If you would like to get exact dateTime as per given/current date (lets say you wanted to convert Monday's dateTime -> 23-05-2016 12:00:00 to 23-05-2016 05:35:17) then try this:

func convertDate(date: NSDate, toGivendate: NSDate) -> NSDate {
    let calendar = NSCalendar.currentCalendar()
    let comp = calendar.components([.Year, .Month, .Day, .Hour, .Minute, .Second], fromDate: toGivendate)
    let hour = comp.hour
    let minute = comp.minute
    let second = comp.second

    let dateComp = calendar.components([.Year, .Month, .Day], fromDate: date)
    let year = dateComp.year
    let month = dateComp.month
    let day = dateComp.day

    let components = NSDateComponents()
    components.year = year
    components.month = month
    components.day = day
    components.hour = hour
    components.minute = minute
    components.second = second

    let newConvertedDate = calendar.dateFromComponents(components)

    return newConvertedDate!
}

simple code (remember to take better care of the optionals):

let now = Date()

var calendar = Calendar(identifier: .gregorian)

let timeZone = TimeZone(identifier: "UTC")!

let desiredWeekDay = 2

let weekDay = calendar.component(.weekday, from: now)
var weekDayDate = calendar.date(bySetting: .weekday, value: desiredWeekDay, of: now)!

/// Swift will give back the closest day matching the value above so we need to manipulate it to be always included at cuurent week.
if weekDayDate > now, weekDay > desiredWeekDay {
    weekDayDate = weekDayDate - 7*24*60*60
}

print(weekDayDate)
