Swords was born and grew up in
Fall River, Massachusetts, US, an early hotbed of U.S. soccer. In 1903, Swords joined Whittenton Athletic Club of
Taunton, Massachusetts. After one season, he jumped to his hometown-based
Fall River Rovers of the New England League. In 1909, the Rovers won the league title. In 1910, he moved to the
Philadelphia Hibernian of the
Eastern Soccer League. After two seasons, he moved to the
New Bedford Whalers for the 1913 season. However, he was back with the Fall River Rovers in 1914 and would remain with the team until he retired in 1920. During his second stint with the Rovers, Swords experienced some of his greatest achievements when the team went to three consecutive
National Challenge Cup finals between 1916 and 1918. In
1916, the team fell to
Bethlehem Steel. Then in
1917, they redeemed themselves when they defeated Bethlehem to take the Cup title. The two teams met again in
1918. This time Bethlehem won in a replay after the two teams played to a 2–2 tie in the first game. In this second game, Swords' brutal tackle knocked out the Bethlehem goalkeeper. ==National team==
