Change the label of UIPickerView

I am trying to change the font of UIPickerView.

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView!) -> UIView {
    let label = UILabel()

    label.font = UIFont(name:"SynchroLetPlain", size:20)
    //label.font = UIFont.systemFont(ofSize: 17) //Even I use systemFont, it doesn't show nothing
    return label
}

It is ok for compile though, no text is shown.

Where is defferent? I have checked SynchroLetPlain is included in project.

Try this:

label.font = UIFont(name:"Synchro LET Plain", size:20)

I guess the problem is related to actual name of a font. I mean that iOS search font by it actual name, not the file name of the font.

Update:

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView?) -> UIView {
    var label: UILabel
    if let view = view as? UILabel {
        label = view
    } else {
        label = UILabel()
        label.font = UIFont(name:"SynchroLetPlain", size:20)
    }
    label.text = "text" // your text
    return label
}

Try this one

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
        var label: UILabel
        if let view = view as? UILabel {
            label = view
        } else {
            label = UILabel()
        }
        label.font = UIFont(name:"SynchroLetPlain", size:20)
        // where data is an Array of String
        label.text = "" // set data here
        return label

    }

Additionally: 

func printFonts()
    {
        for fontFamilyName in UIFont.familyNames {
            print("-- \(fontFamilyName) --", terminator: "")
            for fontName in UIFont.fontNames(forFamilyName: fontFamilyName ) {
                print(fontName)
            }
            print(" ", terminator: "")
        }
    }

Call this function, which gives you the exact name of the font which you have to use to set the font.
