backgroundTask iOS Swift version
This is an updated Swift version of the example of the Infinite Running Background Task written in Objective C http://hayageek.com/ios-long-running-background-task/ Infinite task is based on playing blank audio file. My version is simplified to a minumum to run the task forever in the background. I also included a blank wav file that will be played forever until you stop the task. *Note: Battery consuming is 10% for 24 hours period.
