The Turkish side will also have the option to purchase Ayew on a permanent deal at the end of his loan spell, as Swansea are keen to keep the high-earning forward off their wage bill as they look to rebuild in the Championship.
The Swans re-signed Ayew from West Ham in a club-record deal in January 31 on a three-and-a-half-year contract. The 28-year-old forward returned to Wales having left the Swans to join the Hammers for £20.5 million 18 months earlier.
Former Östersunds FK and current Swansea City manager, Graham Potter, praised Ayew's professionalism in a statement on Swansea's Official Website.
“I understand the circumstances of the move – it’s part of the restructure of us going forward,” he said.
“From my perspective he has been brilliant. He has applied himself in training, supported what we are trying to do and been very professional.
“He has been a joy to work with and we wish him the best.”
