HuggingGeometryReader
HuggingGeometryReader is a SwiftUI package that has a different sizing behavior then the official GeometryReader
.
The problem
We use GeometryReader
to find out view’s size. However, GeometryReader
attempts to match the parent size, as indicated in the comments for GeometryReader:
This view returns a flexible preferred size to its parent layout.
This is sometimes not what we want, for example:
If we want to get the height of a Text
as below
And with the origional GeometryReader
, we might have something like this:
GeometryReader { proxy in
Text("Hello, height is \(proxy.size.height)")
.padding()
.background(Color.green)
}
.background(Color.red)
But the result would be something like this:
The size we get is actually the red part, that’s not what we want. Also, the GeometryReader
occupies the whole screen and breaks the layout.
A simple example
This package solves the above problems with simple usage:
HuggingGeometryReader { size in
Text("Hello, height is \(size.height)")
.padding()
.background(Color.green)
}
.background(Color.red)
This code will have the result of the first image above.
