I want to know that is it possible to adjust `height` and `width` in proportion according to superview in `SwiftUI` to any `UIControl` ?

As we are doing like :

```
let txtFld = UITextField()
txtFld.frame = CGRect(origin: CGPoint(x: 0, y: 0), size: CGSize(width: self.view.frame.width/2, height: self.view.frame.height*0.1))

```

I know we can somehow achieve to adjust width by using `Spacer()`, `.padding` and `edgeInsets`. But what about `height`? I have seen lots of tutorial for `SwiftUI`, everywhere `height` is static. Even on Apple’s site. [SwiftUI Tutorials](https://developer.apple.com/tutorials/swiftui/creating-and-combining-views#compose-the-detail-view)

If anyone have knowledge about how to set height in proportion with view’s height, please share here. Because at some point we need like that. For ex. If it needs to make button according to device height. (Let’s say in iPhone SE = 40, iPhone 8P = 55, iPhone X = 65)

Hi @vimipatel,  
what you are looking for is a GeometryReader object. ([Apple Developer Documentation](https://developer.apple.com/documentation/swiftui/geometryreader))

cheers,
