How do i solve this error?

2016-08-30 09:14:55.856 BBS[476:159483] -[MosquittoClient initWithClientId:]: unrecognized selector sent to instance 0x15e3ba60

FYI: I have a project that is using Mosquitto library and it is working. However when i copy the original source code to another Mac for distribution or when i create a new project and integrate Mosquitto library into it, the error appear.

client = MosquittoClient(clientId: "client1") <-- Line that causes the error
client?.delegate = self
client?.port = 1883
client?.host = "someIPAddress"
client?.connect()

Do not hard code client IDs, they need to be different for every instance connected to the broker.

  • It is only an example here. For my project, the client id is a variable that takes in different client id from different user. And it still causes error – Wei Meng C. Aug 30 '16 at 06:37
