UIColor not working with RGBA values

Question

I am trying to change the text colour in a UITextField using the following code (RGBA value) however it just appears white, or clear, I'm not too sure as the background is white itself.

passwordTextField.textColor = UIColor(red: CGFloat(202.0), green: CGFloat(228.0), blue: CGFloat(230.0), alpha: CGFloat(100.0))  passwordTextField.returnKeyType = UIReturnKeyType.Done passwordTextField.placeholder = "Password" passwordTextField.backgroundColor = UIColor.clearColor() passwordTextField.borderStyle = UITextBorderStyle.RoundedRect passwordTextField.font = UIFont(name: "Avenir Next", size: 14) passwordTextField.textAlignment = NSTextAlignment.Center passwordTextField.secureTextEntry = true 

Answer 1

RGB values for UIColor are between 0 and 1 (see the documentation "specified as a value from 0.0 to 1.0")

You need to divide your numbers by 255:

passwordTextField.textColor = UIColor(red: CGFloat(202.0/255.0), green: CGFloat(228.0/255.0), blue: CGFloat(230.0/255.0), alpha: CGFloat(1.0)) 

Another thing, you don't need to create CGFloats:

passwordTextField.textColor = UIColor(red:202.0/255.0, green:228.0/255.0, blue:230.0/255.0, alpha:1.0) 

Answer 2

Using convenience init ( code like a pro )

Step 1

extension UIColor {     convenience init(r: CGFloat, g: CGFloat, b: CGFloat) {         self.init(red: r/255, green: g/255, blue: b/255, alpha: 1)     } } 

Usage

//let color = UIColor(red: 202/255, green: 228/255, blue: 230/255, alpha: 1) ☠️ let color = UIColor(r: 202, g: 228, b: 230) // 😍
