column

I am working with data in Swift using the TabularData framework. I load data from a CSV file into a DataFrame, then copy the data into a second DataFrame, and finally remove a row from the second DataFrame. The problem arises when I try to remove a row from the second DataFrame, at which point I receive an EXC_BAD_ACCESS error. However, if I modify the timings column (the final column) before removing the row (even to an identical value), the code runs without errors. Interestingly, this issue only occurs when a row in the column of the CSV file contains more than 15 characters. This is the code I'm using: func loadCSV() { let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first! let url = documentsDirectory.appendingPathComponent(example.csv) var dataframe: DataFrame do { dataframe = try .init( contentsOfCSVFile: url, columns: [user, filename, syllable count, timings], types: [user: .string, filename: .string, syllable count: .i

I have a dataset with 3 columns item_id, user_id, rating. I created a coreML MLRecommender model from this dataset. I want to use this model to get the top 10 predictions for a new user (not in the original dataset) but who has rated a subset of the items in the dataset. I don't see any API in the Apple docs to do this. Both the recommendations APIs only seem to accept an existing user-id and get recommendations for that user. The WWDC tutorial talks about a prediction API to achieve this. But I dont see this in the Apple API documentation and code below from WWDC tutorial cannot be used since it does not give details on how to create the HikingRouteRecommenderInput class it passes into the prediction API. let hikes : [String : Double] = [Granite Peak : 5, Wildflower Meadows : 4] let input = HikingRouteRecommenderInput(items: hikes, k: 5) // Get results as sequence of recommended items let results = try model.prediction(input: input) Any pointers on how to get predictions for new user would be greatl

The issue I am encountering is, I need to be able to create a view in SwiftUI that looks like a sentence of text but has blanks where the user can enter their own text. I also need a way to be able to capture the entered text from the binding, but not sure how to do multiple bindings in a loop. Ive tried a few options and the closest I have got is using LazyGrid, but it doesn't look like a normal sentence due to spacing? Any help appreciated. struct MultiText: View { @State var text = There was once a {-} that only had {-} in it. How did they get in? {-} @State var answerText: String = XXXXXXX let rows = [ GridItem(.adaptive(minimum: 80)) ] var body: some View { GeometryReader { geo in HStack { LazyVGrid(columns: rows, alignment: .leading, spacing: 0) { ForEach(text.components(separatedBy: ), id: .self) { component in if component == {-} { TextField(, text: $answerText ) } else { Text(component) } } }.frame(width: geo.size.width * 0.80) Image(systemName: flag).frame(width: 30, height: 30) }.frame(wi

Hello, I am turning to this forum because I suspect I am doing it wrong when it comes to implementing VoiceOver accessibility in my collection view. I suspect this because the system has resisted everything I have tried to do, fought it tooth and nail, and I can't see any way to get this to work. The Collection View I have a collection view that displays a large dataset. It uses a custom collection view layout to create a spreadsheet-like view. It has hundreds of rows, and each row can have hundreds of items. The items in each row do not conform to specific column widths. Their width is defined by the data they display, and for the purposes of this discussion, can be considered to be arbitrary. To the left of the table is a column of sticky headers whose position remains fixed in relation to the content. On top of the table is a row of headers, whose position also remains fixed. The Problem The default accessibility behavior that Apple has baked into UICollectionView is completely impractica

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

Is there a way to print a simple report of the tests? We want a list of tests, with a report of ‘pass’ or ‘fail’ for each one. We need this for the V&V process for our app. We found what we want in the ‘Report Navigator’ (the option on the far right in the left hand column on Xcode) by clicking on ‘Test’. However, this isn’t printable. Below ‘Test’ is ‘Build’, ‘Coverage’, and ‘Log’, which can be exported, but all of them show more information that we wanted. (Photo for reference) Is there a way to print out that page when you click on ‘Test’? What am I missing here?

I'm creating a horizontal scroll view through the collection view. I used flowlayout for layout, and I set the scroll direction to horizontal. I found a bug in this situation. If the width of the item is different, line spacing is not applied, but item spacing is applied. Since it is a horizontal scroll, line spacing should be applied in the direction of the column, but item spacing is applied. Does anyone know anything about this? // // ViewController.swift // minimumLineSpacingTest // // Created by Hoonki chae on 2023/07/12. // import UIKit class TestCell: UICollectionViewCell { } class ViewController: UIViewController { let collectionView = UICollectionView(frame: .zero, collectionViewLayout: UICollectionViewFlowLayout()) override func viewDidLoad() { super.viewDidLoad() self.view.backgroundColor = .white self.collectionView.frame = .init(origin: .init(x: 0, y: 100), size: .init(width: self.view.frame.width, height: 50)) self.view.addSubview(self.collectionView) self.collectionView.backgroundColor

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!

So, I am trying to create an app that is like a survey app. I am new to coding by the way (less than a month) I have this long-ass code that I am trying to work. Well, it is working except for one more part of the code. I've been trying to make it work for days now and I cannot seem to figure it out. I uploaded it in a google drive link above. This is what it is: If you try to run this code in Xcode, you can see a thing like this: The app works like this, users select the pickers beside the Criteria and Relative Risk. The scores will show as: Score: 2,4 (just a sample score) criteria = row relative risk = column what I want to happen is that this score will immediately translate as a coordinate in the risk matrix below. There are 21 sets of pickers for this part of the app. The coordinates can have more than 1 value. so if there are 3 scores that have the same coordinate, such coordinate in the matrix sho
