One workaround that seems to fix the problem for now is to put the following code in e.g. viewIsAppearing: var theView = self.view while theView != nil { theView?.backgroundColor = .clear theView = theView?.superview } Using this, the sheet is displayed with a transparent background on iOS 26.

We're also experiencing this exact crash. No problems on Xcode 16.3 with the 18.4 runtime.

We have the same issue in our project. Font styles (regular, bold, etc.) are completely broken when we compile our App against the iOS 17 SDK.

Same issue here. Only solution we found, is to set custom font programmatically.
