Stubbing out repeating animations in UI Testing

UITests.swift

import XCTest

class TestCase: XCTestCase {
    let app = XCUIApplication()

    override func setUp() {
        super.setUp()

        continueAfterFailure = false
        app.launchArguments = ["UI-Testing"]
        app.launch()
    }
    
    func testExample() {
        // your tests here
    }
}

View.swift

import UIKit

class Controller: UIViewController {
    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        let options: UIViewAnimationOptions = UITesting() ? .TransitionNone : .Repeat
        UIView.animateWithDuration(2, delay: 0, options: options, animations: { () -> Void in
            // your animations here
        }, completion: nil)
    }

    private func UITesting() -> Bool {
        return NSProcessInfo.processInfo().arguments.contains("UI-TESTING")
    }
}
