Build successful but unable to run on iOS simulator

Question

I am making a demo of cordova app. The console log is showing me build successful but after sometime it shows this error and run fails :

2016-07-30 09:34:47.609 instruments[9268:1431174] WebKit Threading Violation - initial use of WebKit from a secondary thread. Instruments Usage Error: Unknown device specified: "B7257830-92A2-4C85-A4BA-342D7237F9A8"

Known Devices:

test's iPhone (8.4.1) [7fdfcc5aaeb179fdb53a86343ba18796a1825bc4]

The error is to replace UDID with known devices but I am unable find the file where it is mentioned.

Please share the path of file or file name or anything related to this error. Thanks in advance.
