使用Swift 4&斯威夫特3

let testArray = ["25 Jun, 2016", "30 Jun, 2016", "28 Jun, 2016", "2 Jul, 2016"]
var convertedArray: [Date] = []

var dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd MM, yyyy"// yyyy-MM-dd"

for dat in testArray {
    let date = dateFormatter.date(from: dat)
    if let date = date {
        convertedArray.append(date)
    }
}

var ready = convertedArray.sorted(by: { $0.compare($1) == .orderedDescending })

print(ready)

使用Swift 2

例如，您有一个包含日期的数组和另一个1数组，您将在其中保存转换后的日期:

For example you have the array with dates and another 1 array, where you will save the converted dates:

var testArray = ["25 Jun, 2016", "30 Jun, 2016", "28 Jun, 2016", "2 Jul, 2016"]
var convertedArray: [NSDate] = []

之后，我们转换日期:

var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd MM, yyyy"// yyyy-MM-dd"

for dat in testArray {
    var date = dateFormatter.dateFromString(dat)
    convertedArray.append(date!)
}

结果:

var ready = convertedArray.sort({ $0.compare($1) == .OrderedDescending })

print(ready)
