swift - No such Module Error

Question

I am working on a chat app using Swift, and cocoa pods and I keep getting this issue. It says no such module JSQMessagesViewController, and the pod file is set up just like the tutorial wants me to do it. If you need me to show you the pod file just let me know and I will put it in there.

Thanks Luc

Here is the code.

let channel = SCChannel(name: syncanoChannelName)

let incomingBubble = JSQMessagesBubbleImageFactory().incomingMessagesBubbleImageWithColor(UIColor(red: 10/255, green: 180/255, blue: 230/255, alpha: 1.0))
let outgoingBubble = JSQMessagesBubbleImageFactory().outgoingMessagesBubbleImageWithColor(UIColor.lightGrayColor())
var messages = [JSQMessage]()

Do the following things and you can import any swift file from "Pods"

1) Clean your project

2) Make sure that all your "Pods" > "Build Settings" > "Build Active Architecture Only" is set to "NO".

3) Don't run, just build your project.

4) Now, import any file from "Pods" to any swift file

E.g.: import JSQMessagesViewController

5) Again, build project and it will work as expected. Finally, you can access it properties

Hope this helps!
