Error when calling delegate

[Rodolfocartas]

I keep getting this error. I thought the problem was that delegate was getting deallocated before the library gets to call the delegate method. I moved the delegate to a singleton object and the error is still surfacing. The problem seems to be related to a cast, but I haven't so far found it.

Hello, can you share your code? Also did you call every delegate function ?

[Rodolfocartas]

I checked the code. The library is casting an Error into a String thus causing the crash. The problem occurs in StompClientLib.swift:183.

Thank you for fixing the code :) I'm going to make a new version with your correction
