I'm playing with JSQMessagesViewController. My first project I did using Raywenderlich's Firebase Tutorial: Real-time Chat tutorial.

Then I created a new project to play more with JSQMessagesViewController. And in this new project I'm having issue now.

After I import JSQMessagesViewController and add it as a super class for my ViewController, I got this error in my console -

Assertion failure in -[NewProject.ViewController viewWillAppear:], /Users/Downloads/ChatChatFirebaseTutorial-finished/Pods/JSQMessagesViewController/JSQMessagesViewController/Controllers/JSQMessagesViewController.m:233 2017-05-30 20:43:44.498 NewProject[10688:314277] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: self.senderId != nil'

I see message from ChatChatFirebaseTutorial(am I right?) my previous project in my new project.

So, I deleted everything what was about ChatChatFirebaseTutorial and even more from my mac. It didn't help. I uninstalled and installed pods from project and mac few times. It didn't help.

Did anyone has this issue before? If yes, how did you solve it?

The Library requires that you set a senderID for the current user. This can be done by adding a function like this to your class 

override func senderId() -> String {
    return "UNIQUEID"
}

I would use something you know is going to be unique such as an email or a unique Id you generate just associated to the user so you can determine who sent the messages.
