let storyboard = UIStoryboard(name: "Pickers", bundle: nil)
let myViewController = UIViewController()
myViewController.preferredContentSize = CGSize(width: 320, height: 200)
myViewController.modalPresentationStyle = .popover
let popOver = myViewController.popoverPresentationController
popOver?.delegate = self
self.present(myViewController, animated: true, completion: nil)
popOver?.permittedArrowDirections = .init(rawValue: 0)
popOver?.sourceView = self.view
let rect = CGRect(
origin: CGPoint(x: self.view.frame.width/2, y: self.view.frame.height/2),
size: CGSize(width: 1, height: 1)
)
popOver?.sourceRect = rect
}

could you please check this code this is working fine in iphones in my case.
let popoverContent = self.storyboard!.instantiateViewController(withIdentifier: "PopOverViewController")
let ktagForLabel = 100
let popOverWidth = UIScreen.main.bounds.width - 40
if let label = popoverContent.view.viewWithTag(ktagForLabel) as? UILabel {
let descriptionText = self.subcategoryDetailViewModel.displayServiceDescriptionForPopOver(forIndex: sender.tag/10)
label.text = descriptionText
var estimatedTextHeight = descriptionText.heightWithConstrainedWidth(width: popOverWidth, font: UIFont.systemFont(ofSize: 15)) + 16
let nav = UINavigationController(rootViewController: popoverContent)
nav.isNavigationBarHidden = true
nav.modalPresentationStyle = UIModalPresentationStyle.popover
let popover = nav.popoverPresentationController!
estimatedTextHeight = estimatedTextHeight > 150 ? 150: estimatedTextHeight
popoverContent.preferredContentSize = CGSize(width: popOverWidth, height: estimatedTextHeight)
popover.delegate = self
popover.permittedArrowDirections = .up
popover.sourceView = sender
popover.sourceRect = sender.bounds
self.present(nav, animated: true, completion: nil)
}
