Does Crashlytics generates crash report when system terminates iOS application on low memory condition and application is in:
Based on the information I was able to find, the answer is yes, it does but only if the app was running in the foreground when the termination took place.
However, it also seems there is no sure-fire way to detect this kind of crash. Crashlytics and other crash reporting framework analyze crash data after the fact, which is to say the next time the app is run. In this case, they try to eliminate other potential termination reasons first and if nothing else matches, then it's probably an out-of-memory termination.
