Repeat HMTimerTrigger On multiple days (Ex: Every Monday,Wednesday… like in iOS 10 Home app)

Since last 2 days I have been trying to implement the HMTimerTrigger repeat functionality. My requirement is I have to repeat the Trigger on every monday,tuesday and friday. What I found is I can add only one day(Monday or Tuesday ... but not Monday AND Tuesday) like below.

  unsigned flags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitWeekOfYear | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute;
 NSDate *fireDate = [NSDate date];
 NSDateComponents *recurrenceComponents = [[NSDateComponents alloc] init]; 
recurrenceComponents.weekday = 2; / For Monday
NSDateComponents *dateComponents = [[NSCalendar currentCalendar] components:flags fromDate:fireDate]; 
fireDate = [[NSCalendar currentCalendar] dateFromComponents:dateComponents]; 

HMTimerTrigger *trigger = [[HMTimerTrigger alloc] initWithName:triggerName.text fireDate:fireDate timeZone:nil recurrence:recurrenceComponents recurrenceCalendar:[NSCalendar currentCalendar]];

Thank you for reading my post. Any ideas/suggestions would be very helpful.
