Self-interest mandated this resolution. Both companies were risking more than they stood to gain by winning their various suits.
Who nominally 'won' will depend on whether Apple is paying what it considers reasonable royalties going forward and whether the patent agreements allow it to utilize Qualcomm's IP in their own chipsets.
If Qualcomm has given up on tying patents to chips then it has effectively lost. If they can maintain that position with everyone but Apple, they'll probably be OK with the outcome.
Apple was forced to the table by its partner (Intel) being unable to supply 5G in a timely manner, so it may very well had to give up more than it otherwise would have.
