Seems like the usage of multiple DispatchQueues that are not the main thread is causing an issue listed here: https://stackoverflow.com/questions/26515968/swift-access-to-dictionary-of-a-singleton-causes-exc-bad-access/28910283

Possible fix: https://www.raywenderlich.com/5370-grand-central-dispatch-tutorial-for-swift-4-part-1-2
