Value for frame.size.height is always the same regardless of height of view

I think the issue was by ths following , The thing is that constraints and layout are two different things. A constraint is just an instruction. It is not obeyed until layout time, which is much later.
So, you can set a view's height constraint, but nothing else happens at that moment. There is no point checking the view's height in the next line after you change the constraint, because nothing has happened yet.
code :

it should still fix some issue I`m getting 0 when I return this from my ViewController : , Height is a float. Use %f to log it.
Xcode: frame.size.height change makes view's height change in the downward direction?

like below fixes the issue Extend the origin upwards by the same amount you extend the size.
Something like:
code :
- (void)setVUMeterHeight:(float)height {
     if (height < 0)
        height = 0;

     const CGFloat kMeterBottom = 200;
     CGRect frame = vuMeter.frame;
     frame.size.height = height+10;
     frame.origin.y = kMeterBottom - frame.size.height;
     vuMeter.frame = frame;
}
What's the difference between UIView's frame.height and frame.size.height?

this will help It all started with Objective-C and CGRect. It only has two properties - origin and size. size is a CGSize which in turn has a height property. So it is common in Objective-C to get the height of a frame using:
code :
CGFloat height = frame.size.height;
CGFloat height = CGRectGetHeight(frame);
let height = frame.size.height;
let height = frame.height;
let rect = CGRect(x: 0, y: 0, width: 320, height: -40)
print(rect.height) // 40
print(rect.size.height) // -40

To fix this issue I have a ViewController (B) which is handled by a PageViewController which is inside another ViewController (A) and open it modal. I have centered the ViewController (B) exactly in the middle of the screen. This works fine. , Use this :

I wish this helpful for you I ran into this issue as well. intrinsicContentSize() has been changed to a property so you'd override it like this:
