Darius Wade added 155 yards passing and a touchdown.
The Eagles defense dominated Maine, holding the Black Bears to just 91 yards of total offense, including seven yards rushing.
Maine led 3-0 after the first quarter on a 39-yard field goal by Sean Decloux with 11:05 left.
Boston College took the lead with 26 seconds left in the first half on an 11-yard pass from Wade to Swigert. Wade rolled out to the left and Swigert made the diving catch. The touchdown came on the Eagles' third trip inside the Maine 20.
