I have the exact same problem. .disable() or .allowsHitTesting() have no effect if the view below is a hosted UIKit view (in my case its a hosted UICollectionView). Taps and gestures are still captured by the SwiftUI View above the collection view. The hack posted in the answer by @chase also does not work for me.

Annoyingly, same bug here on 2015 iMac 5k running Big Sur 11.1

Same problem here as shown in the screenshot of Darren. "iOS 17.0" is grayed out and clicking on the "Get" button does not work. I used xcodebuild -downloadAllPlatforms in Terminal, but this downloaded and installed only simulators, not the SDK (?).
