Is there anyway to write data into array

[MatinC]

I trying to add each row automatically by running for-loop but it keep telling me index out of range there

` let itemList = objectNo
let fileManager = FileManager.default

    let documentDirectory = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
    csvFile = documentDirectory.appendingPathComponent("\(fileName!).csv")
    let path = csvFile
    
    let stream = OutputStream(url: csvFile!, append: false)
    let csv = try! [CSVWriter(stream: stream!)]
    try! csv[0].write(row: ["name", "x", "y", "width", "height"])
    
    for no in 0..<itemList.count - 1 {
        try! csv[no].write(row: [String(describing: objects.dataName[no]), String(describing: objects.dataX[no]), String(describing: objects.dataY[no]), String(describing: objects.boundingX[no]), String(describing: objects.boundingY[no])])
    }
    csv[itemList.count].stream.close()`

I'm assuming the issue is with the following line

csv[itemList.count].stream.close()

I'm not sure if the number of items in itemList equals the number of items in csv, but if this is true, then this would be the reason your code is crashing.
