I am trying to update Xcode to 8.0. My OS is 10.11.6 El Capitan. However I am getting:
We could not complete your update
There is not enough disk space available to install the product.
I have got 14.22 GB free space. How much do I need?
UPDATE: I do not know the exact figure, though I did manage to update with 17.21 GB free space later on.
