Here is auto generated code. I didn't modified it.
func testExample() {
let app = XCUIApplication()
let defaultStaticText = app.tables.staticTexts["Default"]
defaultStaticText.tap()
}
Error I got is:
UI Test Activity:
Assertion Failure: UI Testing Failure - Failure getting list of active applications: AX error -25205
Screenshot of the app:
All I did during the test is tapping on the Default row on top. I did this in Simulator. The error appears on the last line: defaultStaticText.tap().
Have you tried to use completely different names for “Default” and “Default configured”?
I think you get multiple cells for
let defaultStaticText = app.tables.staticTexts["Default"]

Xcode UI Testing takes automatic screenshots for viewing in the results navigator whenever a test fails, which is greatly helpful. However, that does not include tests that fail because a predicate is failed. Since predicates are often for basic checks (such as if an element exists or not on a current view), that is a huge drawback because a screenshot would be useful in diagnosing what was happening in the app when the test failed.
Does anyone know how to force a screenshot? Does this require integrating the Fastlane Snapshot tool?
On tearDown you can check if test failed (that's helpful if you are not discarding screenshots when tests pass.)
if let failureCount = testRun?.failureCount, failureCount > 0 {
takeScreenshot()
}
If you are using Xcode 9 already, the takeScreenshot function can use the new API (If not, then use the workaround mentioned by the other answer) :
let screenshot = XCUIScreen.main.screenshot()
let attach = XCTAttachment(screenshot: screenshot)
add(attach)
You can also name the attach and change its lifetime ;)
See Apple's documentation for how to use and where to find them (the "Report navigator" in View > Navigators > Reports) in more detail.
You don't have to integrate Fastlane Snapshot for this. The only trick Snapshot is doing to force screenshot is triggering this code:
XCUIDevice.shared().orientation = .unknown
This will not alter UI as described on Snapshot documentation.
Unfortunately this will not work if you're using expectation for your predicate and you put this code into waitForExpectations(timeout:handler:) handler closure and I don't know why.
To workaround this you can create your own XCTestObservation handler like this:
class MockObserver: NSObject, XCTestObservation {
func testCase(_ testCase: XCTestCase, didFailWithDescription description: String, inFile filePath: String?, atLine lineNumber: UInt) {
XCUIDevice.shared().orientation = .unknown
}
}
XCTestObservationCenter.shared().addTestObserver(MockObserver())
You can put this code in either setUp() method or specific test... method.
The test output is a little weird as it will show "Set device orientation to Unknown" as an error and actual predicate error inside but you will have your screenshot:
You can override the recordFailure method to capture screenshots on any kinds of failures.
override func recordFailure(withDescription description: String, inFile filePath: String, atLine lineNumber: Int, expected: Bool) {
add(XCTAttachment(screenshot: XCUIScreen.main.screenshot()))
super.recordFailure(withDescription: description, inFile: filePath, atLine: lineNumber, expected: expected)
}
I'm actually on swift 2.3.
Inbound Call works great with CallKit. But OutGoing Call ....
I saw the SpeakerBox project, I do the same things.
But it doesn't work.
To start my call, I used
let handle = CXHandle(type: .PhoneNumber, value: "TOTO")
let startCallAction = CXStartCallAction(callUUID: uuid, handle: handle)
startCallAction.video = video
let transaction = CXTransaction()
transaction.addAction(startCallAction)
requestTransaction(transaction)
After, in SpeakerBox Project, this function is called :
func provider(provider: CXProvider, perform action: CXStartCallAction)
But not in my project. Then, when i hangup, i see : "Call failed".
Do you have an idea ?
Be sure you are configuring your CXProvider and setting its delegate properly. If you do not set the CXProvider's delegate property, the delegate will not receive any actions to perform.
Also, if you see a "Call Failed" UI, this may indicate your app is crashing. I'd check for crash logs or run the app in the debugger.
As far as I can see, SpeakerBox demo does not perform the following provider method:
https://developer.apple.com/documentation/callkit/cxprovider/1930701-reportcall
func reportCall(with UUID: UUID,
endedAt dateEnded: Date?,
reason endedReason: CXCallEndedReason)
- (void)reportCallWithUUID:(NSUUID *)UUID endedAtDate:(nullable NSDate
*)dateEnded reason:(CXCallEndedReason)endedReason;
Which leads to the "Call failed" UI screen being displayed - as CallKit was not given a reason why the call has ended, and it seems that "
CXCallEndedReasonFailed" is assumed by default.
Call "reportCall endedAt" before requesting the CXEndCallAction transaction to remove "Call failed" screen.
Have you added the required permissions to your info.plist?
I have found a few questions regarding this issue, yet none of them were helping with my problem. I am trying to save an object to core data using this code (which worked perfectly fine in Xcode 6 and Simulator...):
let fetchRequest = NSFetchRequest(entityName: "Patient")
let fetchedResults : [NSManagedObject]!
do {
fetchedResults = try managedContext.executeFetchRequest(fetchRequest) as! [NSManagedObject]
patienten = fetchedResults
} catch {
print("error")
}
I added the do-try-catch once I started working on this project in the Xcode 7 beta and a physical device.
Now, when I hit the Save button, this piece of code is called, the app freezes and I get the following:
warning: could not load any Objective-C class information from the dyld shared cache. This will significantly reduce the quality of type information available.
Does anybody know where I went wrong?
For anyone coming across this in the future, I just ran into this problem myself and it turned out that I was actually getting a stack overflow from a recursive function.
Apparently calling setValue:forKey: on an NSObject calls the respective set[Key] function, where [Key] is the (capitalized) name you gave to the forKey section.
So, if like me, you have code that looks like the following, it will cause an infinite loop and crash.
func setName(name: String) {
self.setValue(name, forKey: "name")
}
Choose Product > Clean
I had similar issue. I deleted the app from the device. Then "Product->Clean" in the XCode menu. When I ran the app again, the issue got resolved.
Swift 3:
Actually this problem happened often when you have any property in input declared as type NSError and the compiler expect an Error output, so change the input type to Error usually solve this issue.
What helped me in similar problem (xCode 7, Swift 2):

Or more quickly without explaining the reason of solution: just comment #objc(className) in your NSManagedObjectSubclass , that was generated from your CoreData Entity (#objc(Patient) - in your case ).
This solution (if issue still appears) does not applicable to xCode 7.1/Swift 2.1, as the way of generating NSManagedObjectSubclasses was changed.
Don't forget about cleaning your project (Product > Clean) and deleting the app from your device/simulator to replace CoreData storage on it.
let fetchRequest = NSFetchRequest(entityName: "Patient")
do {
let fetchedResults = try managedObjectContext!.executeFetchRequest(fetchRequest)
print("\(fetchedResults)")
} catch {
print("error")
}
The above code worked for me.
Maybe the issue maybe with how your core data is managed.
Check if your managedObjectContext is actually getting created.
Check the modelling of your core data
I recorded some test cases with CUIT in VS2010. Everything worked fine the day before. So, today I run again, all the test failed, with the warning: The following element is no longer available ... and I got the exception : Can't perform "Click" on the hidden control, which is not true because all the controls are not hidden. I tried on the other machine, and they failed as well.
Does anyone know why it happens? Is it because of the web application for something else? Please help, thanks.
PS: So I tried to record a new test with the same controls that said "hidden controls", and the new test worked!? I don't understand why.
EDIT
The warning "The following element blah blah ..." appears when I tried to capture an element or a control while recording. The source code of the button is said 'hidden'

Although I am running Visual Studio 2012, I find it odd that we started experiencing the same problem on the same day, I can not see any difference in the DOM for the Coded UI Tests I have for my web page, but for some reason VS is saying the control is hidden and specifies the correct ID of the element it is looking for (I verified that the ID is still the same one). I even tried to re-record the action, because I assumed that something must have changed, but I get the same error.
Since this sounds like the same problem, occurring at the same time I am thinking this might be related to some automatic update? That's my best guess at the moment, I am going to look into it, I will update my post if I figure anything out.
EDIT
I removed update KB2870699, which removes some voulnerability in IE, this fixed the problems I was having with my tests. This update was added on the 12. september, so it fits. Hope this helps you. :)

The problem is more serious than that! In my case I can't even record new Coded UI Tests. After I click in any Hyper Link of any web page of my application the coded UI test builder cannot record that click "The following element is no longer available....".
Apparently removing the updates, as said by AdrianHHH do the trick!
Shut down VS2010, launch it again "Run as administrator".
There may be a field in the SearchProperties (or possible the FilterProperties) that has a value set by the web site, or that represents some kind of window ID on your desktop. Another possibility is that the web page title changes from day to day or visit to visit. Different executions of the browser or different visits to the web page(s) create different values. Removing these values from the SearchProperties (or FilterProperties) or changing the check for the title from an equals to a contains for a constant part of the title should fix the problem. Coded UI often searches for more values than the minimum set needed.
Compare the search properties etc for the same control in the two recorded tests.
Update based extra detail given in the comments:
I solved a similar problem as follows. I copied property code similar to that shown in your question into a method that called FindMatchingControls. I checked how many controls were returned, in my case up to 3. I examined various properties of the controls found, by writing lots of text to a debug file. In my case I found that the Left and Top properties were negative for the unwanted, ie hidden, controls.
For your code rather than just using the UIAbmeldenImage property, you might call the method below. Change an expression such as
HtmlImage im = UIMap.abc.def.UIAbmeldenImage;
to be
HtmlImage im = FindHtmlHyperLink(UIMap.abc.def);
Where the method is:
public HtmlImage FindHtmlHyperLink(HtmlDocument doc)
{
HtmlImage myImage = new HtmlImage(doc);
myImage.SearchProperties[HtmlImage.PropertyNames.Id] = null;
myImage.SearchProperties[HtmlImage.PropertyNames.Name] = null;
myImage.SearchProperties[HtmlImage.PropertyNames.Alt] = "abmelden";
myImage.FilterProperties[HtmlImage.PropertyNames.AbsolutePath] = "/webakte-vnext/content/apps/Ordner/images/logOut.png";
myImage.FilterProperties[HtmlImage.PropertyNames.Src] = "http://localhost/webakte-vnext/content/apps/Ordner/images/logOut.png";
myImage.FilterProperties[HtmlImage.PropertyNames.LinkAbsolutePath] = "/webakte-vnext/e.consult.9999/webakte/logout/index";
myImage.FilterProperties[HtmlImage.PropertyNames.Href] = "http://localhost/webakte-vnext/e.consult.9999/webakte/logout/index";
myImage.FilterProperties[HtmlImage.PropertyNames.Class] = null;
myImage.FilterProperties[HtmlImage.PropertyNames.ControlDefinition] = "alt=\"abmelden\" src=\"http://localhost/web";
myImage.FilterProperties[HtmlImage.PropertyNames.TagInstance] = "1";
myImage.WindowTitles.Add("Akte - Test Akte Coded UI VS2010");
UITestControlCollection controls = myImage.FindMatchingControls();
if (controls.Count > 1)
{
foreach (UITestControl con in controls)
{
if ( con.Left < 0 || con.Top < 0 )
{
// Not on display, ignore it.
}
else
{
// Select this one and break out of the loop.
myImage = con as HtmlImage;
break;
}
}
}
return myImage;
}
Note that the above code has not been compiled or tested, it should be taken as ideas not as the final code.
I had the same problem on VS 2012. As a workaround, you can remove that step, and re-record it again. That usually works.
One of the biggest problem while analyzing the Coded UI test failures is that the error stack trace indicates the line of code which might be completely unrelated to the actual cause of failure.
I would suggest you to enable HTML logging in your tests - this will display step by step details of how Coded UI tried to execute the tests - with screenshots of your application. It will also highlight the control in red which Coded UI is trying to search/operate upon.This is very beneficial in troubleshooting the actual cause of test failures.
To enable tracing you can just add the below code to your app.config file --
If I write a helper method for test case:
- (void)testCallsHelper
{
[self helper]; // Can I get Xcode to highlight the failure here?
}
- (void)helper
{
STFail(#"Fail"); // Xcode highlights failure here
}
This would be handy because it's quicker to use Xcode highlighting to jump to where an error is occurring and its also handy to put repeated code into helper method.
