"Reveal in Project Navigator" Shortcut Stopped Working
Today after I apparently fat fingered/misclicked/misdragged something in Xcode, the short cut for "Reveal in Project Navigator" (cmd+shift+J) stopped working for me. I don't have any custom shortcut bindings and the other shortcuts still work, as far as I can tell. I've deleted and re-installed Xcode; I've run defaults delete com.apple.dt.Xcode to no avail. I'd really like this shortcut back as it's probably my second or third most used one :(

testSession.setSimulatedError(.purchase(.invalidQuantity), forAPI: .purchase)
I am trying to test this simulated Error. The issue is, I can't get this to trigger through the simulatedError function. Error will always end up as an unknown error Example code snippet: @available(iOS 17.0, *) func testPurchase_InvalidQuantity() async throws { // Arrange testSession.clearTransactions() testSession.resetToDefaultState() let productID = "consumable_1" try await testSession.setSimulatedError(.purchase(.invalidQuantity), forAPI: .purchase) guard let product = await fetchProduct(identifier: productID) else { XCTFail("Failed to fetch test product") return } let option = Product.PurchaseOption.quantity(4) let result = await manager.purchase(product: product, options: option) switch result { case .success: XCTFail("Expected failure due to invalid quantity") case .failure(let error): print("Received error: \(error.localizedDescription)") switch error { case .purchaseError(let purchaseError): XCTAssertEqual(purchaseError.code, StoreKitPurchaseError.invalidQuantity.code) default: XCTFail("Unexpected error: \(error)") } } } In the above code snippet, I have an Unexpected Error. But if i remove try await testSession.setSimulatedError(.purchase(.invalidQuantity), forAPI: .purchase) I will receive a XCTFail in the success of my result. So when I set the quantity to a -1, only then can I correctly receive an invalidQuantity. Does anyone know why the try await testSession.setSimulatedError(.purchase(.invalidQuantity), forAPI: .purchase) would fail to work as directed? I have tests for all the generic errors for loadProducts API and the simulatedError works great for them

ccache in xcode 16
I have a xcode project generated by unity 6 my mac: my x-code: It's a simple project but the building time lasted over 10 minutes and I found a page https://discussions.unity.com/t/optimizing-ios-and-macos-build-times-using-ccache/809570 I tried to run ccache in my mac and hope to accelerate the building. I installed ccache in my MAC by brew I made two script with +x mode I created a testc folder to verify the script and it did work. Then I opened the xcode and added CC and CXX to the “Build Settings” I triggered the building But it didn’t work, the building used the default compiler. I had repeated to ask AI about it and cleaned building cache many times, but the problem still exists. Even without any probing executing of the ccache-clang script ( I configured the log file position, so if it has been executed once, there will be some logs) Could someone help me check if there’s something wrong?

XCode 16.2 is randomly removing my account
I am signed into Xcode for automatic signing. Which works for a random amount of builds and then the Account/AppleID dissappears from Xcode. This is a vital part of our CI/CD processes and disrupts the workflow alot. MacOS version: Apple M2 15.3 (24D60) Sequoia related: https://developer.apple.com/forums/thread/724434 https://stackoverflow.com/questions/50252887/account-automatically-removed-from-xcode

Change app language on Apple Watch simulator
I feel a bit dumb now. I once succeeded to change the language of an app on Watch simulator. So it is possible. And I'm not able to repeat (fool of me I did not took note of how I did it). I just remember it was simply through some language settings selection, may be rebooting the Mac, but not by changing anything in code. Does someone know how to do ?

Gaps in Xcode build timeline
Reposting (after a while) from the Swift forums - the build timeline for our project has a lot of weird gaps in the beginning - almost 15 seconds in total, which is quite a big chunk of the total build time. Is there any way to determine why they exist or how I could fix them? I hope it's just something hidden and not the build system literally doing nothing... This is on Xcode 15.4.

Xcode 16 Crash While Validating (com.apple.root.default-qos)
Hello, We're attempting to validate our application archive through Xcode but the application is crashing during the validate step and we're not sure why. Platform: macOS 15.1 Arch: arm64 We've confirmed that our developer agreements are up to date (a suggestion made by other posts on these forums). Other suggestions have been to downgrade Xcode but we're hoping there's another explanation. The application is quite complex - many libraries and framework - but executes as expected during development and testing. Crash Report Any insight into this error would be appreciated. We're sure it's something wrong with our plist or archive structure but the crash is limiting our ability to debug.

How to identify apps in FamilyActivitySelection?
Questions I am developing a social screen time application that enables users to create “sprints” and set sprint goals—essentially time limits on usage for selected applications. For this functionality, users select the apps they wish to manage using the FamilyActivitySelection interface (from the FamilyControls framework). However, our backend needs to distinguish each application uniquely (for example, via the app’s bundle identifier) in order to correctly map and enforce user-defined sprint goals. Unfortunately, we are encountering an issue where retrieving the bundle identifier directly from the FamilyActivitySelection is returning nil. As a result, we are unable to globally identify the selected apps. Could you please advise if there is an alternative method or property available in the FamilyControls API that would allow us to uniquely identify the apps? Alternatively, is there another approach recommended by Apple for obtaining a global identifier for applications selected via FamilyActivitySelection? Thank you for your time and assistance. I look forward to your guidance on how to resolve this issue. Code The following is the print statement I used to check if bundleIdentifier is nil after I stored user's selections to the variable selection using familyActivityPicker: for app in selection!.applications { let bundleId = app.bundleIdentifier ?? "Unknown Bundle ID" let token = app.token let localizedDisplayName = app.localizedDisplayName ?? "Unknown Localized Display Name" print("Selected app bundle identifier: \(bundleId)") print("localizedDisplayName: \(localizedDisplayName)") } Console log result I received from the print statement above: Selected app bundle identifier: Unknown Bundle ID localizedDisplayName: Unknown Localized Display Name

XCFrameworks deploying .a / include to output target directory
Hello Friends, We have a strange bug that Xcode is deploying static binaries from within .XCFramework into the CONFIGURATION_BUILD_DIR An example of our xcframeworks structure is: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>AvailableLibraries</key> <array> <dict> <key>BinaryPath</key> <string>libglfw3.a</string> <key>HeadersPath</key> <string>Headers</string> <key>LibraryIdentifier</key> <string>macos-arm64_x86_64</string> <key>LibraryPath</key> <string>libglfw3.a</string> <key>SupportedArchitectures</key> <array> <string>arm64</string> <string>x86_64</string> </array> <key>SupportedPlatform</key> <string>macos</string> </dict> </array> <key>CFBundlePackageType</key> <string>XFWK</string> <key>XCFrameworkFormatVersion</key> <string>1.0</string> </dict> </plist> for open source creative coding toolkit https://github.com/openframeworks/openFrameworks Can you see any issues in the above. Some ideas for me is to generate xcarchive instead of deploying the .a in the xcframeworks, however that does not explain the include being packaged there, so I think this might be a Xcode issue

Xcode 16 is running on an iPhone 7 with iOS 12.1.3. The application fails to open normally and crashes immediately upon startup.
I am currently using Xcode 16 (16A242d) and testing on an iPhone 7 running iOS 12.1.3. However, when I try to launch the app on the device, it crashes immediately.

Even after archiving and installing the app, it still crashes. According to the official documentation, Xcode 16 is supposed to support iOS 12, but this issue persists. I would like to know the possible reasons for this behavior.

Run on multiple simulators
I am developing a game that has 3 team members. I can manually start up 3 simulators and run the game for developing/testing but seem like there should be a simple way to click build/run and have it launch on all three automatically. Does anyone know how to do this or if its even possible without writing some scripts?

Build input file cannot be found
Hi! When I run my project on a real device (iPhone 15 Pro), I encounter the following error: Build input file cannot be found: '/Users/Interexy/Library/Developer/Xcode/DerivedData/SinglePhotoBook-geecnphrjebsisdmhcyzlsefvphm/Build/Products/Debug-iphoneos/SinglePhotoBook.app/SinglePhotoBook'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it? How can I solve this? I've already reinstalled Pods and cleaned DerivedData a million times, but the issue persists. Xcode: Version 15.4

How to Mark Unused Code (Methods, Properties, Classes) in Xcode for Deletion
Is there a way to mark unused parts of the code? I am developing an app using Objective-C, and I want to delete methods, properties, and classes that are not used in the code. In IDEA, this feature works well, with unused methods grayed out. However, Xcode doesn't have this functionality, making it inconvenient for me to remove unused code.

Adding custom document icon for document based Mac OS 16 App
Starting with Mac OS 16, Document Icons can be generated by defining a background and a Foreground element (see Apple Documentation). I've defined the mentioned elements in my Assets and in the info.plist. Unfortunately I still can't see my custom icons. Neither on existing files, nor on newly saved files. I even added a Legacy Icon - which is also not shown in Mac OS. The full source code of the app is over at gitHub . Would be great if someone could point out what I'm not seeing here. Thanks a lot, Holger Here the relevant part of the info.plist <array> <dict> <key>CFBundleTypeIconFile</key> <string>Legacy</string> <key>CFBundleTypeIconSystemGenerated</key> <integer>1</integer> <key>CFBundleTypeName</key> <string>StateTransfer Request</string> <key>CFBundleTypeRole</key> <string>Editor</string> <key>LSHandlerRank</key> <string>Default</string> <key>LSItemContentTypes</key> <array> <string>de.holgerkrupp.statetransfer.request</string> </array> <key>NSDocumentClass</key> <string>NSDocument</string> </dict> </array> <key>UTExportedTypeDeclarations</key> <array> <dict> <key>UTTypeConformsTo</key> <array/> <key>UTTypeDescription</key> <string>StateTransfer Request</string> <key>UTTypeIconFile</key> <string>Legacy</string> <key>UTTypeIcons</key> <dict> <key>UTTypeIconBackgroundName</key> <string>IconBackground</string> <key>UTTypeIconBadgeName</key> <string>IconForeground</string> <key>UTTypeIconText</key> <string>REST</string> </dict> <key>UTTypeIdentifier</key> <string>de.holgerkrupp.statetransfer.request</string> <key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>httprequest</string> </array> <key>public.mime-type</key> <array> <string>application/json</string> </array> </dict> </dict> </array> <key>UTImportedTypeDeclarations</key> <array> <dict> <key>UTTypeConformsTo</key> <array/> <key>UTTypeDescription</key> <string>StateTransfer Request</string> <key>UTTypeIconFile</key> <string>Legacy</string> <key>UTTypeIcons</key> <dict> <key>UTTypeIconBackgroundName</key> <string>IconBackground</string> <key>UTTypeIconBadgeName</key> <string>IconForeground</string> <key>UTTypeIconText</key> <string>REST</string> </dict> <key>UTTypeIdentifier</key> <string>de.holgerkrupp.statetransfer.request</string> <key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>httprequest</string> </array> <key>public.mime-type</key> <array> <string>application/json</string> </array> </dict> </dict> </array>
