There are instances where building against an older SDK is preferable/necessary, and I lament that Apple no longer includes the last few SDKs in Xcode (instead only including the newest SDK).  But for 99% of the time, using the newest SDK is all you need.  Regardless of the SDK version you need, you should always be setting the deployment version to the oldest OS version you want to support at runtime.

If you really need/want to build against an older SDK, then you can:
 1) hack Xcode, and risk any incompatibilities/bugs that ensue.
 2) use an older Xcode, which may also mean using an older macOS. This is where having a collection of buildbots/VMs comes in very handy.

Seems to require a google login.  The wikipedia Xcode article also lists SDK versions included, example:
