I was watching a trainee in Sector X. He was having issues giving a pop up IFR clearance to an aircraft. As he was trying to figure it out I saw Aircraft Y to the south west of the airport at 075 and Aircraft X was headed south bound climbing to 080. I initially thought it would not have been a factor; however; I then heard the trainee give the IFR clearance the wrong altitude and issued a climb into another sectors airspace; IFR. I went and corrected it to avoid a potential airspace violation or worse. As soon as I fixed that situation I saw that Aircraft Y had climbed to 080 and was headed right at Aircraft X. The trainee issued traffic to Aircraft Y and Aircraft Y said he the airbus (Aircraft X) in sight. Aircraft X then said that he was responding to an RA. The trainee then told Aircraft Y to descend for traffic. I keyed up and told Aircraft X to report complete with RA and that the traffic had Aircraft X in sight. Aircraft X said he was going to file a near midair.Aircraft Y should have been capped at a VFR altitude and coordination should have been made to keep Aircraft X climbing. Trainees should be competent at issuing an IFR clearance prior to a control position.
TRACON Controller reported an IFR pop up aircraft was given an IFR altitude resulting in an airborne conflict with an IFR departure.
