Helper methods to open ControlCenter and NotificationCenter from Xcode UITests

XCTestCase+UITestUtils.swift

import XCTest

extension XCTestCase {
    var springboard: XCUIApplication {
        return XCUIApplication(bundleIdentifier: "com.apple.springboard")
    }
    
    func closeApp() {
        XCUIDevice.shared.press(XCUIDevice.Button.home)
    }
    
    func openNotificationCenter(from app: XCUIApplication) {
        let coord1 = app.coordinate(withNormalizedOffset: CGVector(dx: 0.1, dy: 0.01))
        let coord2 = app.coordinate(withNormalizedOffset: CGVector(dx: 0.1, dy: 0.8))
        coord1.press(forDuration: 0.1, thenDragTo: coord2)
    }
    
    func openControlCenter(from app: XCUIApplication) {
        let coord1 = app.coordinate(withNormalizedOffset: CGVector(dx: 0.9, dy: 0.01))
        let coord2 = app.coordinate(withNormalizedOffset: CGVector(dx: 0.9, dy: 0.2))
        coord1.press(forDuration: 0.1, thenDragTo: coord2)
    }
    
}

Inside your UITest functions you can now for example do the following:

To open ControlCenter from your app you can now simply call:

openControlCenter(from: XCUIApplication())

To close your app and open NotificationCenter from the Springboard you can call:

closeApp()
openNotificationCenter(from: springboard)
