Can't load in values for tableview cell firebase - ios

Question

I'm trying to load in different values for each cell in a tableview. Currently, I load in a teamID, display it on the current cell, then use that ID to load in the other attributes of the team.
self.ref?.child("Teams").child(currentTeamID).child("Number").observeSingleEvent(of: .value, with: { (snapshot) in
let number1 = snapshot.value as? Int
if let teamNum = number1 {
Cell.teamNumber.text = "team " + String(teamNum)
//breakpoint
}
})
self.ref?.child("Teams").child(currentTeamID).child("memberCount").observeSingleEvent(of: .value, with: { (snapshot) in
let memcon = snapshot.value as? Int
if let membercount = memcon {
Cell.userCount.text = "Members: " + String(membercount)
//breakpoint
}
})
return Cell
My issues comes when trying to load in these other attributes. Should I be doing this is a different way? Right now it loads only the second .observeSingleEvent I have tried placing breakpoint where I indicated above, but only the second one ever gets hit. Do I need a separate reference or is there a way to load all the values from a parent object?
Thanks a whole bunch.
Added Firebase Structure:
ftc-scouting-app
Teams
Brophy Robotics
Name: "Brophy Robotics"
Number: "201"
Password: "bronco"
memberCount: 2
memberList
member1: "5ilQc8KlrERLAmtFXjWaOZLIcoC3"
member2: "syV9SS6S9hY8PyKBOC0VQ3NNv0v2"
Users
5ilQc8KlrERLAmtFXjWaOZLIcoC3
(User Info Values)
syV9SS6S9hY8PyKBOC0VQ3NNv0v2
(User Info Values
The values I'm trying to load are the team number and the member count. I want to put them on the cell as it loads in each team that each user has. So, I just need it to load each value and put it on my custom table view cell that has all the fields for it. To clarify - I already know that it retrieves the team ID properly because it is able to put it on the cell.
The value currentTeamID is a value that I have already loaded in, and is the id (which is the same as the name) of the current cell's prospective team.

Answer 1

First, change the structure
ftc-scouting-app
Teams
Jyis9009kos0kslk //should be generated with childByAutoId()
Name: "Brophy Robotics"
Number: "201"
Password: "bronco"
memberCount: "2"
memberList:
5ilQc8KlrERLAmtFXjWaOZLIcoC3: true //uid as the key
syV9SS6S9hY8PyKBOC0VQ3NNv0v2: true
Users
5ilQc8KlrERLAmtFXjWaOZLIcoC3
(User Info Values)
syV9SS6S9hY8PyKBOC0VQ3NNv0v2
(User Info Values)
Then, let's retrieve just the one team node and get some data
let teamsRef = self.ref.child("ftc-scouting-app").child("Teams")
let thisTeamRef = teamsRef.child("Jyis9009kos0kslk")
thisTeamRef.observeSingleEvent(of: .value, with: { snapshot in
let teamDict = snapshot.value as! [String: AnyObject]
let teamName = teamDict["Name"] as! String
print(teamName)
let memCount = teamDict["memberCount"] as! String
print(memCount)
let memberList = teamDict["memberList"] as! [String: AnyObject]
for user in memberList {
print(user.key)
}
})
and the output is
Brophy Robotics

Answer 2

each event events asynchronously. you should use completion block in your each event.
func getNumber (completion: #escaping (String)->()){self.ref?.child("Teams").child(currentTeamID).child("Number").observeSingleEvent(of: .value, with: { (snapshot) in
let number1 = snapshot.value as? Int
if let teamNum = number1 {
completion(String(teamNum))
}
})}
getNumber(completion: {(teamNum) in
self.ref?.child("Teams").child(currentTeamID).child("memberCount").observeSingleEvent(of: .value, with: { (snapshot) in
let memcon = snapshot.value as? Int
if let membercount = memcon {
Cell.teamNumber.text = "team " + teamNum
Cell.userCount.text = "Members: " + String(membercount)
//breakpoint
}
})
})
