Have an error when I use Form. This happened on XCode for Beta 1 and Beta 2NavigationView{ Form{ Text(Hello World) }

Has anyone successfully used SwiftUI previews on a machine with a mechanical disk drive?Both the first and second betas of Xcode have been unable to generate previews on this installation.Results are any of a variety of errors, extraordinarily long compile times, inability to launch the simulator, a kernel panic or being logged out.An unmodified project created using the Xcode single-view template simply doesn't work.The experience is akin to using an ill-behaved Desk Accessory in System 7 :-(It's unclear whether the problem is with Xcode itself or the Catalina installation.Wondering if anyone has been through this and resolved the problem?

I am trying to get myself going with swiftUI. I was playing with the code below and trying to get the print() to work to see some variables during runtime in the preview window. Unfortunately it won't run once I add the print(), I get an Expected Declaration flag. Any info on using print() would be great as I have spent a few hours wondering around Google looking for answers with no luck so far.import SwiftUI struct ContentView : View { @State var username: String = let word1 = Username let word2 = Password print() var body: some View { VStack(alignment: .leading) { Text(Login) .font(.title) .multilineTextAlignment(.center) .lineLimit(nil) Text(Please) .font(.subheadline) HStack(alignment: .center, spacing: 10) { Text(Username: ) TextField($username, placeholder: Text(type something here...)) .textFieldStyle(.roundedBorder) } HStack(alignment: .center, spacing: 10) { Text(Password: ) TextField($username, placeholder: Text(type something here...)) .textFieldStyle(.roundedBorder) } }.padding(

Just getting started with SwiftUI. Exciting stuff.I understand that List would be one of the main building blocks that I can use in place of UI/NSTableView. One thing I haven’t seen yet: how to get and set the scroll position? Specifically, my list would consist of “read” and “unread” items. When the user first enters the list, everything is unread, so the list can start at the top. As new items scroll into view, they become “read”. When the user now leaves the list, and later returns, the list should scroll to the first “unread” item. So I am not so much interested in the pixel-level scroll offset, but rather, how do I scroll the viewport into the right location so that the user would see the desired info. The API could be something like “scroll the list such that model object X is visible in the middle” (with or without animation).The read/unread state is easily expressible as a model object property. I’m having trouble with how to bind it to the list scrolling in this new declarative world of ours

How do I draw roundedrectangle (or other shapes) in SwiftUI?I can't seem to find an example for it. Thanks in advance

Is there an equivalent for UIRefreshControl in SwiftUI?Thanks.

I'm working through the Handling User Input tutorial, which I am assuming many of you have done as well.If I preview LandmarkList immediately after Section 2, Step 3 with showFavoritesOnly set to true, I get a blank cell when showFavoritesOnly is set to true.After completing Section 3, Step 1 -- with the iteration through landmarkData being driven by the ForEach, this problem resolves itself -- the blank cell is no longer visible when showFavoritesOnly is set to true.Can someone please explain why this extra blank cell is showing up?

Hello,Does anybody know how to create a splitview in SwiftUI for the iPad?I mean a view like Settings, left the options and right the details.If I use HSplitView(), I got the error: 'HSplitView' is unavailable in iOS.VSplitView() got the same error.Kind Regards,Kitty
