[Re-sending now that the lists are back up] Conditional NSExpressions (NSConditionalExpressionType) were added in 2015, but Apple’s predicate format syntax document* hasn’t been updated, so I can’t find any description of what the syntax is for them in a predicate string.
By reverse-engineering (creating a conditional expression programmatically and then calling -description on it) I found that the syntax “TERNARY(test, iftrue, if false)” works. But this is pretty ugly**; I was hoping there was a cleaner syntax like “test ? iftrue : iffalse” or the more SQL-like “IF test THEN iftrue ELSE iffalse”. Would anyone happen to know if there’s an alternate non-functional syntax? —Jens * https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/Predicates/Articles/pSyntax.html <https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/Predicates/Articles/pSyntax.html> ** Unless you’re a LISP fan, I guess _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
