I was banned to enter SA for one year after I overstayed by one day.
Do African countries share immigration data with European countries? And is there any need to disclose the ban on a UK visa application, when it has ended?

Yes, your South African ban could harm your chances of getting a UK visa.
AFAIK African countries do not routinely share immigration data with European countries. However, when applying for a UK visa you are obligated to disclose all overstays and bans, no matter the reason, how long ago the overstay, or how long a ban was for. Deliberately not disclosing counts as deception, and would result in a lengthy ban if discovered.
