If you don't want to use UITextField collection, you can use this,

@IBAction func buttontapped(_ sender: Any) {
    self.view.subviews.forEach({ item in
        if item.isKind(of: UITextField.self) {
            let txtItem = item as! UITextField
            txtItem.text = ""
        }
    })
}

UPDATE as @vacawama suggested,

@IBAction func buttontapped(_ sender: Any) {
    for case let txtItem as UITextField in self.view.subviews {
        txtItem.text = ""
    }
}

Assumption: All textfields are subviews of self.view directly. if textfields are subview of other customview, you should use that customview instead of self.view

In either case, OP might have to substitute another view for `self.view` if the `UITextField`s are subviews of another view (like a `UIScrollView` or `UIStackView`). – vacawama Jun 01 '18 at 10:22
@vacawama yes you are right – PPL Jun 01 '18 at 10:23

swift

create the IBOutletCollections or add all your textfield to one array for e.g

 @IBOutlet var storeAllTexts: [UITextField]!

on your button action method, call the following

   storeAllTexts.forEach { $0.text = "" }

objective C

create the IBOutletCollections

 @property (nonatomic, strong) IBOutletCollection(UITextField) NSArray *storeAllTexts;

on your button action

 for (UITextField *getCurrentText in self.storeAllTexts) {
  getCurrentText.text = @"";
}

For Objective C

for (id view in [self.view subviews])                                              
{
    if ([view isKindOfClass:[UITextField class]])                                       
    {
        UITextField *textField = (UITextField *)view;
        textField.text = @"";
    }
 }
