How to access extension of UIColor in Swift?

Question

I am very new to swift and trying to create an extension of UIColor class as

extension UIColor{

    func getCustomBlueColor() -> UIColor {
        retur         


        

Answer 1

Swift 3, Swift 4, Swift 5:

extension UIColor {
   static let myBlue = UIColor(red:0.043, green:0.576 ,blue:0.588, alpha:1.00) 
}

Use:

btnShare.setTitleColor(.myBlue, for: .normal)

Or

self.view.backgroundColor = .myBlue

If you use Color Set in *.xcassets (iOS11+). For example, you have a color with the name «appBlue». Then:

extension UIColor {

private static func getColorForName(_ colorName: String) -> UIColor {
    UIColor(named: colorName) ?? UIColor.red
}

static var appBlue: UIColor {
    self.getColorForName("appBlue")
}
}

Use:

self.view.backgroundColor = .appBlue
