    return NSAttributedString(string: "Your Text", attributes: [NSForegroundColorAttributeName:UIColor.blue])

How do I change the font size in a UIPickerView in Swift?

Try this for Swift 3.x:

Fill your Font name, Color, Size & Data Array with appropriate values.

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
    var pickerLabel: UILabel? = (view as? UILabel)
    if pickerLabel == nil {
        pickerLabel = UILabel()
        pickerLabel?.font = UIFont(name: "<Your Font Name>", size: <Font Size>)
        pickerLabel?.textAlignment = .center
    }
    pickerLabel?.text = <Data Array>[row]
    pickerLabel?.textColor = UIColor.blue

    return pickerLabel!
}

EDIT:

For Multiple components, you can do something like this:

if component == 0 {
     var label: UILabel? = (view as? UILabel)
     label.text = <Your Arr>[row]
     return label
}else {
     return anotherLabel
}

Output:

How to change UIPickerView font size

NSAttributedString cannot be used to change font for UIPickerView.

You can change font by overriding pickerView(pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView?) -> UIView

How do I change the color of the text in a UIPickerView under iOS 7?

There is a function in the delegate method that is more elegant:

Objective-C:

- (NSAttributedString *)pickerView:(UIPickerView *)pickerView attributedTitleForRow:(NSInteger)row forComponent:(NSInteger)component
{
    NSString *title = @"sample title";
    NSAttributedString *attString = 
        [[NSAttributedString alloc] initWithString:title attributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]}];

    return attString;
}

If you want to change the selection bar colors as well, I found that I had to add 2 separate UIViews to the view containing the UIPickerView, spaced 35 pts apart for a picker height of 180.

Swift 3:

func pickerView(_ pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {

    let string = "myString"
    return NSAttributedString(string: string, attributes: [NSForegroundColorAttributeName:UIColor.white])
}

Swift 4:

func pickerView(_ pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {

    let string = "myString"
    return NSAttributedString(string: string, attributes: [NSAttributedStringKey.foregroundColor: UIColor.white])
}

Swift 4.2:

func pickerView(_ pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {

    let string = "myString"
    return NSAttributedString(string: string, attributes: [NSAttributedString.Key.foregroundColor: UIColor.white])
}

Remember when you use the method: You don't need to implement titleForRowInComponent() as it is never called when using attributedTitleForRow().
