Narrative:

Aircraft X IFR departure climb on course already coordinated with center and pointed out to the arrival sector to the north. There was aircraft Y holding VFR north of hill field not talking to approach. Aircraft Y's altitudes varied; and one departure expedited his climb on his own through 170 and told me he had the aircraft Y on TCAS. Aircraft X was 10 miles in trail and was a slower climber and I noticed that aircraft Y was turning south toward aircraft X so I stopped his climb and began pointing out the traffic. Once aircraft X had aircraft Y making an east bound turn at his one o'clock and about 4 miles in sight I decided to climb the aircraft X because it appeared aircraft Y was descending. Then aircraft Y was north bound and began to climb; once aircraft Y started to make the west to south bound turn I issued traffic again then stopped aircraft X at his present altitude. I issued the traffic and asked if aircraft X would like a turn out to the west not sure if he still had aircraft Y in sight. He requested a turn so I issued a left turn to 290; aircraft X advised me of a RA and I issued the traffic again. Then the ca went off on the scope and I saw aircraft Y make a right turn toward aircraft X so I issued the traffic alert. Aircraft X responded with a second RA.
