This question was asked about Swift2 but it's still a top search result in 2019 so I wanted to give an up-to-date answer.

With Xcode 9.0+ things are a bit simpler thanks to waitForExistence:

let app = XCUIApplication()
let myButton = app.buttons["My Button"]
XCTAssertTrue(myButton.waitForExistence(timeout: 10))
sleep(1)
myButton.tap()

WebViews Example:

let app = XCUIApplication()
let webViewsQuery = app.webViews
let myButton = webViewsQuery.staticTexts["My Button"]
XCTAssertTrue(myButton.waitForExistence(timeout: 10))
sleep(1)
myButton.tap()
