Hey

Did the issue resolved ?

[cegprakash]

In the documentation it is mentioned wrongly that swagger supports all rest frameworks which are 3.5+.

You cannot get swagger 2+ get working with very old rest framework (i.e. 3.5+). I resolved it by downgrading my swagger to very old version (as in my case I couldn't upgrade my rest framework). Note that you've to follow older documentation to setup older version of swagger. Also note that older version of swagger don't have a great UI and great features that it has now.
