Eder has left Braga to join Swansea City for an undisclosed fee, the Portugal forward signing a three-year contract at the Liberty Stadium.
Garry Monk has been busy adding to his Swansea squad following last season’s record eighth-place finish in the Premier League.
Andre Ayew, Franck Tabanou and Kristoffer Nordfeldt have already completed moves to Swansea and Eder will now join them after ending his three-year stay with Braga.
The 27-year-old boasts 18 caps for Portugal and scored his first international goal against Italy last month.
Eder contributed 10 goals in 29 Primeira Liga appearances last term for Braga. He previously represented Academica in Portugal’s top flight.
