How can I use UIColorFromRGB in Swift?

Question

In Objective-C, we use this code to set RGB color codes for views:

#define UIColorFromRGB(rgbValue)        
[UIColor colorWithRed:((float)((rgbValue & 0x         


        

Answer 1

In Swift3, if you are starting with a color you have already chosen, you can get the RGB value online (http://imagecolorpicker.com) and use those values defined as a UIColor. This solution implements them as a background:

    @IBAction func blueBackground(_ sender: Any) {
        let blueColor = UIColor(red: CGFloat(160/255), green: CGFloat(183.0/255), blue: CGFloat(227.0/255), alpha: 1)
        view.backgroundColor = blueColor

@Vadym mentioned this above in the comments and it is important to define the CGFloat with a single decimal point
