I am getting error" Static method 'buildBlock' requires that 'UInt' conform to 'View'" when trying to read data from Firebase Realtime Database

Question

I simply just want to read the data and store it in an int but I can't seem to read the data of any type without having an error. Please let me know if you need any addition information about the project

Code:

import FirebaseDatabaseSwift
import SwiftUI
import Firebase

struct InGameView: View {
    var ref: DatabaseReference! = Database.database().reference()
    var refOffset: DatabaseReference! = Database.database().reference().child("")
    
    var body: some View {
        

        refOffset.observe(.value) { DataSnapshot in
            print(DataSnapshot)
        }
    }
 }

Answer 1

It has nothing to do with FireBase. refOffset.observe(.value) does not return a view, therefore it shouldn't be used in var body. You may be able to make it compile by changing it to:

var body: some View {

    let _ = refOffset.observe(.value) { DataSnapshot in
        print(DataSnapshot)
    }
}

but don't, that is very poor practice. A call like that should be in its own function, and called from an init() or .onAppear(), or as a result of some state change.
