I'm working through various coding tutorials and have encountered the same warning numerous times. First, I must say that the symbolic breakpoint message is most unhelpful as I am developing in SwiftUI, not UIKit and have no idea where to place that breakpoint. Second, I did some experiments and found that one place the warning was coming from using the Button initializer with titleKey and systemImage parameters. A Button without systemImage did not cause the warning. I found that if instead I used the Button initializer with action and label parameters and added an Image using systemName for the label, there was no warning.

I am logged in with my Apple account. When I click on the POST button, I get this screen. I can enter a title, but nothing else works. I've created posts in the past. I am able to post this reply.

I figured it out. Xcode only shows revisions where the file was changed. So for example if the file was added in revision 10 and not changed until revision 13, those are the only two revisions that show up in the choices.

I wrote a simple test import Testing func target(value: Int) -> Int { value + 1 } struct ParameterizedTestTests { @Test(arguments: zip([1,2,3,4,5],[2,3,4,5,5])) func test1(x: Int, r: Int) async throws { #expect(target(value: x) == r) } } Note that the last test case should fail. I've run it numerous times, including shutting down Xcode and restarting and the test works, reporting the failure for the last test case. I went back into my original code and recreated problem test (I had rewritten the test to not use parameters). It was still acting up, but then I noticed in a previous parameterized test that the test was expecting UInt16 parameters, but the parameters given were Int (i.e. no type specified, which Swift defaults to Int). When I changed them to UInt16, it cleared things up. However, unlike a normal function call which complains if the type of the arguments don't match the type of the parameters, parameterized tests don't report a mismatch.

I'm seeing the same issue with Swift Playgrounds 4.6.2. It works with Swift Playgrounds 4.5.1.

Thanks for the reply. The issue was my understanding of how relationships work in SwiftData. I thought I was deleting the relationship. Here's my corrected deleteFavorites method. private func deleteFavorites(indexes: IndexSet) { for index in indexes { let friend = movie.favoritedBy[index] friend.favoriteMovie = nil } do { try context.save() } catch { fatalError("Could not create ModelContainer: \(error)") } } I had to add the context.save to get the view to update when no friends favorited a movie.

Thanks, The first step (drag window around) doesn't work for me in Full Screen mode. I'm still using Sonoma (14.7). Has that changed is Sequoia? I have to exit Full Screen mode, then the rest works. Mark

Thanks. One thing additional. I usually run in full screen mode. If you open a second project, I find you have to exit full screen mode to have access windows from both projects at the same time. Then you can tile on window to the left and one to the right.

I found one way, but it's cumbersome. I split the editor window, delete the file that's displayed on the right (it's the same as the one on the left), then drag the reference file's icon from the Finder to the right side editor. Is there a better way? I would hope that there is an Open option under the File menu, but that wants to open the previous project as a second project

Claude31, Thanks for the reply. It works. I figured it had something to do with calendars and timezones, but I couldn't find a simple example of how to put it all together. I'll keep your function handy. I live in the US Eastern Time Zone, so when I put in a date in GMT, it ended up the previous day, which makes sense. I changed the timezone to EST and then the date was correct. I'm used to Python which has both naive and aware (of time zone) date time values. Apparently, Swift's Date object is aware. Does Swift have a naive date time concept?

How to delete a post (I added the information to the original post)

One of the programmers in the local BuckeyeCocoa group turned me on to this resource in the Mac App Store. It's not free. A Companion for SwiftUI

The error happened again today on my old 2014 MBA which is limited to Big Sur. It happened after the upgrade to 11.6. This time, whenever I try to start the app, I get a dump.

Okay, this makes no sense, or I am obviously missing something in my understanding of SwiftUI. If I declare my Settings scene as: Settings { FCCDatabaseSettings(fccData: fccData) } Where FCCDatabaseSettings is a view and fccData is an @StateObject, the map does not drag smoothly. If, OTOH, I declare it as: Settings { SettingsWrapper(fccData: fccData) } Where SettingsWrapper is a view that simply calls FCCDatabaseSettings struct SettingsWrapper: View { @ObservedObject var fccData: FCCData var body: some View { FCCDatabaseSettings(fccData: fccData) } } The map drags smoothly. What is going on?
