3. Wait
4. Wait 4 let app = XCUIApplication() let button = app.buttons.firstMatch button.tap()
5. Wait 5 let app = XCUIApplication() let button = app.buttons.firstMatch button.tap() ❌
6. Wait 6 let app = XCUIApplication() let button = app.buttons.firstMatch button.tap() ❌ ❌
7. Wait 7 let app = XCUIApplication() let button = app.buttons.firstMatch button.tap() ✅
8. Fix
9. Wait 9 let app = XCUIApplication() let button = app.buttons.firstMatch let predicate = NSPredicate( format: "exists == true && hittable == true" ) let ex = XCTNSPredicateExpectation( predicate: predicate, object: button ) XCTWaiter.wait( for: [ex], timeout: 10 ) button.tap() ⏰ wait…
10. Wait 10 let app = XCUIApplication() let button = app.buttons.firstMatch let predicate = NSPredicate( format: "exists == true && hittable == true" ) let ex = XCTNSPredicateExpectation( predicate: predicate, object: button ) XCTWaiter.wait( for: [ex], timeout: 10 ) button.tap() ⏰ wait…
11. Wait 11 let app = XCUIApplication() let button = app.buttons.firstMatch let predicate = NSPredicate( format: "exists == true && hittable == true" ) let ex = XCTNSPredicateExpectation( predicate: predicate, object: button ) XCTWaiter.wait( for: [ex], timeout: 10 ) button.tap() ✅ completed! ✅
12. Wait 12 let predicate = NSPredicate { object, _ in guard let element = object as? XCUIElement else { return false } return element.exists && element.isHittable } let ex = XCTNSPredicateExpectation( predicate: predicate, object: button ) XCTWaiter.wait( for: [ex], timeout: 10 ) button.tap() ✅ completed! ✅
13. Scroll
14. Scroll 14
15. Scroll 15
16. Scroll 16
17. Scroll 17 scrollView.swipeLeft(velocity: .slow)
18. Scroll 18 scrollView.swipeLeft(velocity: .slow) ⚠
19. Fix
20. let start = scrollView.coordinate(withNormalizedOffset: CGVector(dx: 0.5, dy: 0.5)) let end = start.withOffset(CGVector(dx: -350, dy: 0)) start.press( forDuration: 0.02, thenDragTo: end, withVelocity: 250, thenHoldForDuration: 0.07 ) Scroll 20 ☝
