Why can't I download an older version of Xcode?

I just upgraded from a mid-2014 Macbook Pro to a 2020 M1 Macbook Pro (yay!) & I used migration assistant & an external hard drive to transfer my data. Everything went smoothly expect Xcode didn't transfer.

I was using Xcode version 11.6 on my old Macbook because I needed it for a certain framework for a class. I tried downloading the Xcode_11.6.xip & it said Failed-Network error. Is there any way I can properly download it?

Try again when network is stable enough.
Did you try to download from here :

I don't think it's possible to run Xcode 11 on an M1 Mac.
But if you succeed, please let us know!
Did you make any progress on this?
