Getting nested children from Firebase Database - ios

Question

I am attempting to populate a table view with values from my Firebase database. I was able to use queryOrdered on the root of my database to get the children I required, as seen here:
func oneTimeInit() {
databaseRef?.queryOrdered(byChild: "Seasons").observe(.value, with:
{ snapshot in
for item in snapshot.children {
self.seasons.append(Season( snapshot: item as! DataSnapshot))
}
self.seasonsTableView.reloadData()
})
}
But now I am trying to get the children of the next node in my database. I tried to do this by calling queryOrdered on the child of the root but I'm not getting any data. Here is my code:
func oneTimeInit() {
databaseRef?.child("Seasons").queryOrdered(byChild: season.name).observe(.value, with:
{ snapshot in
for item in snapshot.children {
print("ITEM VALUE: \(item)")
self.races.append(Race(snapshot: item as! DataSnapshot))
}
self.racesTableView.reloadData()
})
}
The Database contains, at its highest level, Cross Country Seasons, which each contain Cross Country Races, which each contain results. Im able to populate the Seasons table but not the Races table, and so on.
Heres the Json structure of my database:
{
"Seasons" : {
"XC 2018" : {
"NCAA DI West Regional" : {
"Men" : {
"Results" : {
"Aaron BRUMBAUGH" : {
"finishTime" : "31:59.0",
"lapTimes" : [ "5:05.1", "10:43.3", "11:07.1", "5:03.5" ],
"name" : "Aaron BRUMBAUGH",
"position" : "118",
"splitTimes" : [ "5:05.1", "15:48.4", "26:55.5", "31:59.0" ],
"team" : "Santa Clara",
"year" : "SR"
},
"Addison DEHAVEN" : {
"finishTime" : "29:47.8",
"lapTimes" : [ "4:58.2", "10:14.0", "10:04.1", "4:31.5" ],
"name" : "Addison DEHAVEN",
"position" : "7",
"splitTimes" : [ "4:58.2", "15:12.2", "25:16.3", "29:47.8" ],
"team" : "Boise State",
"year" : "SR"
},
"Ahmed MUHUMED" : {
"finishTime" : "30:08.1",
"lapTimes" : [ "4:58.6", "10:14.6", "10:08.5", "4:46.4" ],
"name" : "Ahmed MUHUMED",
"position" : "29",
"splitTimes" : [ "4:58.6", "15:13.2", "25:21.7", "30:08.1" ],
"team" : "Boise State",
"year" : "SO"
},
As of now there is only one "Season" (XC 2018) with one "Race" (NCAA D1 West Regional). I'm trying to get a reference to all of the "Races" under the "Season" XC 2018.
The variable season.name would contain the value "XC 2018". With my second one time init I am trying to look at the children of "XC 2018".
