Warning on macOS: Invalid frame dimension (negative or non-finite)

[patrick-fu]

On macOS 11.1, when a View is loaded for the first time, the size obtained by GeometryReader is incorrect, resulting in a negative frame value, causing this warning. The real size can only be obtained the second time, as shown in the screenshot.

Same on tvOS

try this, it works for me ~

.frame(width:abs(self.contentWidthFor(geometry)))
