Aircraft X was on an assigned vector for a visual approach for Runway 05R. I was giving a detailed relief position briefing to a Controller who had not been in the facility for a significant amount of time. I got a conflict alert for Aircraft X; issued the traffic alert; [and] then suggested a 230 heading to miss the VFR traffic. The pilot and I seemed to step on each other's transmissions. I instructed the OSIC [Operational Supervisor in Charge] that Aircraft X indicated they received an RA (Resolution Advisory) for that traffic. I found out later the pilots of Aircraft X were elevating the RA to a NMAC. I have no recommendations to add.
TRACON Controller reported an airborne conflict which ended up being a NMAC.
