Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

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
messageargument when it crashes?@laeroah commented on GitHub (Feb 8, 2017):
@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."
@JohnEstropia commented on GitHub (Feb 8, 2017):
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?
@laeroah commented on GitHub (Feb 8, 2017):
@JohnEstropia ok, will give it a try. thanks
@laeroah commented on GitHub (Feb 8, 2017):
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.
@JohnEstropia commented on GitHub (Feb 9, 2017):
@laeroah Okay thanks. I'll rollback the update today, sorry about that. In the mean time please use the 3.0.1 release.
@JohnEstropia commented on GitHub (Feb 9, 2017):

@JohnEstropia commented on GitHub (Feb 9, 2017):
thanks!
@laeroah commented on GitHub (Feb 9, 2017):
@JohnEstropia thank you!
@laeroah commented on GitHub (Feb 13, 2017):
@JohnEstropia sry, just want to check on this. Is it fixed on 3.0.2?
@JohnEstropia commented on GitHub (Feb 13, 2017):
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.
@laeroah commented on GitHub (Feb 14, 2017):
Thank you! 3.0.3 works for me.
