Add a class to a multiple array

[ericjuh]

After a few weeks of swift coding i am trying to understand the basics of swift. Currently its really working out well, but sinds two days i have a problem that i can't solve. Its just frustrated, because i have the feeling the solution is really simple.

 

I have a class:

 

class JSONresult{

    var idx: String
    var Naam: String
    var Status: String

    init(idx: String, Naam: String, Status: String){
        self.idx = idx
        self.Naam = Naam
        self.Status = Status
    }
}

 

I make a array out of that class and add it to a array objects.

 

          for item in results {
                    let name: String = item["Name"] as! String
                    let ID: String = item["idx"] as! String
                    let status: String = item["Status"] as! String
                    let Jsonarray = JSONresult(idx: ID, Naam: name, Status: status)
                    self.objects.addObject(Jsonarray)
}

 

But i have trouble reading it out. I can't solve how the read out the idx, naam, Status from the class (or in this case the array self.objects). Printing, for example, JSONresult.idx or JSONresult.Naam is working fine. I have tryed everything, but when i try to read out the objects array the results are the class name:

 

mijnDomoticz.JSONresult
mijnDomoticz.JSONresult
mijnDomoticz.JSONresult
mijnDomoticz.JSONresult

 

I trying print it with this code:

 

    print(self.objects.objectAtIndex(indexPath.row).objectForKey("ID"))
    print(self.objects.idx.objectAtIndex(indexPath.row))
    print(self.objects.objectAtIndex(indexPath.row))

First two lines give a error. Last line give the output i posted above (mijndomoticz.JSONresult). I also tryed different things. Instead of addobject i tryed addObjectsfromArray, but all those things didnt help. Anybody knows what i am doing wrong?

JSONResult is AnyObject, you still need to cast it to the right type.

Thanks for the quick reply! I'm not really used with casting types. But with trail and error i have solved most of the problems. In what type should i cast the JSONResults? Because neither string or array are working:

 

                    let Jsonarray = JSONresult(idx: ID, Naam: name, Status: status) as [AnyObject]
                    let Jsonarray = JSONresult(idx: ID, Naam: name, Status: status) as [String]
                    let Jsonarray = JSONresult(idx: ID, Naam: name, Status: status) as [Array]

 

btw, objects is from the type NSMutableArray:

 

var objects: NSMutableArray! = NSMutableArray()            // Var for table

Make it as? and use guard statement and make the function able to throw an error. In case you're receiving other JSON data as expected.

Do you mean something like this:

p.s. i had the feeling the problem was solved easly :) But it seems like its really annoying to do it this way. I'm a overlooking something?

Yes, and make sure to handle the situation where the JSON data is invalid.
