Unexpectedly found nil while unwrapping an Optional value from XIB file - ios

Error: Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value
Hello everyone, I'm making an app that functions like a "To-Do List" app. However I've made two XIBs for my two custom cells that I want displayed on my TableView.
Keep in mind this is my first time using XIBs and building something that's not been a follow along. I've watched many "To-Do List" projects to get an idea of how this should work so I feel as if I'm on the right path. Anyways, to the code.
My prepare for segue func that is giving the error after putting text into the box :
var card: Card?
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
super.prepare(for: segue, sender: sender)
guard segue.identifier == "saveUnwind" else { return }
let taskText = card!.taskCell.taskText.text
let taskBtn = card!.taskCell.taskBtn.isSelected
let gratefulText = card!.gratefulCell.gratefulText.text
let gratefulNum = card!.gratefulCell.gratefulNum.text
card = Card(taskText: taskText!, taskBtn: taskBtn, gratefulText: gratefulText!, gratefulNum: gratefulNum!)
}
Here is my "Card" struct:
struct Card: Equatable {
let gratefulCell = GratefulCell()
let taskCell = TaskCell()
var id = UUID()
var taskText: String
var taskBtn: Bool
var gratefulText: String
var gratefulNum: String
static let dueDateFormatter: DateFormatter = {
let formatter = DateFormatter()
formatter.dateStyle = .short
formatter.timeStyle = .short
return formatter
}()
static func ==(lhs: Card, rhs: Card) -> Bool {
return lhs.id == rhs.id
}
static func loadTasks() -> [Card]? {
return nil
}
static func loadSampleTasks() -> [Card]? {
let task1 = Card(taskText: "Test", taskBtn: false, gratefulText: "Test", gratefulNum: "1")
let task2 = Card(taskText: "Test2", taskBtn: false, gratefulText: "Test2", gratefulNum: "2")
return [task1, task2]
}
}
Also here is the XIB file in which I'm trying to access the .text on:
class TaskCell: UITableViewCell {
#IBOutlet weak var taskBtn: UIButton!
#IBOutlet weak var taskText: UITextField!
override func awakeFromNib() {
super.awakeFromNib()
// updateSaveButtonState()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
#IBAction func textEditingChanged(_ sender: UITextField) {
// updateSaveButtonState()
}
#IBAction func isCompleteButtonTapped(_ sender: UIButton) {
taskBtn.isSelected.toggle()
}
}
If there's any other information I can provide please let me know! Any advice is greatly appreciated.
