NSPredicateEditor not handling integer values

I have a fairly simple NSPredicateEditor setup, and any String based predicates work fine, but integer predicates are causing an exception.

The predicate editor appears to be configured correctly…

…but whenever I choose one of those left hand values from the predicate editor, I get this exception, like the predicate editor is treating the number as a string:

2016-10-29 10:48:12.416 PredicateBarTesting[29041:303] -[__NSCFNumber length]: unrecognized selector sent to instance 0x37 2016-10-29 10:48:12.419 PredicateBarTesting[29041:303] An uncaught exception was raised

Full exception: http://d.pr/n/XT97

Any ideas?

Solution

  • The left expressions in the predicate editor row template shoud be 'Keypaths' instead of 'Contant Values' (strings).
