Create new iOS system UIImages by tinting any source image

More than 1 year has passed since last update.

Convert an image asset of any color to appear like a Apple system icon, with these easy extensions. Use icons with no transparent backgrounds for best results!

First, add the familiar "Apple blue" color

extension UIColor {

    class func rgb(r: Int, g: Int, b: Int, alpha: CGFloat) -> UIColor{
        return UIColor(
            red: CGFloat(r) / 255.0, 
            green: CGFloat(g) / 255.0, 
            blue: CGFloat(b) / 255.0, 
            alpha: alpha)

    class func rgb(r: Int, g: Int, b: Int) -> UIColor{
        return self.rgb(r: r, g: g, b: b, alpha: 1.0)

    class var appleBlue: UIColor {
        get {
            return UIColor.rgb(r: 0, g: 122, b: 255)

Then use it with this handy tint extension

extension UIImage {

    func tint(with color: UIColor) -> UIImage
        guard let context = UIGraphicsGetCurrentContext() else { return self }
        context.scaleBy(x: 1.0, y: -1.0)
        context.translateBy(x: 0.0, y: -self.size.height)

        let rect = CGRect(x: 0, y: 0, width: self.size.width, height: self.size.height)
        context.clip(to: rect, mask: self.cgImage!)
        guard let newImage = UIGraphicsGetImageFromCurrentImageContext() else { return self }
        return newImage
