You can create an extensions to simply use it over XCUIElement.

extension XCUIElement {
    
    func assertContains(text: String) {
        let predicate = NSPredicate(format: "label CONTAINS[c] %@", text)
        let elementQuery = staticTexts.containing(predicate)
        XCTAssertTrue(elementQuery.count > 0)
    }
}

Usage:

// Find the label
let yourLabel = app.staticTexts["AccessibilityIdentifierOfYourLabel"].firstMatch

// assert that contains value
yourLabel.assertContains(text: "a part of content of the staticText")
