MB AIR 13 (2011) should I upgrade to sierra?

[Uhi]

Hi,

I would like a to ask a question. I have a MB AIR 13 (2011) running El Capitan just fine. Recently I would like to use Xcode but I cannot install the newest version of it because it requires the newest os which is Sierra. So my question is: should I upgrade to Sierra? Will it affect the speed of my mac? I know it's not a modern model but I cannot afford a new one.

And did anyone with and older mac update to Sierra? How it works?

Thank you for your answer.

I have heard of people using Sierra on a 13 MB.
It should run it "ok" I personally don't know how well.
Here is how:
