I need to use moveItem(at:to:) delegate method in order to move my collection view cells.
When I implement the data source delegation methods it's working fine, but I need to set my data source as UICollectionViewDiffableDataSource and in this way the moveItem(at:to:) did not call.
Any solution to handle,
This way it's work when using delegations :
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 10
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! CustomCell
cell.textLabel.text = "Some value"
return cell
}
override func collectionView(_ collectionView: UICollectionView, canMoveItemAt indexPath: IndexPath) -> Bool {
true
}
override func collectionView(_ collectionView: UICollectionView, moveItemAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
print("OK")
}
set data source in this way is not work
func setupDataSource() {
dataSource = UICollectionViewDiffableDataSource<Section, Person>(collectionView: collectionView, cellProvider: {
(collectionView: UICollectionView, indexPath: IndexPath, person: Person) -> UICollectionViewCell? in
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! CustomCell
cell.textLabel.text = "Some text"
return cell
})
}
