The Swans stated on their website that Fernandez has signed a four-year deal for an undisclosed fee, subject to international clearance.
The 25-year-old passed a medical earlier this week, and he is expected to be in Swansea's squad for their Barclays Premier League game against Burnley on Saturday, when manager Garry Monk will look to build on last weekend's 2-1 win at Manchester United.
