Hello, I've built an iPhone app where there is a list of users that loads from the server (I'm using backend Quickblox) and there's an action that helps create a chat room. This action connects correctly in Xcode but when I run the app, it crashes and this error appears: libc++abi.dylib: terminating with uncaught exception of type NSException However, when I located the problem connection when the app isn't running it shows up as fine. It only shows an error when I run the app, and when I press on that connection within the app it crashes. I hope I'm making sense, I'm a bit of a novice and this problem is frustrating me because no matter how many times I check, the connection appears to be fine. It only shows up "This event connection is of an unknown type" when I run the app.
