How sort json array multiple times in swift - mysql

Question

I am trying to sort an array by a few values, not just one but three I can sort it like this
mysocialArray.sort({$0["date"] > $1["date"]})
This works fine, but i can find any where how to then sort it again so i get them sorted on time and another sort. SO should sort three times. When i just add another sort it is not taking the date into account.
The sorted json output will then be loaded in arrays as strings to display on the viewcontroller
How should I solve this?
thanks

Given your requirements of "This way the latest post that not yet have been read are at the top", looks like you are looking to sort by multiple criteria. I typed this in the dark so you may have to adjust it to fit your case:
mySocialArray.sort {
// First sort by read status. Assuming read is of type Bool
let (read1, read2) = ($0["read"] ? 1 : 0, $1["read"] ? 1 : 0)
if read1 != read2 {
return read1 > read2
}
// Then short by date. I assume date is of type NSDate
let (date1, date2) = ($0["date"], $1["date"])
if date1.timeIntervalSince1970 != date2.timeIntervalSince1970 {
return date1 > date2
}
// And lastly sort by time
return $0["time"] > $1["time"]
}
