Issue with iOS build on meteor version 2.3.6

recently i updated meteor version from 2.0 to 2.3.6,
now i am getting below error while building iOS,

No known instance method for selector ‘userAgent’

in CDVFileTransfer.m file.

FYI: i am using plugin cordova-plugin-file-transfer version 1.7.1 for file transfer

Thanks in advance.
