ios - 将日期从怪异的字符串转换为格式为日月和年的日期

Question

嗨，我正在解析API的端点，从那里我得到一个包含这样的日期字符串的字符串 2016-01-18T13:28:06.357 但我想将其转换为 01 Jan 16 ，我已经尝试了通过使用以下提到的不同格式多次。请提出如何完成此任务的建议。

    NSString * date = [dictionary objectForKey:@"date"];
NSDateFormatter *dateformat = [[NSDateFormatter alloc] init];
[dateformat setTimeZone:[NSTimeZone timeZoneWithName:@"EST"]];
[dateformat setDateFormat:@"dd MMM yyyy"];
NSDate *myDate = [dateformat date];

  // Objective C   
        NSString * date = [dictionary objectForKey:@"date"];
        NSDateFormatter *dateformat = [[NSDateFormatter alloc] init];
        [dateformat setTimeZone:[NSTimeZone timeZoneWithName:@"EST"]];
        [dateformat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS"];
        NSDate *myDate = [dateformat dateFromString:date];

        [dateformat setDateFormat:@"dd MMM yyyy"];

        NSString *strDate=[dateformat stringFromDate:myDate];

 // Swift 3.0
       var date = (dictionary["date"] as! String)
       var dateformat = DateFormatter()
       dateformat.timeZone = NSTimeZone(name: "EST")
       dateformat.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSS"
       var myDate = dateformat.date(fromString: date)!

       dateformat.dateFormat = "dd MMM yyyy"
       var strDate = dateformat.string(from: myDate)
