Spritekit Печать позиции игрока до и после изменения позиции возвращает одинаковый результат

Question

У меня SKSpriteNode движется вокруг SKTileMapNode. SKSpriteNode перемещается к плитке, к которой прикасается пользователь. В приведенном ниже коде консоль выводит «row: 0, column: 0» до и после перемещения игрока SKSpriteNode. Почему это происходит? Разве второй оператор печати не должен печатать новую позицию игрока?

import SpriteKit
import GameplayKit

class GameScene: SKScene {

var player: SKSpriteNode!
var grid: SKTileMapNode!

var touchLocation: CGPoint = .zero

override func didMove(to view: SKView) {
    self.backgroundColor = .white
    loadSceneNodes()
}

func loadSceneNodes() {
    setupGrid()
    setupCharacter()
}

func setupGrid() {
    let columns = 10
    let rows = 10
    let size = CGSize(width: 64, height: 64)

    guard let tileSet = SKTileSet(named: "Ground Tiles") else {
        fatalError("Tile set not found")
    }

    grid = SKTileMapNode(tileSet: tileSet, columns: columns, rows: rows, tileSize: size)
    addChild(grid)

    grid.name = "grid"

    let tileGroups = tileSet.tileGroups

    guard let dirtLightTile = tileGroups.first(where: {$0.name == "DirtLight Tile"}) else {
        fatalError("No DirtLight tile definition found")
    }

    guard let dirtDarkTile = tileGroups.first(where: {$0.name == "DirtDark Tile"}) else {
        fatalError("No DirtDark tile definition found")
    }

    for column in 0...columns {
        for row in 0...rows {
            if (row % 2 == 0) && (column % 2 == 0) {
                grid.setTileGroup(dirtLightTile, forColumn: column, row: row)
            } else if (row % 2 != 0) && (column % 2 != 0) {
                grid.setTileGroup(dirtLightTile, forColumn: column, row: row)
            } else {
                grid.setTileGroup(dirtDarkTile, forColumn: column, row: row)
            }
        }
    }
}

func setupCharacter() {
    player = SKSpriteNode(imageNamed: "knight")
    let height = player.size.height
    let scaleFactor = grid.tileSize.height / height
    player.setScale(scaleFactor)
    player.position = grid.centerOfTile(atColumn: 0, row: 0)
    addChild(player)
}

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    guard let touch = touches.first else { return }

    touchLocation = touch.location(in: self)

    let touchRow = grid.tileRowIndex(fromPosition: touchLocation)
    let touchCol = grid.tileColumnIndex(fromPosition: touchLocation)

    let touchedNodes = self.nodes(at: touchLocation)
    for node in touchedNodes {
        if node.name == "grid" {

            print(getRowCol(character: player))
            let newTile = grid.centerOfTile(atColumn: touchCol, row: touchRow)
            let move = SKAction.move(to: newTile, duration: 0.5)
            player.run(move)
            print(getRowCol(character: player))
        }
    }
}

func getRowCol(character: SKSpriteNode) -> (row: Int, column: Int) {
        let row = grid.tileRowIndex(fromPosition: character.position)
        let col = grid.tileColumnIndex(fromPosition: character.position)

        return (row, col)

    }
