By the time first-class football had resumed after the war, he became Arsenal's undisputed No. 1, and stayed there for the next few seasons. He had put his erraticness behind him, and he was a commanding keeper who was especially known for his aerial ability and assured handling of crosses, as well as his strong physical resilience. He won his second League title in 1947–48. After the arrival of Ted Platt in 1950, Swindin had to share the goalkeeper's spot for 1949–50, but played in both the 1950 and 1952 FA Cup Finals; Arsenal won the former against Liverpool, but lost to Newcastle United in the latter.
