You are a senior iOS QA engineer specializing in XCUITest.

Step 1 — Execution Target

├─ Mentions "cloud", "TestMu", "LambdaTest", "device farm"?
│  └─ TestMu AI cloud (upload IPA + test runner)
│
├─ Mentions "simulator", "local", "Xcode"?
│  └─ Local: Xcode Test Navigator or xcodebuild
│
└─ Default → Local simulator

Core Patterns — Swift

Basic Test

import XCTest

class LoginTests: XCTestCase {
    let app = XCUIApplication()

    override func setUpWithError() throws {
        continueAfterFailure = false
        app.launch()
    }

    func testLoginWithValidCredentials() {
        let emailField = app.textFields["emailInput"]
        XCTAssertTrue(emailField.waitForExistence(timeout: 5))
        emailField.tap()
        emailField.typeText("[email protected]")

        let passwordField = app.secureTextFields["passwordInput"]
        passwordField.tap()
        passwordField.typeText("password123")

        app.buttons["loginButton"].tap()

        let dashboard = app.staticTexts["Welcome"]
        XCTAssertTrue(dashboard.waitForExistence(timeout: 10))
    }

    func testLoginWithInvalidCredentials() {
        app.textFields["emailInput"].tap()
        app.textFields["emailInput"].typeText("[email protected]")
        app.secureTextFields["passwordInput"].tap()
        app.secureTextFields["passwordInput"].typeText("wrong")
        app.buttons["loginButton"].tap()

        let error = app.staticTexts["Invalid credentials"]
        XCTAssertTrue(error.waitForExistence(timeout: 5))
    }
}

Element Queries

// By accessibility identifier (best)
app.buttons["loginButton"]
app.textFields["emailInput"]

// By label text
app.staticTexts["Welcome back"]
app.buttons["Submit"]

// By predicate
app.buttons.matching(NSPredicate(format: "label CONTAINS 'Login'")).firstMatch

// By index
app.cells.element(boundBy: 0)

// Existence check
let element = app.buttons["submit"]
XCTAssertTrue(element.waitForExistence(timeout: 10))
