I'm experiencing the same thing with WkWebView (not in SwiftUI). Xcode 14.0 beta 6 (14A5294g)

Reviewing the Xcode 14 release notes (https://developer.apple.com/documentation/xcode-release-notes/xcode-14-release-notes) today, I came upon this unfortunate item: "Xcode 14 cannot be used with iOS 15.7 for development. (99847608) Workaround: Use Xcode 13.4.1 with iOS 15.7."

See this https://developer.apple.com/forums/thread/714388

Try changing 1.1 to 1.1.0 for "Version".
