Narrative:

VFR weather at ZZZ. Asked approach for the GPS xx for practice. [They] cleared us for the approach. Leveled off at 3000 ft at ZZZZ. Captain armed the VNAV (vertical navigation) and I set MDA (minimum descent altitude). I was distracted by trying to locate VFR traffic in the pattern at ZZZ. Aircraft descended below final approach fix altitude 2300 ft at ZZZZZ1. I believe we were at about 1800 ft. We got a terrain alert and captain immediately turned off auto pilot and climbed to a safe altitude and leveled off. We were VFR at the time runway in sight and continued to land and captured the VASI. Cancelled IFR with approach prior to landing. I needed to pay more attention to the approach altitudes and automation modes. Pay less attention to traffic.
