Setting up in UITest file

import XCTest

class StackOverFlowUITests: XCTestCase {

    private let app = XCUIApplication()

    //Views

    private var view: XCUIElement!

    //Buttons

    private var addButton: XCUIElement!


    override func setUp() {
        super.setUp()
    
        app.launch()
    
        //Views
    
        view = app.otherElements["view"]
    
        //Buttons
    
        addButton = app.buttons["addButton"]
    }

    func testMyApp() {

        addButton.tap()
        view.tap()
    }    
}

In [ ] add Accessibility Identifier for element.

    app.launch()
}

Terminating application

func testStacOverFlowApp() {
    
    app.terminate()
}

Rotate devices

Device can be rotate by changing orientation in XCUIDevice.shared().orientation:

XCUIDevice.shared().orientation = .landscapeLeft
XCUIDevice.shared().orientation = .portrait
