Currently, in order to use the new features of UISplitViewController in iOS 14, it must be initialized using init(style:). However, as a result, the Split View can't be instantiated from a Storyboard, as its initialized with init(coder:) instead. Is there currently a workaround for this, or will it change with a future SDK release?

The WWDC Session "Discover WKWebView enhancements" talks about a new WKWebView.find method (around 19:40) for finding a string within a webpage. However, I can't find it in the Documentation - https://developer.apple.com/documentation/webkit/wkwebview?changes=latest_minor, and it doesn't appear in Xcode's autocomplete, even though I'm building against the iOS 14 SDK, and can use other new APIs (like pageZoom).

I just downloaded the Xcode 12 beta, and I'm running it on macOS Catalina. Whenever I open my project, I get a message at the top of the source editor stating that "An internal error occurred. Editing functionality may be limited". Swift source files don't have any autocomplete or syntax highlighting, but other files (such as a .h file) work just fine. This issue persists even when starting a new project. Has anyone else encountered this, and if so, is there a workaround to get it working again?
