How to set the custom border color of UIView programmatically?

I am trying to set the custom border color of UIView programmatically in Swift.

If you Use Swift 2.0+

self.yourView.layer.borderWidth = 1
self.yourView.layer.borderColor = UIColor(red:222/255, green:225/255, blue:227/255, alpha: 1).cgColor

In Swift 4 you can set the border color and width to UIControls using below code.

let yourColor : UIColor = UIColor( red: 0.7, green: 0.3, blue:0.1, alpha: 1.0 )
yourControl.layer.masksToBounds = true
yourControl.layer.borderColor = yourColor.CGColor
yourControl.layer.borderWidth = 1.0

< Swift 4, You can set UIView's border width and border color using the below code.

yourView.layer.borderWidth = 1

yourView.layer.borderColor = UIColor.red.cgColor

Use @IBDesignable and @IBInspectable to do the same.

They are re-useable, easily modifiable from the Interface Builder and the changes are reflected immediately in the Storyboard

Conform the objects in the storyboard to the particular class

Code Snippet:

@IBDesignable
class CustomView: UIView{

@IBInspectable var borderWidth: CGFloat = 0.0{
    
    didSet{
        
        self.layer.borderWidth = borderWidth
    }
}


@IBInspectable var borderColor: UIColor = UIColor.clear {
    
    didSet {
        
        self.layer.borderColor = borderColor.cgColor
    }
}

override func prepareForInterfaceBuilder() {
    
    super.prepareForInterfaceBuilder()
}

}

Allows easy modification from Interface Builder:

You can write an extension to use it with all the UIViews eg. UIButton, UILabel, UIImageView etc. You can customise my following method as per your requirement, but I think it will work well for you.

extension UIView{
    
    func setBorder(radius:CGFloat, color:UIColor = UIColor.clearColor()) -> UIView{
        var roundView:UIView = self
        roundView.layer.cornerRadius = CGFloat(radius)
        roundView.layer.borderWidth = 1
        roundView.layer.borderColor = color.CGColor
        roundView.clipsToBounds = true
        return roundView
    }
}

Usage:

btnLogin.setBorder(7, color: UIColor.lightGrayColor())
imgViewUserPick.setBorder(10)

Swift 5.2, UIView+Extension

extension UIView {
    public func addViewBorder(borderColor:CGColor,borderWith:CGFloat,borderCornerRadius:CGFloat){
        self.layer.borderWidth = borderWith
        self.layer.borderColor = borderColor
        self.layer.cornerRadius = borderCornerRadius
        
    }
}

You used this extension;

yourView.addViewBorder(borderColor: #colorLiteral(red: 0.6, green: 0.6, blue: 0.6, alpha: 1), borderWith: 1.0, borderCornerRadius: 20)

swift 3

func borderColor(){

    self.viewMenuItems.layer.cornerRadius = 13
    self.viewMenuItems.layer.borderWidth = 1
    self.viewMenuItems.layer.borderColor = UIColor.white.cgColor
}

We can create method for it. Simply use it.

public func createBorderForView(color: UIColor, radius: CGFloat, width: CGFloat = 0.7) {
    self.layer.borderWidth = width
    self.layer.cornerRadius = radius
    self.layer.shouldRasterize = false
    self.layer.rasterizationScale = 2
    self.clipsToBounds = true
    self.layer.masksToBounds = true
    let cgColor: CGColor = color.cgColor
    self.layer.borderColor = cgColor
}

Swift 3.0

       groundTrump.layer.borderColor = UIColor.red.cgColor

Write the code in your viewDidLoad()

self.view.layer.borderColor = anyColor().CGColor

And you can set Color with RGB

func anyColor() -> UIColor {
    return UIColor(red: 0.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 1.0)
}

swift 3.0

self.uiTextView.layer.borderWidth = 0.5
    self.txtItemShortDes.layer.borderColor = UIColor(red:205.0/255.0, green:205.0/255.0, blue:205.0/255.0, alpha: 1.0).cgColor

Swift 5*

I, always use view extension to make view corners round, set border color and width and it has been the most convenient way for me. just copy and paste this code and controlle these properties in attribute inspector.

extension UIView {
    @IBInspectable
    var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
        }
    }
    
    @IBInspectable
    var borderWidth: CGFloat {
        get {
            return layer.borderWidth
        }
        set {
            layer.borderWidth = newValue
        }
    }
    
    @IBInspectable
    var borderColor: UIColor? {
        get {
            if let color = layer.borderColor {
                return UIColor(cgColor: color)
            }
            return nil
        }
        set {
            if let color = newValue {
                layer.borderColor = color.cgColor
            } else {
                layer.borderColor = nil
            }
        }
    }
}
