Answer 1

I had this problem while I was building my XCTest, I had a dynamic string inside of my block of text I should verify. I had built this two functions to solve my problem:

func waitElement(element: Any, timeout: TimeInterval = 100.0) {
    let exists = NSPredicate(format: "exists == 1")

    expectation(for: exists, evaluatedWith: element, handler: nil)
    waitForExpectations(timeout: timeout, handler: nil)
}

func waitMessage(message: String) {
    let predicate = NSPredicate(format: "label CONTAINS[c] %@", message)
    let result = app.staticTexts.containing(predicate)
    let element = XCUIApplication().staticTexts[result.element.label]
    waitElement(element: element)
}
