how to fix swift preview on real device no showing

Example: I have a state var curHighScore declared in ContentView. I select it, right click and select "Find Selected Symbol in Workspace" The result is : 1 resul in 1 file, i.e. the line of declaration of the var But obviously, the same var is used at line #102: How come this occurence is not found by the search command. Such happens every now and then. Is there something I am missing ? What is causing this ? Thanks for your help.

Like the title says, I'll commit some changes no problem with my Git name and email displayed properly, then work for a while longer and when use the integrate menu to stage and commit I find the git name/email are empty. My credentials are properly entered in settings. The only fix i've found is quitting and restarting. Any less frustrating option?

I have the 'warnings as errors' policy set to Yes for Apple Clang and Swift compiler. As far as I know, there is no way to make exceptions to the warning policies from Swift compiler (correct me if I am wrong), what about Clang warning policies, specifically when it comes to header files from 3rd party pods? They don't show up on the Compile Sources so I can't apply flags such as -Wno-error=deprecated to them. Adding #pragma GCC... to them won't help as a fresh pod install will wipe the #pragma statements out. Is there a way to exclude the header files from pods from getting the warning policies from Clang so I won't see errors from them when compiling Clang modules that's a part of the build process?

I have a warning on my AR app Virtual Tags that since July does not show its camera information telling: "ARCL.SceneLocationView implements focusItemsInRect: - caching for linear focus movement is limited as long as this view is on screen." I tried inserting the function, but documentation does not explain what it should return and how to generate it. Is someone able to help me? Thanks,

We’re developing an iPad application that visualizes 2D and 3D building floor plans, including a mesh network of nodes that control lighting and climate. The node count ranges from 1,000 to 15,000. We’re using SceneKit to dynamically render the floor plan and node mesh on an iPad 10th generation running iPadOS 18.3. While the core visualization works, we are experiencing significant performance degradation as the node count increases. Specifically: At 750–1,000 nodes, UI responsiveness noticeably declines. At 2,000 nodes, navigating the floor plan becomes nearly unusable. We attempted to optimize performance with a Geometric Pool algorithm, but the impact was minimal. Strangely, the same iPad handles 30,000+ 3D objects effortlessly when using Unity or Unreal Engine, raising the question of whether SceneKit may not be optimized for this scale. Our questions: Is SceneKit suitable for visualizing such large node counts, or are we hitting an inherent limitation of the framework? Are there best practices or optimization techniques for SceneKit that we might be missing? Should we consider a hybrid approach or fully transition to a different 3D engine for this use case? We’ve attached a code sample below demonstrating the issue. Any insights, suggestions, or experiences would be greatly appreciated! ContentView.swift

I am using Xcode 15.2. I am loading a URL in a WKWebView, but a hand cursor appears above the web view. Scrolling up and down does not work. I tried adjusting the scroll bounds and isUserInteractionEnabled, but the hand cursor is still visible. How can I fix this?

When Xcode 16.2 connects iPad to real machine debugging using the view in the picture box, the mac will be stuck directly, the computer cursor will disappear, and the computer cannot do any operation

Hi iOS peeps ! Was just wondering if anyone has had this issue before with String Catalogs. I have an iOS project where I am using String Catalogs for localisation ( the project is split up into multiple local swift packages with each project having its own Localizable.xcstrings ) and the app currently only supports en as the base and en-US for US localisation During the build process however some of the swift packages only produce the en-US localisation and is missing the en default localisation in the binary. Having a look at the build log for some xcstringstool will only produce one set of Localizable.strings (en-US.lproj) instead of (en.lproj and en-US.proj) I haven't been able to find much documentation from Apple on xcstringstool as well / not sure where to find more info about this

My swiftUI project has started to constantly display "Cannot find 'symbol' in scope" errors in code i haven't touched, and the project still compiles fine. Neither cleaning build folder or compiling fix the errors, but if I right click the symbol, select "jump to definition" it will find it without problem and then when I return to the original file the error will be cleared. What can I do to stop these from happening?

Hello, Is anyone experiencing devices on OS 17 disconnecting from Xcode 15 and 16 Beta? I remember there were a lot of past conversations around the time when iOS 17 released but it seems to still be happening even after using Xcode 16 beta. Re-pairing devices and rebooting the hosts appear to fix it temporarily. I discovered that killing the remoted process also allows xcode to reconnect to the devices. Using Xcode 16's devicectl also doesn't work. I have my devices connected to a USB Hub and to multiple devices. The odd thing is I have iOS 16 devices connected and those don't disconnect. I believe iOS 17 introduced a new coredevice stack to connect but has anyone found a fix for it or have any recommendations? TN3158 isn't relevant in my situation because VPN and Packet filtering is not in use and I filed feedback with Apple but they have't responded in a long time.

Hi all, reposting from here: https://unix.stackexchange.com/questions/789849/xattr-c-not-removing-com-apple-finderinfo-attribute I was trying to build my Xcode project, but ran into the error "resource fork, Finder information, or similar detritus not allowed." I was following the solutions from this stack exchange post, but xattr seems to not be working as expected. Basically, running xattr -cr . on my project directory successfully removes all xattrs except for com.apple.FinderInfo, which persists on all .xcodeproj and .xcworkspace files. I've tried everything under the sun, from xattr -d to sudo to dot_clean to tar to rsync and nothing can remove it. Is this just some kind of immortal attribute? It's preventing me from building my project. I'm at a loss here, this is my senior thesis project.

Since updating Xcode to 16.2 I get the following message when attempting to build the project. SWIFT_VERSION '' is unsupported, supported versions are: 4.0, 4.2, 5.0, 6.0. The issue I have is that the project is pure objective-c. There is zero Swift code in the project so am struggling to understand why this error is being generated. Welcome assistance. Graeme

I tried to monitor the device's network status with Network framework code below. let networkMonitor = NWPathMonitor(requiredInterfaceType: .cellular) networkMonitor.pathUpdateHandler = { [weak self] path in     if path.status == .satisfied {         print("Cellular Satisfied")     } else {         print("Cellular Unsatisfied")     } } When I run the app in my iPhone(iOS 15.5) and turn cellular on/off, iPhone suddenly loses connection with XCode.

Hello, I have tried to add Sign in with Apple to my application, and I get to the point where the app asks which AppleID to use and does succesfull facial recognition, but does not return failed or successful validation - the loading animation does not end and just keeps going. I have tried to create the sertificates and provision profiles again. I have also set the entitlements file Apple access level to Default. I don't understand what is going wrong here. Can the certificates be in wrong place? Is something wrong with the code?

I can't add my iPhone to my Apple Developer team, even though my iPhone is properly connected to my Mac.

We are encountering a persistent code signing error with in-app purchase capabilities in our iOS app. Despite having the com.apple.developer.in-app-purchase entitlement properly configured in the app's entitlements file and the In-App Purchase capability enabled in both Xcode and the App ID configuration in the Apple Developer Portal, we continue to receive the error: "The provisioning profile 'iOS Team Provisioning Profile: does not include the com.apple.developer.in-app-purchase entitlement." We have attempted multiple solutions including: Regenerating provisioning profiles Cleaning and rebuilding the project Switching between automatic and manual signing Removing and re-adding the in-app purchase capability Verifying all entitlements and capabilities configurations The error persists despite the entitlement being correctly set in the entitlements file and the capability being enabled in the App ID. This appears to be an issue with how the provisioning profile is being generated or how the entitlement is being recognized by Xcode's code signing system.

I have written a small iOS app that I run as a MacOS app using the build target "My Mac (Designed for iPad)". It runs fine, however I cannot find where the app itself is installed on my system. When running the app multiple times I see that a number is appended to the title of my app is incremented indicating that old versions of the app are still installed somewhere. Where are they located on my system? Many thanks for the help!

In the test plan settings, it's possible to select an .xcappdata bundle for a set of tests: I failed to find any documentation about it in the context of macOS apps testing. What I'm trying to achieve is having a sandboxed app container (/Users/{user}/Library/Containers/{bundle-id)/Data/) replaced before running a test suite. Is it something possible to achieve using the latest Xcode? What should be the .xcappdata structure to make it work on macOS?
