How to embed a UILabel inside a UIView in swift - ios

Question

I need to create a UIView programmaticaly in swift, that view should contain an image and a label. Also I need to embed that label and the imageview inside that created view so that as I animate the constraints of the view, the label and the image shold also reposition itseld relative to the view. This is my code co far -
func banner(viewController:UIViewController){
let width = UIScreen.main.bounds.width
let dynamicView=UIView(frame: CGRect(x:0,y: -70, width:width, height:70))
let label = UILabel(frame: CGRect(x:0,y: 35, width:width, height:20))
dynamicView.backgroundColor=UIColor.green
label.center = CGPoint(x: width/2, y: 35)
label.textAlignment = .center
label.text = "I'am a test label"
UIView.animate(withDuration: 1) {
dynamicView.frame = dynamicView.frame.offsetBy( dx: 0, dy: 70 )
viewController.view.addSubview(DynamicView)
viewController.view.addSubview(label)
}
UIView.animate(withDuration: 1, delay: 3, usingSpringWithDamping: 1, initialSpringVelocity: 4, options: .curveEaseIn, animations: {
dynamicView.frame = DynamicView.frame.offsetBy( dx: 0, dy: -70 )
}, completion: nil)
}
}
I could achieve that by changing x and y position of each views,labels etc separately. But that code would not be clean and consise.

From the question, it is seen that you are adding the label as subview to the viewController's view. Since you wish to embed the label to the Dynamic view try adding the label to Dynamic view like
UIView.animate(withDuration: 1) {
dynamicView.frame = dynamicView.frame.offsetBy( dx: 0, dy: 70 )
viewController.view.addSubview(DynamicView)
dynamicView.addSubview(label)
}
