pkhud.swift

var activeTextField: UITextField?

@IBAction func logIn(_ sender: Any) {
    // ...
    HUD.flash(.labeledError(title: "blabla", subtitle: "blablalba"), 
              onView: activeTextField?.inputAccessoryView, 
              delay: 1.0)
    // ...
}

func textFieldDidBeginEditing(_ textField: UITextField) {
    activeTextField = textField // if keyboard is shown, show HUD.flash under inputAccessoryView

func textFieldDidEndEditing(_ textField: UITextField) {

var activeTextField: UITextField?

@IBAction func logIn(_ sender: Any) {
    // ...
    let customView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 300))
    customView.backgroundColor = .red
    textfield?.inputAccessoryView = customView
    HUD.flash(.labeledError(title: "blabla", subtitle: "blablalba"), 
              onView: activeTextField?.inputAccessoryView, 
              delay: 1.0)
    // ...
}

func textFieldDidBeginEditing(_ textField: UITextField) {
    activeTextField = textField // if keyboard is shown, show HUD.flash under inputAccessoryView
}
    
func textFieldDidEndEditing(_ textField: UITextField) {
    activeTextField = nil // if keyboard isn't shown, just show simple HUD.flash
}

This should work. If you don't create an inputAccessoryView the default is nil!

@PGLongo sorry, I didn't provide stuff like creating inputAccessoryView or setting textField delegate. Your example works absolutely the same as my screenshot above, if you make height smaller (I've tried 44). Well, that's full code:

import PKHUD

class ViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet weak var textField: UITextField!
    var activeTextField: UITextField?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        textField.delegate = self
        
        let customView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 44))
        customView.backgroundColor = .red
        textField?.inputAccessoryView = customView
    }
    
    @IBAction func logIn(_ sender: Any) {
        HUD.flash(.labeledError(title: "blabla", subtitle: "blablalba"),
                  onView: activeTextField?.inputAccessoryView,
                  delay: 1.0)
    }
    
    func textFieldDidBeginEditing(_ textField: UITextField) {
        activeTextField = textField // if keyboard is shown, show HUD.flash under inputAccessoryView
    }
    
    func textFieldDidEndEditing(_ textField: UITextField) {
        activeTextField = nil // if keyboard isn't shown, just show simple HUD.flash
    }

} 

@PGLongo I've pushed the project, if you want to play with it https://github.com/timqzm/PKHUD-above-inputAccessoryView

Maybe you want this:

class ViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet weak var textField: UITextField!
    var activeTextField: UITextField?
    let customView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 300))
    
    override func viewDidLoad() {
        super.viewDidLoad()
        textField.delegate = self
        customView.backgroundColor = .red
    }
    
    @IBAction func logIn(_ sender: Any) {
        self.activeTextField?.inputView = self.customView
        self.activeTextField?.reloadInputViews()
        HUD.show(.progress, onView: self.activeTextField?.inputView)
    }
    
    func textFieldDidBeginEditing(_ textField: UITextField) {
        activeTextField = textField
        
    }
    
    func textFieldDidEndEditing(_ textField: UITextField) {
        activeTextField = nil // if keyboard isn't shown, just show simple HUD.flash
        
    }

}

In this way the HUD replace the keyboard

@PGLongo
NO, I don't want replace the keyboard. I just want to see it like this:

Is there a way to do so?

You need to do this:
HUD.show(.progress, onView: UIApplication.shared.windows.last)

@PGLongo works perfectly, thx a lot!

You are welcome
