    If someone is interested in a Swift solution, then use:

    import Foundation
    
    let weekday = NSCalendar.current.component(.weekday, from: Date())
    print(weekday) // => prints the weekday number 1-7 (Sunday through Saturday) 
    

    See the demo.

    Update: fixed to work in Swift 3

    Shorter version

    NSCalendarUnit dayOfTheWeek = [[NSCalendar currentCalendar] component:NSCalendarUnitWeekday fromDate:yourDate];

    This is updated version valid for iOS 8

    NSCalendar* currentCalendar = [NSCalendar currentCalendar];
    NSDateComponents* dateComponents = [currentCalendar components:NSWeekdayCalendarUnit fromDate:[NSDate date]];
    return [dateComponents weekday];

    NSCalendar* cal = [NSCalendar currentCalendar];
    NSDateComponents* comp = [cal components:NSCalendarUnitWeekday fromDate:[NSDate date]];
    return [comp weekday]; // 1 = Sunday, 2 = Monday, etc.
    

    See @HuguesBR's answer if you just need the weekday without other components (requires iOS 8+).

    NSInteger weekday = [[NSCalendar currentCalendar] component:NSCalendarUnitWeekday 
                                                       fromDate:[NSDate date]];
    

    (If you don't get a correct answer, check if you have mistyped NSCalendarUnitWeekday with other week-related components like NSCalendarUnitWeekdayOrdinal, etc.)


    Swift 3:

    let weekday = Calendar.current.component(.weekday, from: Date())
    // 1 = Sunday, 2 = Monday, etc.

    let today = Date()
    let day = Calendar.current.dateComponents([.weekday], from: today).weekday
    if ( day == 5)
        {
            yourText.text = "Thursday"
        }
