Crash in LDEventTrackingContext: Unrecognized Selector (v3.0.0) #173

Closed JUSTINMKAUFMAN closed 5 years ago

JUSTINMKAUFMAN commented 5 years ago

Is this a support request? Yes.

Describe the bug We have experienced several crashes on iOS over the last week on release v3.0.0 of the SDK.

It is not clear whether they are all related, however I am attaching the details we have here from our logs for all 3 crash types below.

To reproduce I have observed the first type of crash (see 1 below) running on simulator, but have been unable to establish consistent steps for reproducing it. Possibly a race condition?

Expected behavior Not to crash...
