Please help, I am trying to pass data through a segue using UICollectionViewController
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "eventDetails" {
let vc = segue.destination as! eventDetails
let indexPath = collectionView?.indexPathsForSelectedItems
vc.event = events[indexPath.row]
} else if segue.identifier == "updateevent" {
let vc = segue.destination as! UpdateEventViewController
let indexPath = collectionView?.indexPathsForSelectedItems
vc.event = events[indexPath.row]
}
}My poblem lies on lines 6 and 10
vc.event = events[indexPath.row]Value of type '[indexPath]?' has no member 'row'
Not sure what I should use for item in the collectionView?!
help
As the property name `indexPathsForSelectedItems` represents, the property may return multiple `IndexPath`s, as `UICollectionView` can be configured to allow multiple selection. The type of the property is `[IndexPath]?`, so you need to choose one element from the array to use the result as a single `IndexPath`:
if let indexPath = collectionView?.indexPathsForSelectedItems?.first {
vc.event = events[indexPath.row]
}Assuming you do not allow multiple selection in your `UICollectionView`, always use the first element for your `indexPath`.
