Can anyone help to understand what is causing this warning message on this SampleCode.
- it happens when data in table gets updated
- it happens when I have lot of items in table and search for lets say # 6543 and then clear the search.
"WARNING: Application performed a reentrant operation in its NSTableView delegate. This warning will become an assert in the future."
If there are just few items in table, the warning is not there.
And it started when updated to Xcode Version 14 and upward
