According to Sport24, second-half goals from teenage midfielder Serge Gnabry and Ramsey put the Gunners on top at the Liberty Stadium before Swansea's Ben Davies pulled one back eight minutes from time.
Arsene Wenger's table-toppers held on to secure their fifth straight league win since an opening day defeat by Aston Villa, the report said.
Arsenal started the day on top of the table but only ahead of north London rivals Tottenham Hotspur on goal difference alone, the report added.
However, with Spurs held to a 1-1 draw by Chelsea earlier in the day, Arsenal kicked-off in south Wales knowing victory would give them a clear lead at the head of English football's top-flight, the report further said.
