1:28 - New supportsPointerInteraction property on XCUIDevice

extension XCUIDevice {

  public var supportsPointerInteraction: Bool

}

1:37 - New methods on XCUIElement and XCUICoordinate for pointer interactions on iOS

extension XCUIElement {
  open func hover()

  open func click()

  open func rightClick()

  open func doubleClick()

  open func scroll(byDeltaX: CGFloat, deltaY: CGFloat)

  open func click(forDuration: TimeInterval, thenDragToElement: XCUIElement)

  open func click(forDuration: TimeInterval, thenDragToElement: XCUIElement,
                  withVelocity: XCUIGestureVelocity, thenHoldForDuration: TimeInterval)

  open class func perform(withKeyModifiers flags: XCUIElement.KeyModifiers,
                          block: () -> Void)
}

2:31 - Empty UI test class

import XCTest

class Pointer_UI_Tests: XCTestCase {



}

2:43 - UI test for opening the sidebar with a two-finger horizontal trackpad swipe

import XCTest

class Pointer_UI_Tests: XCTestCase {

  @available(iOS 15.0, *)
  func testHorizontalScrollRevealsSidebar() throws {
    let app = XCUIApplication()
    app.launch()

    let sidebar = app.tables["Sidebar"]

    // Make sure sidebar menu is not present initially.
    XCTAssertFalse(sidebar.exists, "Sidebar should not be present initially")

    // Swipe horizontally to reveal sidebar.
    app.staticTexts["Select a smoothie"].scroll(byDeltaX: -200, deltaY: 0)

    // Verify sidebar is now present.
    XCTAssertTrue(sidebar.waitForExistence(timeout: 5),
                  "Sidebar did not appear within 5 second timeout")
  }

}

4:36 - Use the new supportsPointerInteraction property to skip the test on devices that don't support pointer interaction

import XCTest

class Pointer_UI_Tests: XCTestCase {

  @available(iOS 15.0, *)
  func testHorizontalScrollRevealsSidebar() throws {
    try XCTSkipUnless(XCUIDevice.shared.supportsPointerInteraction,
                      "Device does not support pointer interaction")

    let app = XCUIApplication()
    app.launch()

    let sidebar = app.tables["Sidebar"]

    // Make sure sidebar menu is not present initially.
    XCTAssertFalse(sidebar.exists, "Sidebar should not be present initially")

    // Swipe horizontally to reveal sidebar.
    app.staticTexts["Select a smoothie"].scroll(byDeltaX: -200, deltaY: 0)

    // Verify sidebar is now present.
    XCTAssertTrue(sidebar.waitForExistence(timeout: 5),
                  "Sidebar did not appear within 5 second timeout")
  }

}

5:27 - New method on XCUIDevice for Digital Crown rotation on watchOS

// New rotateDigitalCrown API

extension XCUIDevice {

  open func rotateDigitalCrown(delta: CGFloat, velocity: XCUIGestureVelocity = .default)

}

6:22 - UI test to verify the app's Digital Crown rotation functionality behaves as expected

// Example use of watchOS Digital Crown API

func testForecastScrolling() {
  let app = XCUIApplication()
  app.launch()

  let forecastTime = app.staticTexts["forecast-time"]

  XCTAssertEqual(forecastTime.label, "Current Temperature")

  // Scroll 1 full rotation forward.
  XCUIDevice.shared.rotateDigitalCrown(delta: 1.0)
  XCTAssertEqual(forecastTime.label, "One hour from now")

  // Scroll 2 full rotations backward.
  XCUIDevice.shared.rotateDigitalCrown(delta: -2.0)
  XCTAssertEqual(forecastTime.label, "One hour ago")
}

7:46 - Existing API for performing discrete (mouse wheel-like) scrolling on macOS

extension XCUIElement {

  // Use the existing API for discrete (mouse wheel-like) scrolling.
  open func scroll(byDeltaX: CGFloat, deltaY: CGFloat)

}

8:05 - New API for performing continuous (trackpad-like) scrolling on macOS

extension XCUIElement {

  // Use the new API for continuous (trackpad-like) scrolling.
  open func swipeUp(velocity: XCUIGestureVelocity = .default)
  open func swipeDown(velocity: XCUIGestureVelocity = .default)
  open func swipeLeft(velocity: XCUIGestureVelocity = .default)
  open func swipeRight(velocity: XCUIGestureVelocity = .default)
