Question about Xcode version and Mac version.

I would like to learn IOS development. However there is something that I cannot grasp.
I recently purchased a used Imac. It is a late 2013 model that will not be eligible for the Big Sur updae.

My question is what happens later down the line when Xcode updates require Big Sur? Am I going to have to purchase a newer updated Mac in order to keep building apps and releasing apps onto the store?
Ultimately, you will have to, because it will be required that apps submitted to Appstore use recent Xcode version, hence BigSur.

It may take a few years, but it will come.
