The goal was worthy of winning any game after some fine combination play on the edge of the Birmingham box between Jordan Obita and Liam Kelly. Kelly's back-heel played Obita into space, with the latter picking out Swift in the centre who provided a cool finish.
Despite late pressure from the Blues, Reading hung on to claim all three points in the midlands.
