I experienced a frustrating problem today wither with Xcode 13 and Xcode 13.1 rc that I have downloaded to test if the problem was presente also in the new version With a certain file Xcode sourcekitservice daemon went to a staggering 60-70 gb of memory causing the MacBook Pro m1 to freeze after a memory warning. After some investigation I found a weird problem (already signaled to apple bug reporting) with GeometryReader and frame.

you will see in this code three .frame commands. if you comment and uncomment these leaving only one active you will see that sourcekitservice will grow exponentially (beware, you could be obliged to restart your Mac by keeping pressed the power button) This behavior is really strange, and based on how you do the multiplication the system became unstable. Does it happen also to other? Could you try to load this in Xcode and test it?

Add a Commentif you specify the type :CGFloat in the let variable seems that the service doesn't grow up exponentially
