JUCE Assertion failure in juce_AudioProcessor.cpp:691

I’ve made a plugin and am now trying to run it on iOS. The plugin works as a VST and AU, and it almost works as an iOS app, but after successfully building the app Xcode spits out:

JUCE v5.0.2
JUCE Assertion failure in juce_AudioProcessor.cpp:691

This line is the reset() function, which is overridden in my own processor. I thought the problem might be that my IIRFilters were not being reset, but that is not the issue. Also, I can open the app on my device after getting this error, but I am unable to use the app as interapp audio effect (fails to load/crashes garageband)t, which I assume is related to this JUCE error. I am not sure what is going on since the program works fine as a plugin. I would rather not include code, as I would have to include the entire project, but if anyone has any possible solutions/pointers, they will be greatly appreciated.
