app only updates when i close and re-open it - ios

Question

I am trying to build an IOS app where the user puts options in to a tableview, then the options appear and the spinning frame spins and stops at a random point.
I have put all the necessary code in ViewWillAppear but for some reason the app doesn't update with the user defaults, only when i close the app and re-open it.
It did actually work at one point but then stopped and i have no idea how to fix it. I am using TTFortuneWheel Pod.

I will link my GitHub in case anyone wants to have a look at the full code.

below is the code for the main screen
import UIKit
import TTFortuneWheel
import AVFoundation
class ViewController: UIViewController, UINavigationControllerDelegate {
#IBOutlet weak var spinningWheel: TTFortuneWheel!
#IBOutlet weak var ResultsLabel: UILabel!
let transition = SlideInTransition()
var slices : [CarnivalWheel] = []
var result: String?
var player: AVAudioPlayer!
var soundIsOn = true
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.delegate = self
spinningWheel.initialDrawingOffset = 270.0
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
print("check")
slices = getSlices()
spinningWheel.slices = slices
spinningWheel.equalSlices = true
spinningWheel.frameStroke.width = 0
spinningWheel.titleRotation = CGFloat.pi
spinningWheel.slices.enumerated().forEach { (pair) in
let slice = pair.element as! CarnivalWheel
let offset = pair.offset
switch offset % 6 {
case 0: slice.style = .blue
case 1: slice.style = .green
case 2: slice.style = .grey
case 3: slice.style = .orange
case 4: slice.style = .purple
default: slice.style = .yellow
}
}
}
private func getSlices() -> [CarnivalWheel] {
PersistenceManager.retrieveSlices { [weak self] result in
guard let self = self else {return}
switch result {
case .success(let slices):
if slices.isEmpty {
print("this is where i will add an alert or sumin")
}else {
self.slices = slices
DispatchQueue.main.async {
self.reloadInputViews()
}
}
case .failure(let error):
print("Edit VC Errror ")
}
}
return slices
}

Rather than putting it inside of your viewWillAppear put it inside of the viewDidAppear:
override func viewDidAppear(_ animated: Bool) {
<#code#>
}
