nsdate

I really don't get what is happening with this code, I'm trying to convert a string to date. What I don't understand is that the conversion works for most of the dates, but doesn't work specially for only 2 dates. let dateFormatter = NSDateFormatter() dateFormatter.locale = NSLocale(localeIdentifier: "es") dateFormatter.dateFormat = "dd 'de' MMMM" dateFormatter.dateFromString("1 de octubre") dateFormatter.dateFromString("2 de octubre") dateFormatter.dateFromString("3 de octubre") dateFormatter.dateFromString("4 de octubre") dateFormatter.dateFromString("5 de octubre") dateFormatter

I am trying to make a stop watch with NSTimer. I gave the following code: nst_Timer = [NSTimer scheduledTimerWithTimeInterval:0.001 target:self selector:@selector(showTime) userInfo:nil repeats:NO]; and it is not working in milliseconds. It takes more than 1 millisecond. Don't use NSTimer that way. NSTimer is normally used to fire a selector at some time interval. It isn't high precision and isn't suited to what you want to do. What you want is a High resolution timer class (using NSDate ): Output: Total time was: 0.002027 milliseconds Total time was: 0.000002 seconds Total time was: 0.000000

In a swift playground, I have been using NSDate.date() But, this always appears with the time element appended. For my app I need to ignore the time element. Is this possible in Swift? How can it be done? Even if I could set the time element to be the same time on every date that would work too. Also, I am trying to compare two dates and at the moment I am using the following code: var earlierDate:NSDate = firstDate.earlierDate(secondDate) Is this the only way or can I do this in a way that ignores the time element? For instance I don't want a result if they are the same day, but different

I created a method that is supposed to take in a string in "YYYY-MM-DD" form and spit out an int that represents the dates position in relation to the week it is in (regardless if it overlaps between months). So e.g sunday=1 monday=2 and so on. Here is my code: func getDayOfWeek(today:String)->Int{ var formatter:NSDateFormatter = NSDateFormatter() formatter.dateFormat = "YYYY-MM-DD" var todayDate:NSDate = formatter.dateFromString(today)! var myCalendar:NSCalendar = NSCalendar(calendarIdentifier: NSGregorianCalendar) var myComponents = myCalendar.components(NSCalendarUnit

How can we measure the time elapsed for running a function in Swift? I am trying to display the elapsed time like this: "Elapsed time is .05 seconds". Saw that in Java , we can use System.nanoTime(), is there any equivalent methods are available in Swift to accomplish this? Please have a look at the sample program: func isPrime(var number:Int) ->Bool { var i = 0; for i=2; i<number; i++ { if(number % i == 0 && i != 0) { return false; } } return true; } var number = 5915587277; if(isPrime(number)) { println("Prime number"); } else { println("NOT a prime number"); } JeremyP Here's a Swift

I have a Core Data model with an NSDate property. I want to filter the database by day. I assume the solution will involve an NSPredicate , but I'm not sure how to put it all together. I know how to compare the day of two NSDate s using NSDateComponents and NSCalendar , but how do I filter it with an NSPredicate ? Perhaps I need to create a category on my NSManagedObject subclass that can return a bare date with just the year, month and day. Then I could compare that in an NSPredicate . Is this your recommendation, or is there something simpler? Given a NSDate * startDate and endDate and a
