60gb space gone after Xcode update

So what?

That's normal - mark this as the correct answer

The incoming update is 3.6 gb but 60 gb of space is gone, why?

Hi,

I bought 256gb m1 processor and 150gb was free. When xcode was already installed in it, 150 gb was free. The update came to me, the remaining space is 80 gb, what makes sense?

Hello, I have removed the application now, the space is still 45 GB. I regret that I bought it. No data in backup?

I bought 256gb m1 processor and 150gb was free. 

So, Xcode was not installed at that time ? Then it is not an update, it is an initial installation (your OP was confusing). Hence using 60 GB is normal.

That just means you have not removed everything. You may find useful info here: https://developer.apple.com/forums/thread/110227
