I used the delegate option using UserDefaults to store and load arrays into a table view and it works good but I am trying to use the singleton database option now.
I have everything in my app working right except when I add a player to myRoster or draftOrder it doesn't add the player.
My data:
import Foundation
import UIKit
class PlayerData: Codable {
var num: Int = 0
var name: String = ""
var team: String = ""
var position: String = ""
var strikeThrough: Bool = false
var color: Bool = false
var accessory: Bool = false
var rosterPosition: Int = -1
var draftPosition: Int = -1
init(num: Int, name: String, team: String, position: String) {
self.num = num
self.name = name
self.team = team
self.position = position
}
}
var objectsArray = [PlayerData]()
var myRoster: [PlayerData] = []
var draftOrder: [PlayerData] = []
class Database {
static let shared = Database()

fileprivate func playerDataURL() -> URL {
let documentDirectoryURL = FileManager.default.urls(for: .documentDirectory, in:.userDomainMask).last!

let list = try JSONDecoder().decode([PlayerData].self, from: fileContents)
return list
} catch let error as NSError {
NSLog("Error reading file: \(error.localizedDescription)")

return nil
}

player.rosterPosition = -1 // No longer on the rosterList. Gets all players on roster at a higher index.
let higherNumberedRosterPlayers = allPlayers.filter({ $0.rosterPosition > currentRosterPosition}) // Their rosterPositions have now gone down by one.
for otherPlayer in higherNumberedRosterPlayers {
otherPlayer.rosterPosition -= 1 // Decrease position by 1.
}
