Right version for Swift 4

[elchris78]

Hi there!
I just updated a project from Swift 3 to Swift version 4 in which I was validating all text fields alrigth with the help of this awesome library, but now I just updated the project, EGFormValidator started to chash here:

This is my pod file config:

And the pod version just updated for this pod is marked as 2.0.0. (in Swift 3 was 1.0.0)
How can I do to fix this? which pod file version is the right one?
Thanks in advance..
