Originally created by @laeroah on GitHub (Feb 8, 2017).

Some weird crash happening with version 3.0.2. The same code works fine in 3.0.1
With 3.0.2, the app starts to crash at this line:
_dataStack = DataStack(modelName: "AppFriendsCore", bundle: bundle, migrationChain: nil)
I also tried to explicitly specify the migration chain here, but it still crashes.
The same code works fine in 3.0.0 and 3.0.1

@laeroah Can you add an Exception breakpoint and print the message argument when it crashes?

@JohnEstropia the message is
"Invalid migration chain passed to the DataStack. Check that the model versions' order is correct and that no repetitions or ambiguities exist."

Hmm there isn't any change with migrations between 3.0.1 and 3.0.2.
I can't reproduce it on my side either.
Can you try quitting Xcode then deleting the derived data?

I tried cleaning and restarting Xcode, but still crashes. The same crash happens in two of my apps after they update Corestore to 3.0.2. I don't think it's crashing due to the migration anymore, it's more like a memory issue.

@laeroah Okay thanks. I'll rollback the update today, sorry about that. In the mean time please use the 3.0.1 release.

@JohnEstropia sry, just want to check on this. Is it fixed on 3.0.2?

I reverted the 3.0.2 changes and released it as 3.0.3 so please update to the latest version. So far I haven't reproduced the problem on my dev environment yet so I'll probably defer that update until I successfully find the cause.
