What are the common bugs in iOS apps

After our analysis of common bugs in Android, we did the same analysis for iOS as well. Here are our findings.

API bugs are the most common bugs in iOS and contribute 45% of all issues reported, followed by crashes at 25%. Memory leaks contribute 10% of bugs and came third in the list. Frame skips came next at 5%.
 

The data is based on analysing 2M iOS bugs reported in Finotes as of 2 June 2020, 11.59PM GMT. Only native apps built using Objective C or Swift were considered.
 

It's interesting to note the lower rate of memory issues and crashes reported in iOS compared to Android (Click here to read about common bugs in Android). Does that convey something about the way apps are created in both platforms?
