With the correct corner radius changing in iOS 26, I wondered if there is a way to get properly rounded corners inside containers like sheets without hard-coding a constant value. Here's the results of some experiments I did, example code below. The new in Beta 4 ConcentricRectangle seems nice. Notable here is that it doesn't pick up the larger corner radii from the device corners: If you want all the corners rounded, the isUniform parameter of ConcentricRectangle seems helpful. It doesn't apply the corners in a View in the middle though, not sure if this is an oversight or if this has some purpose: ContainerRelativeShape looks ... interesting ... as of Beta 4, with the larger bottom corners rounded according to the device corners, but the actual bottom corners not fitting the device corners.
