The position has been vacant for the past two weeks after Fani Madida stepped down from the hot seat, with the Dube Birds currently in the relegation zone on goal difference after 24 Premiership matches this season.
"Everyone at Swallows is delighted to welcome a coach of Rosslee's experience and winning record as the club looks to move away from the relegation places between now and the end of the season," read a statement on the Birds’ website.
With six game still to play this term, Swallows are in 15th position on the standings, which will mean they go in to the NFD/ PSL promotion play-offs if things stay as they are.
His first game will be on April 15 when Swallows take on Chippa United at Nelson Mandela Bay Stadium.
