On the 30 August 2011, it was confirmed that Salomonsson had signed for Allsvenskan rivals IFK Göteborg. During his first time in IFK Göteborg, he played a small role and acted as back-up for Adam Johansson. However, when Johansson left the club, he became the first-choice right back and in the 2012 season he played 27 matches when IFK finished in 7th place. Before the start of the 2013, he wasn't the first-choice anymore with the comeback of Adam Johansson, the arrival of Ludwig Augustinsson and Mikael Dyrestam already being in the squad. However, because of injuries, he played 28 matches that season, most of them as defender, but some as a right winger. In the 2014 season, he once again started the season as the second-choice, but in the summer the reclaimed his place in the starting-eleven and he was a big contributor to IFK once again qualified for UEFA Europa League qualification. On 30 September 2014, he signed a new contract, keeping him at the club until the end of the 2018 season.
