Swinkels spent the second half of last season with Bristol Rovers, where he played in 18 matches and scored two goals.
According to Exeter City's manager, Gary Caldwell, Swinkels was a key target for the team all summer.
Caldwell believes that Swinkels' experience, despite the challenges he faced with Bristol Rovers, will be beneficial for him at Exeter City.
He thinks Swinkels will make a significant impact on the team, both as a centre-back and a left centre-back.
Caldwell considers Swinkels an important signing for Exeter City.
