Swift has been recognized as the Naval Air Forces, U.S. Pacific Fleet landing signal officer of the Year, and was presented the Commander Michael G. Hoff Award as the U.S. Pacific Fleet attack aviator of the year.[4]
In December 2015, Swift warned of a possible South China Sea arms race increase.[6]
On March 1, 2017, Swift received the Gray Eagle Award as the Naval Aviator on continuous active duty in U.S. Navy or Marine Corps who has held that designation for the longest period of time.[7]
On September 25, 2017, Swift announced that he would retire after he was notified by then-Chief of Naval Operations, Adm. John Richardson, that Swift would not be nominated to take over leadership of the United States Indo-Pacific Command, the inter-branch theater command for the Pacific region.
