There's 40 GB space available on disk but installing xcode from AppStore still shows 'We could not complete your purchase. There is not enough disk space available to install the product'
MacBook Air 13″, macOS 12.0
That 40GB is likely still not enough to install Xcode and maintain a running operating system. I advise you to free up even more storage and try again. The Xcode installation takes a long while to install too…
If you are still on macOS 12.0, and even though that is the minimum operating system version to install Xcode 13.3, I recommend that you update the operating system to 12.3.1.
Current Xcode is itself 36 GB.
Your system is seriously under-configured and under-provisioned for app development.
xcode isn't getting installed though I have enough space
