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?

Hi! I'am use ListMonitor in my project. In Xcode 11 when I create ListMonitor, it loads all object from database. In Xcode 12 it ignored existing objects and load only new created.
I create demo project to illustrate this

I'll take a look
@JohnEstropia commented on GitHub (Aug 28, 2020):
@iEdward Thanks for the report.
Yeah this is weird. Can you reproduce it on any device?
It seems to be a simulator bug because I can't reproduce it on my iOS 13 iPhone.
It doesn't seem to be an
NSFetchedResultsControllerissue as well after trying out a plainNSFetchedResultsControlleron iOS 14 simulator.The demo apps seem to work properly as well 🤔
@iEdward commented on GitHub (Aug 28, 2020):
It reproduced on my device -
iOS 14.0 (18A5357e)
Model: iPhone X (Model A1865, A1901, A1902, A1903)
In Xcode 12b6 still reproduce.
My application build in Xcode 11 and downloaded from TestFlight works fine on iOS 14. If I build it in Xcode 12 - stop working.
@JohnEstropia commented on GitHub (Aug 28, 2020):
Thanks, so I guess this is an iOS 14 issue.
I'll try to investigate further
@JohnEstropia commented on GitHub (Aug 28, 2020):
Submitted to Feedback Assistant for now (FB8563134). Hope they take a look ASAP

I'm in a similar situation, using
ListPublisherin iOS14 I can't fetch the data, but the same query statement to fetch the quantity is normal. After a round of testing, it was confirmed that thefetchBatchSizeproperty was set to cause the problem, and a developer has reported back to Apple!https://developer.apple.com/forums/thread/658717@JohnEstropia commented on GitHub (Sep 6, 2020):
@skytoup Thanks for the info! I'll take a look and see if we can find a temporary workaround within CoreStore 👍
@JohnEstropia commented on GitHub (Sep 6, 2020):
Oops, It sounds like they fixed it on beta 7. I'll confirm
@JohnEstropia commented on GitHub (Sep 19, 2020):
This should be fixed in the GM release so I'm marking this as resolved. If you are still having issues please submit a bug report to Apple
