alrt.setMessage(font: UIFont(name: "Poppins-medium", size: 20), color: UIColor.white)
let btn1 = UIAlertAction(title: "While using the app.", style: .default,handler: nil)
let btn2 = UIAlertAction(title: "Only this time.", style: .default,handler: nil)
let btn3 = UIAlertAction(title: "Deny", style: .default,handler: nil)
alrt.addAction(btn1)
alrt.addAction(btn2)
alrt.addAction(btn3)
alrt.view.tintColor = UIColor.blue
let subview = (alrt.view.subviews.first?.subviews.first?.subviews.first!)! as UIView
alrt.view.subviews.first?.subviews.first?.subviews.first?.backgroundColor = UIColor.black
let imageView = UIImageView(frame: CGRect(x: 180, y: 0, width: 35, height: 35))
imageView.image = Icon
alrt.view.addSubview(imageView)
fromView.present(alrt, animated: true, completion: nil)

as #Larme said, you can use a custom one ( a third party lib ).
Here is the solution of customize UIAlertController
class Alert: UIAlertController{
let offset: CGFloat = 20
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if let title = getLabel(for: view){
var f = title.frame
f.origin = CGPoint(x: f.origin.x, y: f.origin.y - offset)
title.frame = f
}
}
func getLabel(for v: UIView?) -> UILabel?{
guard let vue = v else{ return nil }
var result: UILabel?
for sub in vue.subviews{
sub.clipsToBounds = false
if sub.isKind(of: UILabel.self){
return sub as? UILabel
}
else {
result = getLabel(for: sub)
if result != nil{
return result
}
}
}
return result
}
}
use like this:
let alrt = Alert(title:nil, message: msg, preferredStyle:.actionSheet)
