How to merge two UIImages?

by

Hope this may help you,

var bottomImage = UIImage(named: "bottom.png")
var topImage = UIImage(named: "top.png")

var size = CGSize(width: 300, height: 300)
UIGraphicsBeginImageContext(size)

let areaSize = CGRect(x: 0, y: 0, width: size.width, height: size.height)
bottomImage!.draw(in: areaSize)

topImage!.draw(in: areaSize, blendMode: .normal, alpha: 0.8)

var newImage:UIImage = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()

All the Best 🙂
