Can't pass realm data from tableViewController to viewController - ios

Question

I'm having difficulty with passing a realm object's data from a tableViewController to a viewController. I want to choose one of the objects from the table and have that object's data be used in the following viewController. I've struggled to find resources here which deal with Realm objects instead of just passing strings and the likes. Any assistance would be great.
Here's my TableViewController with my attempt at creating a segue function to the second view :
class WorkoutController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return DBHelper.shared.getWorkout().count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
if cell == nil {
cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
}
let muscle = DBHelper.shared.getWorkout()[indexPath.row]
cell.textLabel?.text = muscle
return cell
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let workoutDetailVC = segue.destination as! WorkoutDetail
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let name = DBHelper.shared.getWorkout()[indexPath.row]
workoutDetailVC.receivedName = name
}
}
}
Here's the WorkoutDetail class which is supposed to receive and show the data :
class WorkoutDetail: UIViewController {
#IBOutlet weak var muscleLabel: UILabel!
var receivedName = ""
override func viewDidLoad() {
super.viewDidLoad()
muscleLabel.text = receivedName
}
}
Here is the getWorkout() function referenced above :
func getWorkout()-> [String] {
var musclesName = [String]()
let storedExercise = realm.objects(Workout1.self)
for exercise in storedExercise {
musclesName.append(exercise.exercise)
}
return musclesName
}
I'm having real difficulty with this and would very much appreciate some assistance, thanks.

Get didSelectRowAt out of prepare then
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
if cell == nil {
cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
}
let muscle = DBHelper.shared.getWorkout()[indexPath.row]
cell.textLabel?.text = muscle
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let name = DBHelper.shared.getWorkout()[indexPath.row]
self.performSegue(withIdentifier:"SegueName",sender:name)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let workoutDetailVC = segue.destination as! WorkoutDetail
workoutDetailVC.receivedName = sender as! String
}
