’t make a difference.)

The second issue is leading swipe actions where the content of the cell is offset by the size of the sidebar (but only when the sidebar is visible).
