It's the constant problem for libraries: developers relying on implementation details that were not guaranteed. Microsoft has traditionally bent over backwards to support such misbehaving applications (eg simcity getting application-specific code in windows 95 release [0]), whereas Apple has traditionally allowed things to break. It shouldn't be very surprising they continued that behavior today, unless it's the case that it was guaranteed in ios12 and broken in ios13.
