So another few hours digging into internet search results and trying things and I sort of have this working. <pre><code>NSDate * userDate = [NSDate dateWithNaturalLanguageString: inWhenString]; NSDateComponents * userDateComponents = [[NSCalendar currentCalendar] components: NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit fromDate: userDate]; NSDate * dayDate = [[NSCalendar currentCalendar] dateFromComponents: userDateComponents]; dNSLog(@"date %@", dayDate ); NSString * formatStr = [NSDateFormatter dateFormatFromTemplate: @"yyyy-MM-dd" options: 0 locale: nil]; NSDateFormatter * formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat: formatStr]; NSString * dayStr = [formatter stringFromDate: dayDate]; dayStr = [dayStr stringByAppendingString: @"*"]; dNSLog(@"dayString: %@", dayStr ); NSPredicate *p1 = [NSPredicate predicateWithFormat: @"%K >= CAST(%f, \"NSDate\")", @"kMDItemAccessedDates", [dayDate timeIntervalSinceReferenceDate] ]; NSPredicate *p2 = [NSPredicate predicateWithFormat: @"%K <= CAST(%f, \"NSDate\")", @"kMDItemAccessedDates", [dayDate timeIntervalSinceReferenceDate] + 86400.0f ]; predicate = [NSCompoundPredicate andPredicateWithSubpredicates: @[p1, p2]]; </code></pre> There may be other issues with this whole approach (based on how the app updates this array of dates) that may require me to do something else entirely, but this seems to answer the original question of how to fetch only items that were accessed on a particular day. The key was the <code>CAST(%f, \"NSDate\")</code> I believe. There might still be a better way, but I thought I'd put this up here in case someone else is digging around for any clues.

1. COThat's very interesting. I had not seen CAST before. I'm glad you got it working.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
