Cannot call value of non-function type

Question

Having issues trying to convert this to Swift 3.0.

I have:

 public func calendarView(_ view: DDCalendarView, eventsForDay date: Date) -> [Any]? {
        let daysModifier = (date as NSDate).days(from: Date())
        //var daysMod = date.days(from: Date())

        //var newE = self.events(forDay: daysModifier as Int) as NSArray
        var Good = self.events(forDay: daysModifier) as Any
        var dates = [NSMutableArray]()
        var e:DDCalendarEvent

        for e in Good as! [AnyObject] {

            if e.dateBegin(isEqual(date)) as! Bool ==  true || e.dateEnd(isEqual(date)) as! Bool ==  true {
                dates.append(e as! NSMutableArray)
            }
   }

       return dates
    }

the condition if e.dateBegin(isEqual(Date)){} is giving this error. while in Objective-C Code Code is:

- (NSArray *)calendarView:(DDCalendarView *)view eventsForDay:(NSDate *)date {
    //should come from db ;) NOW using testdata
    NSInteger daysMod = [date daysFromDate:[NSDate date]];
    NSArray *newE = [self eventsForDay:daysMod]; //always today ;)

    NSMutableArray *dates = [NSMutableArray array];
    for (DDCalendarEvent *e in newE) {
        if([e.dateBegin isEqualDay:date] ||
           [e.dateEnd isEqualDay:date]) {
            [dates addObject:e];
        }
    }
    return dates;
}

and its returning Bool Value for isEqualDay Function

- (BOOL)isEqualDay:(NSDate *)date {
    NSDateComponents *compA = self.currentCalendarDateComponents;
    NSDateComponents *compB = date.currentCalendarDateComponents;
    return ([compA day]==[compB day] && [compA month]==[compB month ]&& [compA year]==[compB year]);
}

Any Solution for this?

Answer 1

This line:

if e.dateBegin(isEqual(date)) as! Bool ==  true || e.dateEnd(isEqual(date)) as! Bool ==  true {

should be:

if e.dateBegin.isEqualDay(date) == true || e.dateEnd.isEqualDay(date) == true {

This assumes you have also translated the isEqualDay: method as an extension function on Date .

BTW - there are many other problems in your translation. The above only covers that one specific line you ask about in your question.

The following should be what you want:

public func calendarView(_ view: DDCalendarView, eventsForDay date: Date) -> [Date] {
    let daysModifier = date.days(from: Date()) // return Int
    let newE = self.events(forDay: daysModifier) // return [DDCalendarEvent]

    var dates = [Date]()
    for e in newE {
        if e.dateBegin.isEqualDay(date) == true || e.dateEnd.isEqualDay(date) == true {
            dates.append(e)
        }
    }

    return dates
}
