```swift

        internalQueue.async {
            let newWrite = WriteItem(tag: tag, timeout: (timeout > 0.0) ? .now() + timeout : .distantFuture)
            self.scheduledWrites.insert(newWrite)

Console log: CocoaMQTT was compiled with optimization - stepping may behave oddly; variables may not be available.

I'm also encountering both crashes you posted @sadeghgoo related to this function and the scheduledWrites property. Looks like this property is overloaded with items and it leads to a memory issue. Did anyone find a fix?
