Warning message in Xcode11.3.1 debug area

[sjacs5537]

Hi,
After I moved my project from Xcode10 to Xcode11.3.1, when magicalRecord run the following code in NSManagedObjectModel+MagicalRecord.m:
+ (NSManagedObjectModel *) MR_mergedObjectModelFromMainBundle { return [self mergedModelFromBundles:nil]; }

The debug area will show a message below:

CoreData: annotation: Failed to load optimized model at path '/Users/test/Library/Developer/CoreSimulator/Devices/DC44EC5B-292D-471B-84AA-AD71D08C8705/data/Containers/Bundle/Application/FCF9E085-001A-48B6-A67F-3EED6C0361A0/myapp.app/myapp.momd/myapp2.omo'

It did not happened in Xcode10, any fix for this issue?

Test device: iOS12.4

Thanks.
