Xcode Cloud - slow test-without-building step
Hi, I'm currently researching if we are able to migrate to Xcode Cloud in our project. I encountered one issue. I run unit tests on Xcode Cloud and I see that they finish in ~150 seconds, but the whole step takes ~530s and there is no information in logs why. I even run the same command on my local computer and it doesn't take that long. Any ideas? Any way to optimize it? Also one more thing: it looks like Xcode Cloud is not running on M1 machines. Do you know guys if there are plans for Xcode Cloud to take advantage of M1/M2?

XCTestCase performance measurement has no results on M1
I want to test app launch performance in my project. Therefore I tried to use performance test with measure func and XCTApplicationLaunchMetric. But after test completion there is no any result with average time. Here is a test example: func testLaunchPerformance() throws {         if #available(macOS 10.15, iOS 13.0, tvOS 13.0, watchOS 7.0, *) {             // This measures how long it takes to launch your application.             measure(metrics: [XCTApplicationLaunchMetric()]) {                 XCUIApplication().launch()             }         }     } But when I create a new empty project and add the same performance test – it works and shows app launch results. 1st image is a real project test – there is no test result. and the 2nd image is a demo empty project test – it has performance result diagram. I am running test on MacBook with M1 Pro chip. However, when my colleague is running the same performance test on our real project with Intel based MacBook Pro – all is fine, it shows app launch results correctly as my demo project. I have no idea how it can be fixed, because it seems that it depends on M1 chip 🤷🏻‍♂️. May be somebody have a solution?

iOS 15 - UI Test keeps asking pin code for "Enable UI Automation"
We got the newly issue that our Test devices keeps us asking for the pin code to "Enable UI Automation". Then it works for some hours or days, but after some time it starts again. "Enable UI Automation" is already enabled in "Settings" - "Developer" menu. The devices are located remotely and we can't access them directly, so this is a big issue for us right now. Is there any way to avoid this?

Unable to tap SwiftUI menu with XCUITest (ios15)
I have a SwiftUI menu Menu{ .... }, label : { Image(...).accessibility(identifier: "cardMenu") } I used to be able to bring up the menu (before upgrading to xcode 13 (ios15)) like this let app = XCUIApplication() app.launch() app.buttons["cardMenu"].tap() But now i am unable to see the identifier in app.buttons. Can't seem to find the identifier anymore. I've tried looking for the identifier in the other app fields and changing to use text instead of identifer. No luck. These tests used to work prior to the upgrade. Any help would be appreciated

Enable local network access during iOS UI test in iOS14
We are building an iOS app that connects to a device using Bluetooth. To test unhappy flow scenarios for this app, we'd like to power cycle the device we are connecting to by using an IoT power switch that connects to the local network using WiFi (a Shelly Plug-S). In my test code on iOS13, I was able to do a local HTTP call to the IP address of the power switch and trigger a power cycle using its REST interface. In iOS 14 this is no longer possible, probably due to new restrictions regarding local network usage without permissions (see: https://developer.apple.com/videos/play/wwdc2020/10110 ). When running the test and trying a local network call to the power switch in iOS14, I get the following error: Task <D206B326-1820-43CA-A54C-5B470B4F1A79>.<2> finished with error [-1009] Error Domain=NSURLErrorDomain Code=-1009 "The internet connection appears to be offline." UserInfo={_kCFStreamErrorCodeKey=50, NSUnderlyingError=0x2833f34b0 {Error Domain=kCFErrorDomainCFNetwork Code=-1009 "(null)" UserInfo={_kCFStreamErrorCodeKey=50, _kCFStreamErrorDomainKey=1}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <D206B326-1820-43CA-A54C-5B470B4F1A79>.<2>, _NSURLErrorRelatedURLSessionTaskErrorKey=("LocalDataTask <D206B326-1820-43CA-A54C-5B470B4F1A79>.<2>"), NSLocalizedDescription=The internet connection appears to be offline., NSErrorFailingURLStringKey=http://192.168.22.57/relay/0?turn=on, NSErrorFailingURLKey=http://192.168.22.57/relay/0?turn=on, _kCFStreamErrorDomainKey=1} An external network call (to google.com) works just fine in the test. I have tried fixing this by adding the following entries to the Info.plist of my UI test target: <key>NSLocalNetworkUsageDescription</key> <string>Local network access is needed for tests</string> <key>NSBonjourServices</key> <array> <string>_http._tcp</string> </array> <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> However, this has no effect. I have also tried adding these entries to the Info.plist of my app target to see if that makes a difference, but it doesn't. I'd also rather not add these entries to my app's Info.plist, because the app does not need local network access. Only the test does. Does anyone know how to enable local network access during an iOS UI test in iOS14?
