Swift spent five years playing keyboards for The Shins, from 2011 to 2016.
His friend and music partner Dan Auerbach of The Black Keys shared his grief with fans on Instagram, pairing a picture of the duo with the caption: 'Today the world lost one of the most talented musicians I know'. "He's now with his Mom and Sister", Auerbach, 39, wrote on Tuesday, July 3.
Last June, a GoFundMe page was set up to help him pay for medical bills as he recovered from a "serious medical condition".
A representative for Swift said he died on Tuesday morning in Tacoma, Washington.
"Dear friends of Swift, Richard needs your love and support now as he is up against some tough odds". In 2001, he moved to California and began self-releasing his home-recorded music - much of which was collected in The Richard Swift Collection, Vol. 1, a collection that Secretly Canadian released after Swift signed with the label in 2005.
At that time, a GoFundMe was created to help Swift with medical expenses.
Eventually, Swift would go on to found his own recording studio, National Freedom, in Cottage Grove, Oregon, overseeing records by Foxygen, Sharon Van Etten, Guster, Pure Bathing Culture, and many others. In just 13 days the campaign raised over $87,000. "He is receiving excellent care in Tacoma Washington and everything is being done to allow his body time to fix and heal", a description on the GoFundMe page read.
Swift's most recent solo effort was 2009's The Atlantic Ocean.
