如何在XCUITest里使用位置定位element

func tapCoordinate(at point: CGPoint) {
        let normalized = coordinate(withNormalizedOffset: .zero)
        let offset = CGVector(dx: point.x, dy: point.y)
        let coordinate = normalized.withOffset(offset)
        coordinate.tap()
    }

let app = XCUIApplication()
app.launch()
sleep(5)

let point = CGPoint(x: 328.0, y: 392.0)
app.tapCoordinate(at: point)
