Best laptop within these parameters?

It IS a bit of an ask, but I'm willing to go second hand if needs be.
I need a decent laptop with an i5 processor and 8gb of ram for about £300. Best I've come up with so far is the Lenovo Ideapad 310. Anyone got any better ideas?

Is a 2011/2012 Macbook Pro (upgraded to SSD and 8Gb of Ram) any good for working with Xcode?

This year I'm going to start college. I'm going to take a bachelor and then a master degree in Computer Engineering.

I recently bought a new windows laptop (because in almost all my subjects I'm going to use Windows). I bought a Lenovo Ideapad 720s with the following specs:
-16GB Ram
-512GB SSD
-Intel Core i7-7700HQ
-NVIDIA GeForce GTX 1050 Ti 4GB

But the point is that I would like to learn how to work with Xcode, a tool that is exclusive of MacOS. At this moment, I'm not able to buy a new 2018 Macbook Pro.

So the question is if a Macbook Pro from 2011/2012 would be any good to work with Xcode (till I save enough money to buy a full spec new Macbook Pro)?
I would upgrade that Macbook to 500SSD and 8GB/16GB of Ram.
