EXC_BAD_ACCESS

[mohammdsss1]

My app was crashing without telling me where. So I turned the Address Sanitizer on for the scheme. When the app crashed again, the breakpoint was pointing to the setter property observer of Operation class as shown in the image below.

This is also reported on Crashlytics:

What I was doing is producing an operation from another one in a fast way (extensive taps from the UI). I don't know if there is anything else I can provide to debug this issue!
