Build Simulator crash

Could you edit the code properly and format with Code formatter. In the present presentation it is just impossible to read. What are commented out lines ? What is the real code ? There seems to miss closing brackets… Where do you use relativeRiskPickerIndex31 ? Do you repeat code with relativeRiskPickerIndex1 to relativeRiskPickerIndex31 ? What are the values of those state var (they should always be between 0 and 4). Are they ? And please show where exactly the error occurs.

The code is very long so i hope this edit is sufficient to read. Where do you use relativeRiskPickerIndex31? - there are 31 "questions" in this part of the app,. each app has 2 sets of answers for users to choose from. #1 Slope Angle (they choose answer from picker one) and picker two in the relativeRiskPickerIndex.. basically there are from 1 until 31 risk picker indexes using this:

let relativeRiskChoices = ["Select", "Negligible", "Minor", "Moderate", "Significant", "Major"] let relativeRiskScores = ["-","A", "B", "C", "D", "E"] //the code above this line is from another swift file that just gets called to the file to the code below.

The state var values are all zero.

There is no error message inside the code lines but when I run the simulator and try to run and "pick" answers from the "questions" and answers inside the simulator, it Freezes and stops working. so i have to force quit it again to try to run it again.

however, if i do not use the pickers and just directly try to export pdf, it works.

The last time I tried this popped up on the debug area:

2023-07-03 22:28:42.363228+0900 LRAT[1382:14173] [Query] Error for queryMetaDataSync: 2 Swift/ContiguousArrayBuffer.swift:600: Fatal error: Index out of range 2023-07-03 22:32:08.544395+0900 LRAT[1382:12856] Swift/ContiguousArrayBuffer.swift:600: Fatal error: Index out of range (lldb)

I hope i shortened this code properly:

import SwiftUI import UIKit import PDFKit struct NaturalSlopeFormView: View { @Environment(.presentationMode) var presentationMode

//this part has 30 more state var of different names @State private var slopeAnglePickerIndex = 0

//this part has 1-31 @State private var relativeRiskPickerIndex1 = 0

var body: some View { NavigationView { Form { //this part has 7 groups with at most 5 sections each Group { Section(header: Text("Slope Angle").font(.title3).bold() ) { Picker("Criteria", selection: $slopeAnglePickerIndex, content: { ForEach(0..<QuestionData().slopeAngleChoices.count, id: .self) { index in Text(QuestionData().slopeAngleChoices[index]) } }) .pickerStyle(MenuPickerStyle()) Picker("Relative Risk", selection: $relativeRiskPickerIndex1, content: { ForEach(0..<QuestionData().relativeRiskChoices.count, id: .self) { index in Text(QuestionData().relativeRiskChoices[index]) } }) .pickerStyle(MenuPickerStyle())

                    Text("Score: \(QuestionData().slopeAngleScores[slopeAnglePickerIndex]), \(QuestionData().relativeRiskScores[relativeRiskPickerIndex1])")
                }

} .navigationBarItems(leading: HStack{ . . . } //this is for a button to export to PDF trailing: Button(action: exportToPDF){ . . . }

let pdf = PDFDocument() let page = PDFPage() pdf.insert(page, at: 0)

        // Define the column widths
        let columnWidths: [CGFloat] = [400, 100, 100]

        // Define the row height and padding
        let rowHeight: CGFloat = 15
        let padding: CGFloat = 5

        // Define the starting position for drawing
        var currentPosition = CGPoint(x: 20, y: 170)


        // Define the data for the table
        let relativeRiskOptions = ["A", "B", "C", "D", "E"]
       
        // Define the data for the table
        let tableData: [(String, Int, String)] = [
            ("Slope Angle", slopeAnglePickerIndex, relativeRiskOptions[relativeRiskPickerIndex1]),
            ("Slope Height", slopeHeightPickerIndex, relativeRiskOptions[relativeRiskPickerIndex2]),
            ("Slope Aspect", slopeAspectPickerIndex, relativeRiskOptions[relativeRiskPickerIndex3]),
            ("Slope Elevation", slopeElevationPickerIndex, relativeRiskOptions[relativeRiskPickerIndex4]),
              //this part goes until relativeRiskPickerIndex31
            

for (index, rowData) in tableData.enumerated() { let column1Text = NSAttributedString(string: "(rowData.0)", attributes: textAttributes) let column2Text = NSAttributedString(string: "(rowData.1)", attributes: textAttributes) let column3Text = NSAttributedString(string: "(rowData.2)", attributes: textAttributes)

            let column1X = currentPosition.x
            let column2X = currentPosition.x + columnWidths[0]
            let column3X = currentPosition.x + columnWidths[0] + columnWidths[1]
            
            let column1Rect = CGRect(x: column1X, y: currentPosition.y, width: columnWidths[0], height: rowHeight)
            let column2Rect = CGRect(x: column2X, y: currentPosition.y + (rowHeight - column2Text.size().height) / 2, width: columnWidths[1], height: rowHeight)
            let column3Rect = CGRect(x: column3X, y: currentPosition.y + (rowHeight - column3Text.size().height) / 2, width: columnWidths[2], height: rowHeight)
            
            column1Text.draw(in: column1Rect)
            column2Text.draw(in: column2Rect)
            column3Text.draw(in: column3Rect)
            
            currentPosition.y += rowHeight + padding
       return data

} }

Thank you!

Hi, I was able to make it work. I decided to start from scratch.

instead of doing this:

        let tableData: [(String, Int, String)] = [
            ("Slope Angle", slopeAnglePickerIndex, relativeRiskOptions[relativeRiskPickerIndex1]),
            ("Slope Height", slopeHeightPickerIndex, relativeRiskOptions[relativeRiskPickerIndex2])

i did this instead:

        let tableData: [(String, String, String)] = [
            ("Slope Angle", QuestionData().slopeAngleChoices[slopeAnglePickerIndex], QuestionData().relativeRiskChoices[relativeRiskPickerIndex1]),
            ("Slope Height", QuestionData().slopeHeightChoices[slopeHeightPickerIndex], QuestionData().relativeRiskChoices[relativeRiskPickerIndex2]),
