With these it helps You have a couple of options to solve this layout issue:
Personally, I might try embedding these views in a UIStackView. The stack view will work to manage the vertical layout for you, allowing you to insert and remove subviews as needed. UIStackView is especially easy to work with from Interface Builder if you use Storyboards.

I wish this help you You could use something like this to loop through all UITextFields that are subviews of self.view and add their text to a NSMutableArray:

code :

for (UITextField *field in self.view.subviews) {
    if ([field isKindOfClass:[UITextField class]]) {
        if ([[field text] length] > 0) {
            [someMutableArray addObject:field.text];
        }
    }
}

Hope that helps The problem was you mapped first button's with label's top so it was not showing properly actually you need to assign first button's top equal to label's bottom:

code :

if(index == 0)
{        
    contentView.addConstraint(NSLayoutConstraint(item: button, attribute: NSLayoutAttribute.Top, relatedBy: NSLayoutRelation.Equal, toItem: preguntaLabel, attribute: NSLayoutAttribute.Bottom, multiplier: 1.0, constant: 8.0))
}
