So I'm just learning the basics of Swift. I have a table view of items and when an item is clicked I want to show a view that displays the details of that specific item. I have the below code in which I'm trying to achieve this, although, I'm getting a Bad Instruction runtime error. Any idea where I'm going wrong? Thanks!
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
super.prepare(for: segue,sender: sender)
switch(segue.identifier ?? "") {
//the add item button is pressed
case "AddItem":
os_log("Adding a new donation.", log: OSLog.default, type: .debug)
//an existing item is pressed
case "ShowDetailDrill":
guard let itemViewController = segue.destination as? ItemViewController else {
fatalError("Unexpected destination: \(segue.destination)")
}
guard let selectedDonationItemCell = sender as? DonationItemCell else {
fatalError("Unexpected sender: \(sender)")
}
guard let indexPath = tableView.indexPath(for: selectedDonationItemCell) else {
fatalError("The selected cell is not being displayed by the table")
}
let selectedDonation = donatedItems.getItem(index: indexPath.row)
//TODO: load this to SubmissionVC
itemViewController.donatedItem = selectedDonation
default:
fatalError("Unexpected Segue Identifier; \(segue.identifier)")
}
}
Update
I forgot to mention that it breaks here
Update 2: Ok so I removed the navigation controller and changed the segue from a "present modally" to "show". It goes directly from the cell to the item controller. Everything now works, although I'm still somewhat confused on why it wasn't working with the navigation controller. If someone is able to explain the why, I'll mark that as the answer.
