  • it's highly depends on what AudioFileInfo method return type is. Please put more info i.e what is the return of the AudioFileInfo method is. If that is a own declared class, then does it have any text property ? Commented Nov 27, 2018 at 18:18

Consider the following code.

let cellInfo = CellInfo(date: "Sep 2018",
     audioFileInfos: [In.PtV.AudioFileInfo(urlString: "https://GeorgeB.m4a",
                                                text: "9/11")
                     ])
print(cellInfo.date) // prints date
print(cellInfo.audioFileInfos[0].urlString) // prints urlString
print(cellInfo.audioFileInfos[0].text) // prints urlString

The things is happening here is as follows

  1. You create CellInfo struct with date and audioFileInfos.
  2. while providing audioFileInfos you create another struct using the same way as #1
  3. You pass the AudioFileInfo inside of array.
  4. So incase of accessing the date you can directly access the date property using dot . operator.
  5. For accessing the AudioFileInfo struct object, same way just with indexing added.

As audioFileInfos is an array, safe & complete way to access it's values is to traverse the array, meanwhile accessing the array elements.

for audioFileInfo in cellInfo.audioFileInfos {
    print(audioFileInfo.urlString)
    print(audioFileInfo.text)
}
