column

Greetings, I'm just learning Swift language by Playgrounds and some Udemy educations. I have a problem with Coding 2 - Connect and Solve episode. I supposed to build 3 - 2 - 3 blocks to three spots on 2nd column BUT blocks are acting like ghosting, it appears like for 0.5 seconds and disappear again. Then only change that I made is updating MacOS system with the lastest patch. Open to any ideas about the issue. Tnank you!

I have a LazyVGrid, every item with is favorite button. and use combine to debounce user input($isFavoriteI), when isFavoriteO changed, then modify the items. it works fine, but when i scroll the list, log will print: X, isFavorite changed as false/true), what cause isFavoriteO changed and why? because of item reusing in list? how to avoid it? index 7, isFavorite changed as true index 7, isFavorite changed as true index 7, isFavorite changed as true index 7, isFavorite changed as true index 7, isFavorite changed as true index 7, isFavorite changed as true index 7, isFavorite changed as true index 7, isFavorite changed as true import SwiftUI import Combine struct Item { var index: Int var favorite: Bool } var items = [ Item(index: 0, favorite: true), Item(index: 1, favorite: false), Item(index: 2, favorite: true), Item(index: 3, favorite: false), Item(index: 4, favorite: true), Item(index: 5, favorite: false), Item(index: 6, favorite: true), Item(index: 7, favorite: false), // Item(index: 8, favorite: true), /

I have a custom Instrument with a os-signpost-interval-schema that captures a state string. I would like the final plot value to be : , but I don't know how to get the duration into the string. My working schema is the following, which just stores the state itself in the column: state-interval State Interval ... ... state ?state state State string ?state I would like to change the expression in the column to (str-cat ?state : ?duration), but that fails with: Variable '?duration' must appear in a pattern element to be used in a later expression. I don't see any way to compute this later in the graph, lane, or plot. I've also tried explicitly creating a , but that doesn't seem to change anything. The rest of the pieces include the table: state-table state-interval And the lane, which I would like to display as : rather than just the duration: State state-table state

I'm trying to reproduce in a way the finder column view, but I'm facing an issue. A scroll conflict occurs when I put a ScrollView or a List inside another ScrollView. The horizontal scroll is lagging when the cursor is over the nested ScrollView. Here is my simplified code: struct SplitView: View { var body: some View { ScrollView(.horizontal, showsIndicators: false){ HSplitView{ ScrollView(showsIndicators: false) { VStack(alignment: .leading) { ForEach(0..<100) { Text(Row ($0)) } }.frame(minWidth: 200, alignment: .leading) } ScrollView { VStack(alignment: .leading) { ForEach(0..<100) { Text(Row ($0)) } }.frame(minWidth: 200, alignment: .leading) } ScrollView { VStack(alignment: .leading) { ForEach(0..<100) { Text(Row ($0)) } }.frame(minWidth: 200, alignment: .leading) } } } } } I have the same issue with nested List. Do you have any idea how I can prevent that? Or any workaround?

Hello, I have a problem when I launch the application I have this error displayed in the log of the swift: Error Domain=NSCocoaErrorDomain Code=3840 JSON text did not have any content around line 2, column 0.

I have a macOS tableview I have a textfield as a column along with an IBAction code to capture the data from this field. I wanted to add continuous spell check for this column . So, I decided to change the column from a TextField to a ScrollView to take advantage of the continuous spell check. Using Xcode 14 I changed the Cell to a custom Cell. The custom cell has a scrollview object as the object because I want to take advantage of the built in continuous spell checking instead of using a textfield. All is well with this implementation until I tried to add a IBAction code for when I enter text in the scrollview/textView field. There does not seem to be a way to capture the text? Am I trying to do something that can't be done or is there a way to add continuous spell check to a textField?

I have a triple UISplitViewController. A UINavigationController is in the secondary column. When the selection changes in the supplementary column I call -setViewControllers:animated: and pass the navigation controller the new vc. I noticed sometimes the navigation view controller isn't updating and this logs out: setViewControllers:animated: called on while an existing transition or presentation is occurring; the navigation stack will not be updated. So this happens when the Split View controller itself is presenting another view controller modally (say a view controller with a UIActivityIndicatorView in it to show loading progress). But there is no transition/presentation occurring on the UINavigationController contained in the secondary view controller column itself. The presentation occurring on the UISplitViewController is completely separate and unrelated to the UINavigationController's navigation stack that's in the secondary column and therefore I should not be prev

I went back to square one since the NavigationLink isActive is deprecated, this is when I found out about NavigationSplitView which removes the hassle of creating a 2 column app. However, I can never figure out why the toggle button does not show. I copied this sample code (already tried 2 tutorials, copy pasted them but still no toggle button) Anyone know why? import SwiftUI enum DemoScreen: String, Codable { case first, second, third var title: String { rawValue.capitalized } } struct ContentView: View { @State private var selection: DemoScreen? = .first var body: some View { NavigationSplitView { sidebarContent } detail: { detailContent } } } extension ContentView { var sidebarContent: some View { List { link(to: .first) link(to: .second) link(to: .third) } } func link(to page: DemoScreen) -> some View { NavigationLink(value: page) { Text(page.title) } } } extension ContentView { @ViewBuilder var detailContent: some View { if let selection = selection { detailContent(for: selection) .buttonStyl
