So yesterday I noticed that some of images in my app stopped appearing. All of them were placed in the on-demand resources, that is I've assigned tags to them. Up until yesterday they were working correctly but since then whenever I try to load the assets I get the error message saying: Error Domain=NSCocoaErrorDomain Code=4099 "Connection invalidated to streaming unzip service." My code for loading the asset is pretty straightforward and it was working perfectly fine before: let resourceRequest = NSBundleResourceRequest(tags: ["vinyl"]) defer { resourceRequest.endAccessingResources() } do { if await !resourceRequest.conditionallyBeginAccessingResources() { try await resourceRequest.beginAccessingResources() } } catch { assertionFailure("Vinyl image was not available, error: \(error)") } I'm obviously using it in asynchronous context, but the old method which used completion handler gives me the same error. Has anyone encountered this issue as well? I just updated my devices to iOS 15.5, maybe that update broke on-demand resources? Tested on Xcode 13.4, iOS 15.5

Hi community: I'm coming across two error types on Xcode cloud during ui tests. encountered an error (Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying Error: Test crashed with signal kill before starting test execution. If you believe this error represents a bug, please attach the result bundle at /Volumes/workspace/resultbundlexcresult)) encountered an error (Failed to prepare device 'Clone 7 of iPhone 14 Pro' for impending launch. If you believe this error represents a bug, please attach the result bundle at /Volumes/workspace/ resultbundle.xcresult. (Underlying Error: Unable to boot the Simulator. launch failed to respond. (Underlying Error: Failed to start launch_ sim: could not bind to session, launchd_sim may have crashed or quit responding))) Any ideas on how to solve them? Thanks

What happened to CMD-Option-Click in Xcode 26 for opening a symbol in a new editor split pane? This was one of the most usefull shortcuts. Xcode 26 is a pain to use without it.

Hi everyone, After updating my Mac and Xcode to 26, I’m running into a consistent crash whenever I try to launch an app from Xcode. Environment: Mac: Apple Silicon M3 macOS: 26.0 (25A354) Xcode: 26.0.1 (17A400) Issue: When I press Run on any project (including new, empty projects), Xcode immediately crashes. This started only after updating to the latest macOS and Xcode. Crash details: The crash log shows: Application Specific Signatures: ___localError Thread 0 crashed inside -[IDEScheme _executionOperationForSchemeOperationParameters:...] from IDEFoundation/IDEKit. I also noticed background threads calling DVTPortal (developer portal requests) right before the crash. What I’ve tried so far: Cleared DerivedData, ModuleCache.noindex, and Xcode caches. Signed out/in of my Apple ID in Xcode. Recreated project schemes. Verified provisioning profiles. Reinstalled Xcode 26. Unfortunately, the crash still happens. Question: Is this a known issue with Xcode 26 on Apple Silicon (M3)? Has anyone seen a workaround? Any guidance would be greatly appreciated — I can’t currently launch apps in Xcode at all. Thanks!

Ever since updating to Xcode 16.3, auto-completing variable names in lldb does not work. Is this a known bug? Is there a workaround to get it do auto-complete again?

My Xcode version is 16.4, I have added an old version simulator (iPhone 13 with iOS 17.2) to the simulator list, but I can't use it for debugging, and all on display are iPhone 16 with 18.6 (the latest iOS devices). The setting "Minimum Deployments" for my App is 16.6. In addition, when I downloaded an iOS 16.0 version simulator, Xcode automatically added all iPhone 15 models of the simulator, but I still can't use them. In short, I can only use the default iPhone 16 simulators. So, if I want to debug my App using iPhone 13 (iOS 17.2), what should I do? Thank you for your reply. :) Another small issue, my App's destination has been set to support only iPhone, why are those iPad simulators still appearing?

I'm trying to create a preview for my live activities when it's stale, so I created a preview provider. I followed some examples, but XCode says I'm missing preview context. Am I doing something wrong? I tried adding .previewContext(WidgetPreviewContext(family: .systemSmall)) but that doesn't seem to work.

I'm unable to debug on iPhone 12 running iOS 17 beta 3 via network. I'm running Xcode 15 beta 6 Device shows in devices and simulators and I can debug when connected with cable. However the "Connect Via Network" option is frayed out, oddly however the checkbox is ticked I'm developing a app using RoomPlan so network connectivity is a must for debugging Anyone else encountered this and know how to get around this problem Other devices running iOS 16 connect via network just fine

We use several UIKit and AVFoundation APIs in our project, including: setAlternateIconName(_:completionHandler:) getAllTasks(completionHandler:) loadMediaSelectionGroup(for:completionHandler:) Moreover, we use the Swift Concurrency versions for these APIs: @MainActor func setAlternateIconName(_ alternateIconName: String?) async throws var allTasks: [URLSessionTask] { get async } func loadMediaSelectionGroup(for mediaCharacteristic: AVMediaCharacteristic) async throws -> AVMediaSelectionGroup? Everything worked well with these APIs in Xcode 16.2 and earlier, but starting from Xcode 16.3 (and in 16.4), they cause crashes. We've rewritten the APIs to use completion blocks instead of async/await, and this approach works. Stack traces: setAlternateIconName(_:completionHandler:) var allTasks: [URLSessionTask] { get async } loadMediaSelectionGroup(for:completionHandler:) Also, I attached some screenshots from Xcode 16.4.

Hello, I am using Xcode 16.1 (16B40) on MacOS Sequoia 15.1.0 using a Macbook pro M1 Max I am developing an app for iOS 17 and 18 using SwiftUI I created UITests to take the screenshots for the appStore on the simulator The tests run well and all of them are succeded The problem appears when I try to get the screenshot files from the xcresult files after the test. There is not any screenshot inside it. I found a data folder and a Info.plist file. In the data folder there are a lot of files with this pattern data.03zD4C6IGFFthK14NwA8mNvcwFHT16g6Tl40Tl1YmBC1bNh6d0YIcnWKyUaQPDXoa8fYo6C3Xcv8xvMtE3_NEXA== and other files with this pattern refs.03zD4C6IGFFthK14NwA8mNvcwFHT16g6Tl40Tl1YmBC1bNh6d0YIcnWKyUaQPDXoa8fYo6C3Xcv8xvMtE3_NEXA== Ok, I tryed to use fastlane to automatize the screenshots but the problem is still present. The xcresult files have not any png file. I had no problems doing this action (getting screenshots from a xcresult file) in previous versions of MacOS and Xcode in my current machine. I just updated my machine to MacOS Sequoia 15.1.1 and the problem is still present Honestly I don't know how to fix this situation. With Xcode 15 I had not any problem with that but I am not sure if Xcode 16.0 was runing without problems because I didn't need to use this functionality in those months Here is my code for a UITest: import XCTest final class ScreenshotsUITests: XCTestCase { let app = XCUIApplication() let device = "iPhone16" override func setUpWithError() throws { continueAfterFailure = true } override func tearDownWithError() throws {} @MainActor func testEnglishScreens() throws { let lang = "en" app.launchArguments.append("UITestMode") app.launchArguments += ["-AppleLanguages", "(en)"] app.launchArguments += ["-AppleLocale", "en_US"] app.launch() executeTestsForMenus(lang: lang, backLabel: "Back") executeTestForMatch(lang: lang) } @MainActor func testSpanishScreens() throws { let lang = "es" app.launchArguments.append("UITestMode") app.launchArguments += ["-AppleLanguages", "(es)"] app.launchArguments += ["-AppleLocale", "es_ES"] app.launch() executeTestsForMenus(lang: lang, backLabel: "Atrás") executeTestForMatch(lang: lang) } private func executeTestForMatch(lang: String) { let startButton = app.buttons["start-button"] startButton.tap() let key4 = app.buttons["key-4"] XCTAssertTrue(key4.waitForExistence(timeout: 30), "Key 4 in match screen is not found") key4.tap() let key2 = app.buttons["key-2"] XCTAssertTrue(key2.exists, "Key 2 in match screen is not found") key2.tap() makeScreenShot("playing", lang: lang) let closeButton = app.buttons["close-button"] XCTAssertTrue(closeButton.exists, "Close button in match screen is not found") closeButton.tap() } private func executeTestsForMenus(lang: String, backLabel: String) { let mainHeader = app.staticTexts["Math match"] XCTAssertTrue(mainHeader.exists, "Header in main screen is not found") makeScreenShot("mainMenu", lang: lang) let settingsButton = app.buttons["settings-button"] XCTAssertTrue(settingsButton.exists, "Settings button in main screen is not found") settingsButton.tap() makeScreenShot("Settings", lang: lang) let backButton = app.buttons[backLabel] XCTAssertTrue(backButton.exists, "Back button in match screen is not found") backButton.tap() let helpButton = app.buttons["help-button"] XCTAssertTrue(helpButton.exists, "Help button in main screen is not found") helpButton.tap() makeScreenShot("Help", lang: lang) backButton.tap() let scoreButton = app.buttons["score-button"] XCTAssertTrue(scoreButton.exists, "Scores button in main screen is not found") scoreButton.tap() makeScreenShot("Scores", lang: lang) backButton.tap() let playButton = app.buttons["play-button"] XCTAssertTrue(playButton.exists, "Play button in main screen is not found") playButton.tap() makeScreenShot("matchBuilder", lang: lang) let startButton = app.buttons["start-button"] XCTAssertTrue(startButton.exists, "Start button in match builder screen is not found") } private func makeScreenShot(_ name: String, lang: String) { takeScreenshot(app, named: "\(lang)-\(name)-\(device)") } } import XCTest extension XCTestCase { func takeScreenshot(_ app: XCUIApplication, named name: String, fullScreen: Bool = false) { let screenshot: XCUIScreenshot if fullScreen { screenshot = app.windows.firstMatch.screenshot() } else { screenshot = XCUIScreen.main.screenshot() } let screenshotAttachment = XCTAttachment( uniformTypeIdentifier: "public.png", name: "screenshot-\(name).png", payload: screenshot.pngRepresentation, userInfo: nil) screenshotAttachment.lifetime = .keepAlways add(screenshotAttachment) } } and here is the content of my testplan file: { "configurations" : [ { "id" : "35BC7C0B-9A5A-4027-9F30-36958C4C1AAF", "name" : "Test Scheme Action", "options" : { "preferredScreenCaptureFormat" : "screenshot", "testExecutionOrdering" : "random", "uiTestingScreenshotsLifetime" : "keepAlways", "userAttachmentLifetime" : "keepAlways" } } ], "defaultOptions" : { "targetForVariableExpansion" : { "containerPath" : "container:myAppProject.xcodeproj", "identifier" : "B27D1B022CA00314001A259B", "name" : "MyAppProject" } }, "testTargets" : [ { "parallelizable" : true, "target" : { "containerPath" : "container:MyAppProject.xcodeproj", "identifier" : "B27D1B122CA00315001A259B", "name" : "MyAppProjectTests" } }, { "parallelizable" : true, "target" : { "containerPath" : "container:MyAppProject.xcodeproj", "identifier" : "B27D1B1C2CA00315001A259B", "name" : "MyAppProjectUITests" } } ], "version" : 1 } I made tests with old projects in my machine and those projects have the same problem with screenshot files in the xcresult bundles I don't know if the problem is in my machine, my Xcode, MacOS or other ting. I don't know how to fix this problem Please, can anyone help me? Thanks in advance

I just downloaded Xcode26, and am trying to download the new simulator to be able to run and test my app. But the downloads folder just shows that it's stuck on "Fetching download information ..." even 15 minutes after it started. I tried restarting Xcode but didn't help. Internet connection is good. Any tips to get it working?

After changing Xcode 16.2 with min iOS 15. I got error in debug mode Assertion failed: (reconstituted == accumulator), function setFixup64, file OutputFile.cpp, line 2975. But project still can archive to IPA. Anyone has the same issue as me?

I am missing device support for IOS 18.5 in xcode. I tried installing xcode 16.4, xcode 16.4 beta and xcode 26 beta 2 but none of them generated folder for 18.5. Is this happening only for me or everyone. Please provide me 18.5 folder if anyone has it. I would appreciate a lot.
