I have a comboBox in my cocoa app. I need it to display all of the string data inside the realm file. Each string is a name. Currently only the last entered name will display and I cant find the code to display all names.
ComboBox
name1
name2
name3
name4
etc.
here is the code
@IBOutlet weak var comboBox: NSComboBox!
var realm : Realm?
var theData : Results<NewData>?
override func viewDidLoad() {
super.viewDidLoad()
let config = SyncUser.current!.configuration(realmURL: Constants.REALM_URL, fullSynchronization: true, enableSSLValidation: true, urlPrefix: nil)
self.realm = try! Realm(configuration: config)
comboBox.reloadData()
comboBox.usesDataSource = true
comboBox.dataSource = self
}
extension PublisherViewController: NSComboBoxDataSource {
func numberOfItems(in comboBox: NSComboBox) -> Int {
return theData?.count ?? 0
}
func comboBox(_ comboBox: NSComboBox, objectValueForItemAt index: Int) -> Any? {
comboBox.stringValue = (theData?.last?.addName) ?? ""
return true
}
}

Well, right off the bat, if you're trying to use theData as your dataSource, it's empty so nothing would be displayed. You need to write the code to populate that array/Realm results from Realm. Second thing is the objectForValueAt is passed an int so you know which item in the array you need to return but it's unused and you're returning true, where it should be... a string.. and your setting the stringValue of the comboBox to the last element of the array each time. Take a look at the NSComboBox and datasource documentation.

So I have it working and I have tried to figure out returning all strings from a property in the realmFile with no success. all I can return is either the first string or the last string. return theData?.last?.addName or return theData?.first?.addName

The comboBox datasource is typically an array of objects. It could be strings, ints or something else. Looking at the NSComboBox docs, you'll see that the function func comboBox(_ comboBox: NSComboBox, objectValueForItemAt index: Int) is passed an index Int of the item for it to display. for example when the box opens it's menu, that function is passed 0, then 1, then 2 then 3 etc. Those are the indexes of what's stored in the array. In this case you can use your Realm Results object (theData) as it behaves like an array. So you would need to return theData[index] in that function, not true.

The problem is that when I return theData[index] I get this error [General] -[RLM:Managed 4 NewData copyWithZone:]: unrecognized selector sent to instance 0x600002626820

That's because it needs to populate the Menu with strings. I slightly mis-spoke in my above comment. You would need to get your Realm object, get the string you want from it - like a name or email address and return that string. Again, the docs cover that, and there are a number of examples here on SO on how to populate that menu.
