My app's crashlytics board shows a top crash where the description is mentioned as below CoreFoundation -[CFPrefsSearchListSource addManagedSourceForIdentifier:user:] Fatal Exception: NSInternalInconsistencyException  UITableView dataSource is not set This is not reproducible at any definite steps, and from the logs which I put, it looks like it happens in most of the view controllers. Have any one got similar crashes and any work around for this? Thanks in advance!
