“column”

Hello everyone. I'm having a problem using the table sort function in Swiftui. Here's an example to illustrate (data is provided by an API that returns fake data) : struct CompanyListResponse: Codable { let status: String let code: Int let total: Int let data: [CompanyData] } struct CompanyData: Codable, Identifiable { let id: Int let name: String let email: String } @Observable final class ViewModel { var companies : [CompanyData] = [] func fetch() async { guard let url = URL(string: https://fakerapi.it/api/v1/companies?_quantity=200) else { return } do { let (data, _) = try await URLSession.shared.data(from: url) let decoder = JSONDecoder() let response = try decoder.decode(CompanyListResponse.self, from: data) self.companies = response.data } catch { print(Error fetching data: (error)) } } } struct ContentView: View { @State private var viewModel = ViewModel() @State private var sortOrder : [KeyPathComparator] = [.init(.name, order: SortOrder.forward)] var body: some View { Table(of: CompanyData.self, sort

I am trying to render a list of entities that are split into sections (think CoreData NSFetchedResultsSectionInfo). This my solution, however it renders poorly. The ScrollView is far too long, scrolling is not fluid and may freeze. struct SectionsGridView: View { let results: Sections let columns = [ GridItem(.adaptive(minimum: .cellSize)) ] var body: some View { ScrollView { LazyVGrid(columns: columns, spacing: .gridSpacing, pinnedViews: .sectionHeaders) { ForEach(results) { section in Section(header: Text(section.title?.uppercased() ?? error)) { ForEach(section) { item in GridCell().environmentObject(item) } } } } } } } private extension CGFloat { static let gridSpacing = 8.0 static let cellSize = 100.0 } I believe this solution (or very similar) used to be in the documentation. I have tried several ways of doing this, either I get the scrolling issue or pinnedViews won't pin.

Hi there! can someone help me with this one: func resetMatrix() { matrix = Array(repeating: Array(repeating: 0, count: numberOfColumns), count: numberOfRows) let coordinates = [ (selectedRow1, selectedColumn1), (selectedRow2, selectedColumn2), (selectedRow3, selectedColumn3) ] for (row, column) in coordinates { matrix[row - 1][column - 1] += 1 } } i can't seem to make it work. i want it to work like this: If the chosen coordinate in Question 1 is (2,2), it will place the value 1 in the matrix coordinate (2,2). If the chosen coordinate in Question 2 is also (2,2), it will increment the value in the matrix coordinate (2,2) by 1, making it 2. Similarly, if the chosen coordinate in Question 3 is (2,2), it will increment the value in the matrix coordinate (2,2) by 1 again, making it 3. Thank you!

I'm fairly new to Swift programming so I might be overlooking something, but I'm puzzled why the following code doesn't properly insert a row in a DataFrame. The goal is to move a row at a given index to a new index. I would normally: Copy the row that I want to move Remove the row from the original dataset Insert the copy to the new position The CSV I'm using is from Wikipedia: Year,Make,Model,Description,Price 1997,Ford,E350,ac, abs, moon,3000.00 1999,Chevy,Venture Extended Edition,,4900.00 1999,Chevy,Venture Extended Edition, Very Large,,5000.00 1996,Jeep,Grand Cherokee,MUST SELL! air, moon roof, loaded,4799.00 My code (Swift playground): import Foundation import TabularData let fileUrl = Bundle.main.url(forResource: data, withExtension: csv) let options = CSVReadingOptions(hasHeaderRow: true, delimiter: ,) var dataFrame = try! DataFrame(contentsOfCSVFile: fileUrl!, options: options) print(Original data) print(dataFrame) let rowToMove: Int = 2 let row = dataFrame.rows[rowToMove] print(Row to move) print(ro

FB9108925 FB10408005 Since Apple Silicon we've seen a lot of WebDAV instability in macOS 11.x, 12.x and now 13.x that isn't found on x86 Macs. Some were fixed in earlier minor OS upgrades (e.g. webdavfs-387.100.1 that added a missing mutex init), but it's still highly unreliable. The purpose of this post is to put more focus on the bug, see if there is something else we can do to help solve this, as well as hear about potential workarounds from other people experiencing the same problems. I've got a reproducible case described below that triggers a deadlock in VFS every time, requiring a hard reboot to fully recover. Before reboot I've captured this stack trace showing the WebDAV/VFS/UBC/VM layers getting tangled up (macOS 13.2 Build 22D49 running on Macmini9,1): Thread 0x16358 1001 samples (1-1001) priority 46 (base 31) 1001 thread_start + 8 (libsystem_pthread.dylib + 7724) [0x18d2e0e2c] 1001 _pthread_start + 148 (libsystem_pthread.dylib + 28780) [0x18d2e606c] 1001 ???

So basically I can tell that the images are being saved by the system (it shows it on the debug terminal) however whenever I close, and then reopen the app the images firstly aren't there at all but also whenever I search the address name I saved them as... I have tried diagonsing the problem by changing UUID's, changing PNGs to JPGS - no matter what I do it does not show once the application has closed. I think it might have to do with how the image are .HEIF (apple's standard) but I don't have any concrete evidence to back this up. If anyone can help it would be greatly apperciated. import SwiftUI import MapKit import CoreLocation struct ContentView: View { @StateObject private var mapAPI = MapAPI() @State private var text = @State private var locationInfo: String = @State private var showLocationInfo = false @State private var imageUrls = [String]() // Array to store image URLs @State private var showImagePicker = false @State private var showCamera = false @State private var selectedImage: UIImage? @Sta

I have a view that shows a table and 4 buttons. Each button allows the user to step forward and backwards through the data. Buttons are enabled and disabled based on where you are in the data. If you are less than 200 values to the end of the data for example, the Page Down - 200 button is disabled. Everything works fine if the mouse is used to run the code associated with each button. But in this case I think the buttons never get focus. Focus I think remains with the sidebar content item that brought up the table view (am using a navigation split view). If I tab over to the page down 200 button and use the space bar to run its associated code I get the error AttributeGraph: cycle detected through attribute 864480. I think the problem lies with attempting to disable the button while it has focus but am not 100% sure. I have tried to change the focus prior to disabling the button but I get the same error. I think there is some fundamental that I am missing. Below is my table view along with the page down 200

Hi ! I am having a very strange problem. I display a list of elements, and I created a view that takes this element as a parameter in order to allow the user to modify it in another view. my var with a forEach : @Binding var liste : Liste my code : ScrollView { LazyVGrid(columns: [GridItem(.adaptive(minimum: 100))], spacing: 5) { ForEach(liste.cartes) { c in NavigationLink(destination: ModifierUneCarte(carte: c)) { VStack { Text(c.devant) .font(.system(size: 14)) Divider() Text(c.derriere) .font(.system(size: 14)) } } } } } and my ModifierUneCarte : struct ModifierUneCarte: View { [...] @Binding var carte: Carte [...] And I have this error on a lot of lines : Conflicting arguments to generic parameter 'Content' ('<>' vs. '<>' vs. '<>' vs. '<>') but it's because of : NavigationLink(destination: EditMap(map: c)) { because when I remove it everything works...
