Obj class of third party Undefined in nextcloud/talk-ios

i’m getting this error in nextcloud/talk-ios app( https://github.com/nextcloud/talk-ios)

Hi @Tvisha_Dhami :slight_smile:

What version of the app are you trying to build? Master branch?
You should use the latest XCode version (11) if you are building the master branch.

Also, you should get project dependecies before building the project using the following commands as described in the README.

$ pod install
$ git submodule update --init
