"I'll be forever thankful for the opportunities Syracuse provided. I believe it is time to challenge myself at the next level," Swider wrote Sunday on Twitter, adding that he would sign with an agent.
The 6-foot-9, 220-pound Rhode Island native transferred to Syracuse last year from Villanova and started all 33 games for the Orange in 2021-22. He averaged 13.9 points, second on the team to Buddy Boeheim (19.2), and topped Syracuse in rebounding, averaging 6.8.
Swider also shot a team-high 41.1% (81 of 197) from 3-point range and excelled toward the end of the season, when the Orange won six of seven before faltering. He went 31-of-55 (56.3%) from beyond the arc in a 10-game span that included a loss at Virginia Tech in which he missed all five of his attempts.
Syracuse finished 16-17, the first losing season in coach Jim Boeheim's 46 years.
The NBA draft is June 23.
