Combine date and time into a single NSDate in Swift 2.0

combineDateWithTime

    func combineDateWithTime(date: NSDate, time: NSDate) -> NSDate? {
        let calendar = NSCalendar.currentCalendar()
        
        let dateComponents = calendar.components([.Year, .Month, .Day], fromDate: date)
        let timeComponents = calendar.components([.Hour, .Minute, .Second], fromDate: time)

        let mergedComponments = NSDateComponents()
            mergedComponments.year = dateComponents.year
            mergedComponments.month = dateComponents.month
            mergedComponments.day = dateComponents.day
            mergedComponments.hour = timeComponents.hour
            mergedComponments.minute = timeComponents.minute
            mergedComponments.second = timeComponents.second
    
        return calendar.dateFromComponents(mergedComponments)
    }

Thanks for posting this. It was a big help.

Thank you

Swift 3 version

func combineDateWithTime(date: Date, time: Date) -> Date? {
    let calendar = NSCalendar.current
    
    let dateComponents = calendar.dateComponents([.year, .month, .day], from: date)
    let timeComponents = calendar.dateComponents([.hour, .minute, .second], from: time)

    var mergedComponments = DateComponents()
    mergedComponments.year = dateComponents.year!
    mergedComponments.month = dateComponents.month!
    mergedComponments.day = dateComponents.day!
    mergedComponments.hour = timeComponents.hour!
    mergedComponments.minute = timeComponents.minute!
    mergedComponments.second = timeComponents.second!
    
    return calendar.date(from: mergedComponments)
}

Thanks. Save a lot of my time :) 👍

Searched for this piece of code for days. Thanks m8

Thankyou Saved my Day. :) 👍

Thanks! How should we create the properties for date and time?

Worked!!! 👍 💯

After multiple year it still is a very nice solution. Thanks

Swift 5 version, typo fixed and without force unwrapping:

func combineDateWithTime(date: Date, time: Date) -> Date? {
        let calendar = NSCalendar.current
        
        let dateComponents = calendar.dateComponents([.year, .month, .day], from: date)
        let timeComponents = calendar.dateComponents([.hour, .minute, .second], from: time)
        
        var mergedComponents = DateComponents()
        mergedComponents.year = dateComponents.year
        mergedComponents.month = dateComponents.month
        mergedComponents.day = dateComponents.day
        mergedComponents.hour = timeComponents.hour
        mergedComponents.minute = timeComponents.minute
        mergedComponents.second = timeComponents.second
        
        return calendar.date(from: mergedComponents)
    }

Genius! Thanks so much, you saved so much time for all of us!
