I had that surgery and will need the same surgery on my right shoulder soon!
Took 2 days off, 1 week was spent in the gym doing nothing but cardio and legs, by week 2 I had incorporated light arms/back, week 6 or so bench and shoulder work.
Its been almost 3 months now and I’m doin great 
Still stiff in the morning mostly, takes more warming up that it used to, but I’m back at it 100%. EDIT: Scratch that, I can’t do wide bench. Only extremely close grip bench with the BB, or supinated grip with DBs (I can go much heavier with DBs for some reason).
Pain was bad for the first week, invest in button up shirts! Also, I didn’t have a slap repair, my bad. Just distal clavicle resection and subacromial decompression.
Slap tear repair should bump the healing up a couple extra months for heavy lifting, but you’ll probably be good for light weights by at most month 3.
EDIT here’s my thread on my distal clavicle resection:
