Set the Gradient color in iOS swift

Solution:

The below code is used to set the gradient color to the particular view

first declare the colors

    let topColorsList: [String] = ["#f12711"]

    let bottomColorsList: [String] = ["#f5af19"]

        let gradientLayer:CAGradientLayer = CAGradientLayer()

        gradientLayer.frame.size = cell.moreView.frame.size

        

        gradientLayer.colors = [hexStringToUIColor(hex: topColorsList[indexPath.row]).cgColor,hexStringToUIColor(hex: bottomColorsList[indexPath.row]).cgColor]

        //Use diffrent colors

        cell.moreView.layer.addSublayer(gradientLayer)

The above code needs the below function for get the color from hexstring

 func hexStringToUIColor (hex:String) -> UIColor {

        var cString:String = hex.trimmingCharacters(in: .whitespacesAndNewlines).uppercased()

        

        if (cString.hasPrefix("#")) {

            cString.remove(at: cString.startIndex)

        }

        

        if ((cString.characters.count) != 6) {

            return UIColor.gray

        }

        

        var rgbValue:UInt32 = 0

        Scanner(string: cString).scanHexInt32(&rgbValue)

        

        return UIColor(

            red: CGFloat((rgbValue & 0xFF0000) >> 16) / 255.0,

            green: CGFloat((rgbValue & 0x00FF00) >> 8) / 255.0,

            blue: CGFloat(rgbValue & 0x0000FF) / 255.0,

            alpha: CGFloat(1.0)

        )

    }
