问题
I really need your help guys. The following piece of code works fine in a Swift Playgound and with any iOS8 or 8.1 simulator. But with iOS7 and 7.1, the NSDate object is always set to nil.
The object dateString contains a JSON string (ISO 8601 format) like 2015-02-28T20:15:00+0100 I'm trying to convert this date string into a NSDate object with the following code :
let dateFormatter = NSDateFormatter()
dateFormatter.locale = NSLocale(localeIdentifier: "en_US_POSIX")
dateFormatter.timeZone = NSTimeZone.localTimeZone()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.ZZZ"
if let dateString = (json as NSDictionary).valueForKey("dateAndTime") as? String
{
let dateObject = dateFormatter.dateFromString(dateString)
}
Where's my mistake ? I'm getting confused! Many thanks

The problem is with your time zone offset, your date format is not proper for that. Use the following format,
"yyyy-MM-dd'T'HH:mm:ssZZZZZ"
