so my code is:

let firstTouch = touches.first!
let fingerLocation = firstTouch.location(in: self)
fromCol = Int((fingerLocation.x - originX) / squareSide)
fromRow = Int((fingerLocation.y - originY) / squareSide)
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
let firstTouch = touches.first!
let fingerLocation = firstTouch.location(in: self)
let toCol: Int = Int((fingerLocation.x - originX) / squareSide)
let toRow: Int = Int((fingerLocation.y - originY) / squareSide)
print("V: from (\(fromCol), \(fromRow) to (\(toCol), \(toRow))")
rubiksCubeDelegate?.moveFinger(fromCol: fromCol, fromRow: fromRow, toCol: toCol, toRow: toRow)

at "func drawFront() {" it said "Thread 1: breakpoint 1.1 (1)"
can any one help me fix this the app is always pausing
