What were you doing before this error -- invoking a server method? If so, what does the server method look like and what does it return?

[rsdev-darshan]

i am getting blank in msg..

[rsdev-darshan]

it was working fine, but it stopped working suddenly... after i updated the pods

[adamhartford]

What does your Podfile look like? Does this happen immediately or only after invoking a server method, or something else? Is it reproducible every time?

[rsdev-darshan]

immediately on calling connect method...

[rsdev-darshan]

And actually its fixed now..
I rolled back to swift1.2 and again installed swift2 pod.. and it started working.
