class PDFCreator: NSObject {
let defaultOffset: CGFloat = 20
let tableDataHeaderTitles: [String]
let tableDataItems: [TableDataItem]

init(tableDataItems: [TableDataItem], tableDataHeaderTitles: [String]) {
    self.tableDataItems = tableDataItems
    self.tableDataHeaderTitles = tableDataHeaderTitles
    
}

func create() -> Data {

    let pageRect = CGRect(x: 0, y: 0, width: pageWidth, height: pageHeight)
    let renderer = UIGraphicsPDFRenderer(bounds: pageRect, format: UIGraphicsPDFRendererFormat())
    let numberOfElementsPerPage = calculateNumberOfElementsPerPage(with: pageRect)
    let tableDataChunked: [[TableDataItem]] = tableDataItems.chunkedElements(into: numberOfElementsPerPage)
    let data = renderer.pdfData { context in
        for tableDataChunk in tableDataChunked {
            context.beginPage()

        }
    }
    
    return data
}


func calculateNumberOfElementsPerPage(with pageRect: CGRect) -> Int {
    print("defaultOffset",defaultOffset)
    let rowHeight = (defaultOffset * 3)
    let number = Int((pageRect.height - rowHeight) / rowHeight)
    print("number",number)
    return number
}}

The header and table of the code I wrote works fine. but i can't change xy locations it won't let me MyPDFTable
