I don\'t see a good way to create an expectation for this and wait using

Answer 1

Based on onmyway133 code I came up with to extensions (Swift 3.2):

extension XCTestCase {
  func wait(for element: XCUIElement, timeout: TimeInterval) {
    let p = NSPredicate(format: "exists == true")
    let e = expectation(for: p, evaluatedWith: element, handler: nil)
    wait(for: [e], timeout: timeout)
  }
}

extension XCUIApplication {
  func getElement(withIdentifier identifier: String) -> XCUIElement {
    return otherElements[identifier]
  }
}

So on your call site you can use:

wait(for: app.getElement(withIdentifier: "ViewController"), timeout: 10)
