Changed drawTableHeaderTitles method of https://github.com/alekseypotapov-dev/PDFCreatorExample

drawTableHeaderTitles.swift

func drawTableHeaderTitles(titles: [String], drawContext: CGContext, pageRect: CGRect) {
    // prepare title attributes
    let textFont = UIFont.systemFont(ofSize: 16.0, weight: .medium)
    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.alignment = .left
    paragraphStyle.lineBreakMode = .byWordWrapping
    let titleAttributes = [
        NSAttributedString.Key.paragraphStyle: paragraphStyle,
        NSAttributedString.Key.font: textFont
    ]

    // draw titles
    let tabWidth = (pageRect.width - defaultOffset * 2) / CGFloat(3)
    for titleIndex in 0..<titles.count {
        let attributedTitle = NSAttributedString(string: titles[titleIndex].capitalized, attributes: titleAttributes)
        let tabX = CGFloat(titleIndex) * tabWidth
        let textRect = CGPoint(x: tabX + defaultOffset, y: defaultOffset)
        attributedTitle.draw(at: textRect)
    }
}
