XCUITest Reference

Comprehensive reference for writing reliable XCUITest UI tests in Swift 6.

Quick Reference

// Basic test structure
@MainActor
final class MyUITests: XCTestCase {
    var app: XCUIApplication!

    override func setUp() {
        super.setUp()
        continueAfterFailure = false
        app = XCUIApplication()
        app.launch()
    }

    func testExample() {
        let button = app.buttons["Submit"]
        XCTAssertTrue(button.waitForExistence(timeout: 5))
        button.tap()
    }
}

Fetching More Apple Docs

1. Search this skill's local .md files first.
2. If the topic is not here, check the other installed Apple skills you have available by their names, descriptions, or SKILL.md frontmatter, then grep their local files. This is faster and uses less context than fetching new docs from the internet.
3. If no installed skill has the page, use the relevant documentation path from the local XCTest or XCUIAutomation indexes with the sosumi.ai Markdown mirror. For example, /documentation/xcuiautomation/xcuielement maps to https://sosumi.ai/documentation/xcuiautomation/xcuielement.
