Hello all ! I am starting to explore UI testing with XCode and was wondering if there's a simple way to access application logs directly in XCode after the session ends. We currently have access to many things (captures, video, xctest logs) in report UI (see capture) but I am surprised we don't also have the app logs. I know there's a way of accessing it via terminal in .xcresult via a custom script (https://github.com/ChrisMash/XCResultExtractor) but I find it a little tedious and unfriendly as it gives raw .txt I also noticed I can switch processes in XCode console to see app logs but it switches back to xctest logs once the test ends ^^' Is there some "see app logs" button I missed in XCode UI or is XCResultExtractor our only option ? Thank you in advance !

Hello all! My application written with C++ for iOS. Want to make some functionality in static library for the purpose of reuse it in different C++ projects. Want to make universal library for using StoreKit2. Global idea is to wrap StoreKit2 Swift out with CPP interoperability. Now trying to make clear for my self how to create C++ static library with Swift interoperability for iOS in XCode. There are only Objective-C option when you creating static library in XCode for iOS. Is it correct: Create Static Library with Objective-C in XCode Remove all default Objective-C files Add C++ files Add C++/Swift interoperability in build settings Add swift classes Beside all of it some questions: When C++ static library contain Swift code with interoperability will it require some special settings for project (Swift standard lib or some other settings)? Or it could be used like any other C++ libraries? What is the optimal build settings in this case to reduce dependencies when using it different projects? Is there any examples of the same approach for iOS development?

Hey everyone, I’m learning async/await and trying to fetch an image from a URL off the main thread to avoid overloading it, while updating the UI afterward. Before starting the fetch, I want to show a loading indicator (UI-related work). I’ve implemented this in two different ways using Task and Task.detached, and I have some doubts: Is using Task { @MainActor the better approach? I added @MainActor because, after await, the resumed execution might not return to the Task's original actor. Is this the right way to ensure UI updates are done safely? Does calling fetchImage() on @MainActor force it to run entirely on the main thread? I used an async data fetch function (not explicitly marked with any actor). If I were to use a completion handler instead, would the function run on the main thread? Is using Task.detached overkill here? I tried Task.detached to ensure the fetch runs on a non-main actor. However, it seems to involve unnecessary actor hopping since I still need to hop back to the main actor for UI updates. Is there any scenario where Task.detached would be a better fit? class ViewController : UIViewController{ override func viewDidLoad() { super.viewDidLoad() //MARK: First approch Task{@MainActor in showLoading() let image = try? await fetchImage() //Will the image fetch happen on main thread? updateImageView(image:image) hideLoading() } //MARK: 2nd approch Task{@MainActor in showLoading() let detachedTask = Task.detached{ try await self.fetchImage() } updateImageView(image:try? await detachedTask.value) hideLoading() } } func fetchImage() async throws -> UIImage { let url = URL(string: "https://via.placeholder.com/600x400.png?text=Example+Image")! //Async data function call let (data, response) = try await URLSession.shared.data(from: url) guard let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 else { throw URLError(.badServerResponse) } guard let image = UIImage(data: data) else { throw URLError(.cannotDecodeContentData) } return image } func showLoading(){ //Show Loader handling } func hideLoading(){ //Hides the loader } func updateImageView(image:UIImage?){ //Image view updated } }

I’m working on an Xcode App Playground project (.swiftpm) and trying to add a .mlmodel file (e.g., Exercises.mlmodel) to it. However, when I add the .mlmodel file to my project, I encounter the following error: Exercises.mlmodel: No predominant language detected. Set COREML_CODEGEN_LANGUAGE to preferred language. The .mlmodel file works perfectly fine when used in a regular Xcode project (.xcodeproj), but this issue occurs as soon as I add the file in an App Playground project (.swiftpm). Steps I’ve Tried: Ensuring the .mlmodel file is correctly added to the project folder. Checking the generated Core ML Swift code in a .xcodeproj environment—works as expected. Searching for a way to explicitly set COREML_CODEGEN_LANGUAGE in a .swiftpm project, but it seems that Xcode does not provide this option. Any advice or solutions would be greatly appreciated! I have tried the solutions in these articles, however none of them worked: https://medium.com/@sofiadinizms/how-to-use-coreml-in-swift-playgrounds-8d5f001c5d15 https://developer.apple.com/forums/thread/743942?answerId=776359022#776359022

None of my existing apps (both in-AppStore and in-development) nor even a brand new WatchOS app can be installed to my Apple Watch. While using Xcode to build and deploy to my Watch, I get this: ”Waiting to reconnect to Apple Watch Xcode will continue when the operation completes.” However, this dialog persists and never completes. I’m running all of the latest: MacOS 14 beta 4, Xcode 15 beta 5, Watch OS 10 beta 4, iOS 17 beta 4. I’ve tried resetting my Watch (with “Erase All” option) and restarting the Mac, the phone and the watch. Any help?

Hi, I am using xcode build that receive it's configuration using xcconfig files, those add some new definitions to the project, like the location of openssl library. If xcode environment variable include prefix that matches one of the fields in the project settings, it is automatically referred to as if you added it to that field. for example : the var HEADER_SEARCH_PATHS_openssl_libopenssl has value (openssl headers' path) that should be automatically added to the field Headers Search Paths under project settings. For some reason it stopped working for me and i'm not sure why (i've tried to release the xcconfig files). any idea why ? Thanks !

Hello dear community, I have the sample code from Apple “CapturingDepthUsingLiDAR” to access the LiDAR on my iPhone 12 Pro. My goal is to use the “photo output” function to generate a point cloud from a single image and then save it as a ply file. So far I have tested different approaches to create a .ply file from the depthmap, the intrinsic camera data and the rgba values. Unfortunately, I have had no success so far and the result has always been an incorrect point cloud. My question now is whether there are already approaches to this and whether anyone has any experience with it. Thank you very much in advance!!!

Hi I am building a framework. In the past, if I create a framework project [myFrameworkName.framework] file was created in the 'Products' folder. But my xcode doesn't create 'Products' folder. It also doesn't create [myFrameworkName.framework]. Can I make [myFrameworkName.framework] file? I do not speak English well So I am using a translator. thanks.

Hello developers, I've been building out my platform, mostly working on the Android side of a flutter app. Today I decided to make sure the iOS version wasn't getting too far behind, but when I attempted to build the app I began running into an issue I've never seen before, and after spending about 8 hours trying to figure this out, I feel like I'm more lost than when I began. The error when trying to build: Uncategorized (Xcode): Could not resolve package dependencies: downloaded archive of binary target 'grpc' from 'https://dl.google.com/firebase/ios/bin/grpc/1.65.1/rc1/grpc.zip' does not contain a binary artifact. fatalError This is a flutter app which uses firebase as a backend. I've been building with flutter/ios for about 6 years now and have never encountered this, and after searching google it appears that no one else aside from 2 people have either. I found that there's a github repo which contains this dependency as well, so I was going to try to modify the URL from the google.com url to the github url, but I'm not surewhere I would look to change this reference.. or if this is even possible. Does anyone have any experience with this error?

Getting this error several times when presenting a modal window over my splitview window when running it on my Mac using Swift/Mac Catalyst in XCode 14.2. When I click the Cancel button in the window then I get Scene destruction request failed with error: (null) right after an unwind segue. 2023-07-04 16:50:45.488538-0500 Recipes[27836:1295134] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set. 2023-07-04 16:50:45.488972-0500 Recipes[27836:1295134] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set. 2023-07-04 16:50:45.496702-0500 Recipes[27836:1295134] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set. 2023-07-04 16:50:45.496800-0500 Recipes[27836:1295134] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set. 2023-07-04 16:50:45.994147-0500 Recipes[27836:1295134] Unbalanced calls to begin/end appearance transitions for <UINavigationController: 0x7f7fdf068a00>. bleep 2023-07-04 16:51:00.655233-0500 Recipes[27836:1297298] Scene destruction request failed with error: (null) I don't quite understand what all all this means. (The "bleep" was a debugging print code I put in the unwind segue). I'm working through Apple's Mac Catalyst tutorial but it seems to be riddled with bugs and coding issues, even in the final part of the completed app which I dowmloaded and ran. I don't see these problems on IPad simulator. I don't know if it's because Catalyst has problems itself or there's something else going on that I can fix myself. Any insight into these errors would be very much appreciated! PS: The app seems to run ok on Mac without crashing despite the muliple issues

Currently, the id of my actual visionpro device is different from the xcode that works on my macmini. I added a visionpro id to xcode, but I can't build it with my visionpro. Can I log out of the existing login to xcode and log in with the same ID as visionpro? However, the appleID created for visionpro does not have an Apple Developer membership, so there is no certificate that makes it run on the actual device. How can I add my visionpro ID from the ID with my apple developer membership to run the xcode project app on visionpro? This is the first time this is the first time.

I'm trying to add an iMessage extension to my app, and upon adding the iMessage App Icon set, I ran into an issue with one specific icon size: 1024x768px, aka 1x 1024x768pt. When I remove this one icon from the icon set, it compiles and runs fine, however I can't push it to the App Store as I get the error: "Asset validation failed. Missing Image Asset. Your app is missing the Large App Icon asset 'AppIcon' in 'Payload/Runner.app/PlugIns/MessagesExtension.appex'." I'm assuming this refers to 1024x768px, as this size placeholder appears upon adding a New Messages Extension Icon to my assets folder, and 1024x1024 is already included and compiles fine with it. However, when I add the 1024x768 icon, and try to run the app, I get the error: "Command CompileAssetCatalog failed with a nonzero exit code" The app icon's filename is correct, it is exactly 1024x768 px, and my contents.json correctly includes : { "filename" : "AppIcon_1024x768.png", "idiom" : "ios-marketing", "platform" : "ios", "scale" : "1x", "size" : "1024x768" } as is the same format for all of my other icons that work. Why am I running into this issue upon inclusion of this one required size? How do I fix it?

I have an aggregate project that compiles several Xcode projects. All Derived Data locations are set to the default: Xcode > Settings > Locations > Advanced = Unique (the default) Aggregate Project > File > Project Settings... > Derived Data = Default Location Individual Sub Projects > File > Project Settings... > Derived Data = Default Location And yet, when I do a command line build, for each of the sub projects, a "build" folder is created alongside the sub project's xcodeproj file. Note that this project is quite old, going back many Xcode versions. I had previously had Xcode > Settings > Locations > Advanced set to "Legacy", but am shifting these old projects to use the default DerivedData location – this might be part of the problem, given that the Legacy mode always created a "build" folder next to the .xcodeproj file. Can anyone explain this? Best Wishes, Mark

After not happening to me for a few months, this issue has started hitting me again with currently %100 reproducability. If turn on VPN on my Mac then instantly the developer certificates within the keychain become untrusted. But that's not all, if VPN is then turned off the certificates do not revert to their trusted status but remain untrusted. The consequence of this is that if VPN is turned on and then a build is perform, it fails, and the only way to fix things is to delete the cert(s) from they keychain and re-install them. As a remote worker, having this happen several or even dozens of times a day is incredibly annoying and frustrating. This issue has been occurring for literally years, sometimes it occurs very often, others while its quiet for a while, and has spanned multiple versions of Xcode and Mac OS. So whatever the cause is its endemic. It doesn't just affect myself, but all the members in my development team. I'm currently using Xcode 14.1 RC 2 and Monterey but I've seen this issue occur with many versions of Xcode and Mac. (I'm using Cisco AnyConnect Secure Mobility Client). If the VPN is somehow interfering/affecting the connectivity aspect when an attempt is made by Xcode to validate the certificate, then why does it not rectify itself after turning off VPN? This is so so so so annoying. Can somebody please comment on why this happens and if there's a way to prevent it.

Hello, I have a problem with the .onMove function. I believe I have set everything up properly. However, the moving does not seem to be working correctly. When I try to move the item, it is highlighted first, as it is supposed to be. Then, while I am moving it through the list, it disappears for some reason, and at the end of the move, it comes back to its initial place. (I use iOS 16.0 minimum, so I don't have to include the EditButton(). It works the same in the edit mode tho) import SwiftUI struct Animal: Identifiable { var id = UUID() var name: String } struct ListMove: View { @State var animals = [Animal(name: "Dog"), Animal(name: "Cat"), Animal(name: "Cow"), Animal(name: "Goat"), Animal(name: "Chicken")] var body: some View { List { ForEach(animals) { animal in Text(animal.name) } .onMove(perform: move) } } func move(from source: IndexSet, to destination: Int) { animals.move(fromOffsets: source, toOffset: destination) } } #Preview { ListMove() }

Hello, I want to use flattenedClone() node for the trees in my landscape and reduce the draw call. If my texture uses a jpg file the result is good. If I use a PNG with transparency there is no draw call reduction. Can I use PNGs with transparency with the flattenedClone() ? Below is the structure I'm using: for child in scene_temp.rootNode.childNodes { let newtree = tree.clone() sum_tree.addChildNode(newtree) } let sum_tree_flat = sum_tree.flattenedClone() scene.rootNode.addChildNode(sum_tree_flat) If the tree texture contains a JPG file (diffuse) I get a draw call reduction (< 200 for my complete map) as expected (but no transparency with my leaves). If I use a PNG file, my draw calls are not reduced (> 2000) but I do have my trees with my leaves in transparency. I've tried replacing tree.clone() with tree.flattenedClone() with no results. Thanks for your help. Translated with DeepL.com (free version)

Like I said in the title, it looks like MetalTools.framework is missing or corrupted. I think I saw that the symbolic link was broken. They look like aliases in the finder, but I can't find the original. This was a problem with Ventura (using the last compatible Xcode version) and Sequoia 15.2 (Xcode 16.2). I didn't use Xcode before that. Note that none of my apps need Metal API (I don't think). I only noticed it when Xcode gave an error regarding Metal. Sorry this is so long; I hope the Terminal info will help. I don't want to reinstall Sequoia and this has been a problem since at least Ventura.

Update Xcode 16.2 but i get error Assets Validation Failed upload to Appstore,

I want to run a nap. I'm developing on my actual iPhone previously. I have been able to do this but the phone is now missing from two computers. It appears in devices and simulators on both machines.
