xcode saying "paused app on ipad" and "Thread 1: breakpoint 1.1 (1)"

so my code is:

import UIKit

var rubiksCubeDelegate: RubiksCubeDelegate? = nil

var fromCol: Int = -1

    drawFront()
    drawTop()

    let firstTouch = touches.first!
    let fingerLocation = firstTouch.location(in: self)
    fromCol = Int((fingerLocation.x - originX) / squareSide)
    fromRow = Int((fingerLocation.y - originY) / squareSide)
}

    let fingerLocation = firstTouch.location(in: self)
    let toCol: Int = Int((fingerLocation.x - originX) / 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
