How to create custom UISegmentedControl?

Question

I want to create my custom UISegmentedControl like in the image below. There should be a gap between the buttons like in the screenshot. I have searched but did not get a complete solution.

Here is screenshot:

I tried this:

let items = ["Dialy", "Weekly", "Monthly"]    
lazy var segmentControl: UISegmentedControl = {  
    let control = UISegmentedControl(items: items)      
    control.selectedSegmentIndex = 0     
    control.layer.cornerRadius = 9      
    control.layer.borderWidth = 1      
    control.layer.masksToBounds = true      
    control.layer.borderColor = UIColor.white.cgColor  
    control.addTarget(self, action: #selector(handleSegmentControl(sender:)), for:.touchUpInside)    
    return control    
}()
```
