The lawsuit was filed in August of last year, and arguments in court spanned most of May (and were conducted in-person, not virtually), and then the judge issued her decision today. That's not exactly lightning quick. The rate at which court cases proceed really depends a lot on the complexity of the case, the length of the discovery phase, etc. Both Apple and Epic didn't want to have a jury trial, so there also wasn't the matter of empaneling a jury.
