For Swift:

Swift 3:

extension UIView {

    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }

    @IBInspectable var borderWidth: CGFloat {
        get {
            return layer.borderWidth
        }
        set {
            layer.borderWidth = newValue
        }
    }

    @IBInspectable var borderColor: UIColor? {
        get {
            return UIColor(cgColor: layer.borderColor!)
        }
        set {
            layer.borderColor = newValue?.cgColor
        }
    }
}

Swift 2.2:

extension UIView {

    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }

    @IBInspectable var borderWidth: CGFloat {
        get {
            return layer.borderWidth
        }
        set {
            layer.borderWidth = newValue
        }
    }

    @IBInspectable var borderColor: UIColor? {
        get {
            return UIColor(CGColor: layer.borderColor!)
        }
        set {
            layer.borderColor = newValue?.CGColor
        }
    }
}

I got Answer Change layer.borderColor to
layer.borderColorFromUIColor

enter image description here

and add the code in .m file

#import <QuartzCore/QuartzCore.h>
@implementation CALayer (Additions)

- (void)setBorderColorFromUIColor:(UIColor *)color
{
    self.borderColor = color.CGColor;
}

@end

Tick properties in Attribute Inspector

Attribute Inspector

The explanation, perhaps being lost in some of the other answers here:

The reason that this property is not being set is that layer.borderColor needs a value with type CGColor.

But only UIColor types can be set via Interface Builder’s User Defined Runtime Attributes!

So, you must set a UIColor to a proxy property via Interface Builder, then intercept that call to set the equivalent CGColor to the layer.borderColor property.

This can be accomplished by creating a Category on CALayer, setting the Key Path to a unique new “property” (borderColorFromUIColor), and in the category overriding the corresponding setter (setBorderColorFromUIColor:).

In case of Swift, function doesn’t work. You’ll need a computed property to achieve the desired result:

extension CALayer {
    var borderColorFromUIColor: UIColor {
        get {
            return UIColor(CGColor: self.borderColor!)
        } set {
            self.borderColor = newValue.CGColor
        }
    }
}

This works for me.

Identity inspector (UIButton in this case

CALayer extension:

extension CALayer {
var borderWidthIB: NSNumber {
    get {
        return NSNumber(value: Float(borderWidth))
    }
    set {
        borderWidth = CGFloat(newValue.floatValue)
    }
}
var borderColorIB: UIColor? {
    get {
        return borderColor != nil ? UIColor(cgColor: borderColor!) : nil
    }
    set {
        borderColor = newValue?.cgColor
    }
}
var cornerRadiusIB: NSNumber {
    get {
        return NSNumber(value: Float(cornerRadius))
    }
    set {
        cornerRadius = CGFloat(newValue.floatValue)
    }
}
