Can't move UITableView Rows Swift 4

Question

this code was fully working prior updating to ios 11 and swift 4, I don't know what's happening I have also attached a video showing the issue.

I can't move the rows anymore. Any advise? Thanks.

override func tableView(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool {
    return true
}

//Do the Move action
override func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {

    let moveMainArray:String = mainArrayTableName[sourceIndexPath.row]
    mainArrayTableName.remove(at: sourceIndexPath.row)
    mainArrayTableName.insert(moveMainArray, at: destinationIndexPath.row)
    print(mainArrayTableName[destinationIndexPath.row])

    let moveFirstName:String = firstName[sourceIndexPath.row]
    firstName.remove(at: sourceIndexPath.row)
    firstName.insert(moveFirstName, at: destinationIndexPath.row)
    print(firstName[destinationIndexPath.row])

    let moveLastName:String = lastName[sourceIndexPath.row]
    lastName.remove(at: sourceIndexPath.row)
    lastName.insert(moveLastName, at: destinationIndexPath.row)
    print(lastName[destinationIndexPath.row])

    let moveTotalAmount:String = totalAmount[sourceIndexPath.row]
    totalAmount.remove(at: sourceIndexPath.row)
    totalAmount.insert(moveTotalAmount, at: destinationIndexPath.row)
    print(totalAmount[destinationIndexPath.row])

    let moveLastAmount:String = lastAmount[sourceIndexPath.row]
    lastAmount.remove(at: sourceIndexPath.row)
    lastAmount.insert(moveLastAmount, at: destinationIndexPath.row)
    print(lastAmount[destinationIndexPath.row])

    let moveAddress:String = address[sourceIndexPath.row]
    address.remove(at: sourceIndexPath.row)
    address.insert(moveAddress, at: destinationIndexPath.row)
    print(address[destinationIndexPath.row])

    let movePhoneNbr:String = phoneNbr[sourceIndexPath.row]
    phoneNbr.remove(at: sourceIndexPath.row)
    phoneNbr.insert(movePhoneNbr, at: destinationIndexPath.row)
    print(phoneNbr[destinationIndexPath.row])

    let moveLastPayment:String = lastPaymentDate[sourceIndexPath.row]
    lastPaymentDate.remove(at: sourceIndexPath.row)
    lastPaymentDate.insert(moveLastPayment, at: destinationIndexPath.row)
    print(lastPaymentDate[destinationIndexPath.row])

    let moveNextPayment:String = nextPaymentDate[sourceIndexPath.row]
    nextPaymentDate.remove(at: sourceIndexPath.row)
    nextPaymentDate.insert(moveNextPayment, at: destinationIndexPath.row)
    print(nextPaymentDate[destinationIndexPath.row])

    let moveRemaining:String = remainingAmount[sourceIndexPath.row]
    remainingAmount.remove(at: sourceIndexPath.row)
    remainingAmount.insert(moveRemaining, at: destinationIndexPath.row)
    print(remainingAmount[destinationIndexPath.row])

    print(userID[destinationIndexPath.row])  
}

Try tableView.setEditing(true, animated: true). It will give you both (reorder and delete) controls as given in image.

I will try this, but the issue is that i'm having the edit and delete icons. You can check the video link I have attached. The Issue is that the rows are not moving. – Khajak Kirikian Apr 11 '18 at 20:15
I have added that line of code under: override func tableView(_ tableView: UITableView, canMoveRowAt: indexPath: IndexPath) -> Bool { } --------But no luck-------- – Khajak Kirikian Apr 12 '18 at 05:41
Are you getting callback in `tableView(_ tableView: UITableView, canMoveRowAt: indexPath: IndexPath)` ? In my case when I add `tableView.isEditing = true` in `viewDidLoad()` It worked. – Chanchal Chauhan Apr 12 '18 at 06:12
Were you facing the same issue? And yes it's going through that Method, I have even removed the above code and kept: let moveMainArray:String = mainArrayTableName[sourceIndexPath.row] mainArrayTableName.remove(at: sourceIndexPath.row) mainArrayTableName.insert(moveMainArray, at: destinationIndexPath.row) print(mainArrayTableName[destinationIndexPath.row]) But still nothing. I will try to add tableView.isEditing = true in ViewDidLoad() and update you. Thanks! – Khajak Kirikian Apr 12 '18 at 15:02
The tableView.isEditing = true, will only activate the edit mode on launch. Tested. But my issue still there, it's like the rows are locked and I can't move them. So Weird – Khajak Kirikian Apr 16 '18 at 01:17
Can you share your code. Because in my case its moving perfectly. – Chanchal Chauhan Apr 16 '18 at 05:36
Well The code is still the above, no changes I have removed the UINavigationController View, and it worked good. – Khajak Kirikian Apr 22 '18 at 21:55

If by any chance you have this in your code:

navigationController?.hidesBarsOnSwipe = true

Then set it to false, to give priority to tableview's scrollview.

The issue is due to the Navigation Controller "hide bars" "on swipe" option. If you deselect it, the issue is fixed.

The Issue isn't in the code itself. For some reason, I had a navigation Controller and that was causing the issue. Once that's removed, the re-ordering is now working perfect with no issues. Thanks for the help.
