I have released one version on my Application on iTune and is in process to release second one. Now I have uploaded the the .ipa file of the application and switching on for internal testing. But the application is not appearing on Testflight app of internal tester. I am uploading the .ipa file through Xcode 6.1 and also trying with Xcode 6.3.

If you've uploaded a build for the next/new version, you should see it at the top of the list of builds under the "Prerelease" menu for your app.
Assuming you're Build is in the list, check the "Internal" column for that build. If it says "Invite Testers", then that build is not yet active. What you probably need to do then is click the build number and make sure all the fields are filled out - especially "What to Test" - and then click the Save button. When you go back to the Builds list, it should now say "Active (30 Days Left)" under Internal. And should show up for testers in the TestFlight app.
I've noticed that sometimes I need to go through this process for a new build (even on a version I've already been testing) and sometimes I don't. I haven't found the pattern but it's tripped me up several times.
