Persistent Xcode validation errors
We recently updated the codebase of our existing iOS application to improve compatibility with the latest versions of iOS. For several months, our attempts to deploy the updated application to TestFlight for testing and validation have consistently failed due to four recurring Xcode validation errors. Please see the attached document X-Code Validation Errors.txt for details on these errors. Our application is developed using Visual Studio 2022 for PC with the .NET MAUI framework, as Microsoft no longer supports Visual Studio for Mac. After a successful build and testing using a virtual iPhone interface, Visual Studio connects remotely to the MacBook (Mac OS 15.1) sending the necessary project files that automatically triggers the Xcode (16.1) validation to begin. We have made numerous edits to both the plist.info and the project file in an attempt to resolve the validation errors with little to no success. We are confident that is a configuration mismatch between what the plist say

XCode 26.0.1/iOS 26 unable to mark class as ObservableObject
Started a new X-Code Project after updating to 26.0.1 and realized that I get an error when trying to mark a class as ObservableObject => Class XYZ does not conform to Protocol 'ObservableObject'. Strange behaviour, because at old projects the code is working even though the build options are the same and other settings like iOS version in Target are the same. There must be something chaged under the hood of XCode? I have to import Combine now, before I could write my class, e.g. CoreData Datamanager: ObservableObject only using CoreData.

Reply to How To Get Assembler Listing Of C++ Program In Xcode
Answering a slightly different question:In Xcode 7.1, select your C or Objective C source code file in the file inspector; then, in Xcode's Product menu, select Perform Action > Assemble yourSourceFile.mYou may have to play with Architectures in the selected Target's Build settings to select the 32 or 64 bit ISA you want to see.Also, with Xcode 7.x installed, from the OSX Terminal command-line, you could try:xcrun -sdk macosx swiftc -emit-assembly yourSourceFile.swiftorclang -S yourSourceFile.c

Reply to multiple problems with x code, is it the iMac?
Hi ClaudeAll versions of X code from July last year up to 9.3Memory 8 GB 1867 MHz DDR3Storage Available: 682.01 GB (682,014,576,640 bytes)Capacity: 998.98 GB (998,982,549,504 bytes)It is a standard late 2015 iMac. I have spoken to several developers about this and none of them think that memory would be an issue, however if it is then I'm stuck as this model is not upgradeable.ThanksGeoff

xcode previews keeps loading its self on iphone 12
First, I am not a developer but was directed here by the regular apple forum for help. I was wondering if anyone knows how/why x-code previews keeps installing itself on my iphone 12 pro max. I am unable to directly delete it, only delete from the home screen but remains in the App Library. Recently I noticed it would go away completely on a reboot but eventually I see it back on my phone just sitting there taunting me with its unknown origins and intentions. Lol. From what I kind of understand is that it is app to let you test x-code apps?? Why in the world is it here. Please tell me something that is not that I am hacked and or just paranoid and how do I rid myself of it. Help?

Reply to Constraints
Claude31’s first answer was about what I do (use an IBOutlet for the constraint, and change it in code).I don’t recommend anything using model names, however. You would have to update your iPhone X code for iPhone XS, for example. Better is to figure out why you’re using the different constraint. Is it because there are non-zero safe insets? Is it because the screen is wider than 16 * 9? Make your decision based on those factors, and you’re more likely to be safe for the future.

xCode 8 vs xCode 7
Hi, I have a game developed with Unity3D and, before I update the xCode 7 to xCode 8, I can't validate and upload my app to AppleStore, have any of you had this problem too?, If yes, do you know how can I fix it? Do I need to try to uninstal xCode 8?

Reply to Watch Connectivity - WCSessionDelegate methods not called (simulator)
I'm having exatly the same problem, but with an actual Watch and iPhone (ie not simulator). Interestingly, the Apple sample code for WCSession, Potloc, had the same problem in a beta and/or Xcode version, then worked OK in another, and now fails to complie under the latest Xcode beta. Unfortunately I have two development environments that have had different versions of Xcode and OS X at various times combined with the iOS 9 and OS2 betas, so I haven't kept track of what version of Potloc worked in which specific environment.This is very frustrating.Regards,Michael

Reply to NSPersistentCloudKitContainer with public database doesn't work and is poorly documented
I've had a similar problem trying to get the boiler plate app code that is generated by Xcode for a new project to run correctly. The App (which worked in Xcode12.x) not tries to connect to iCloud and appears to have authentication problems... it generates failed to sync users messages when it tried to connect on a simulator that has a valid user signed in. Steps to repeat: Start a new project in Xcode 12.x with CloudKit and CoreData enabled Enable the remote notifications and iCloud capabilities, selecting CloudKit and creating a new container Make a couple of changes to the ContentView to fix the error in the generated code (needs to include a PaginationView and wrap the toolbar elements in ToolbarItem Views) Run on two signed-in simulators and observe the synchronisation working (noting that perhaps now you need to close the app and restart it for the sync to work, instead of the old minimise refresh trick) Close Xcode 12.x and start t

Distribution with XCode
Hello All,Sorry i am a noob at this, but im finding it quite difficult to figure out the correct accounts and licences i need to achieve this. Basically, im creating apps where i need to distibute to clients via email on a fairly regular basis. I dont want to upload anything to the apple store, i need everything to be internal and only accessable to who i've sent it to. I was recently sent a demo, where all i needed to do was click the link in the email (using the ipad) and the app began installing on its own. This is perfect as my clients arnt partiuclarly tech savvy and need a very simple way to get the apps on their devices. I dont want to use testflight becuase its an extra step that could confuse matters. I just want a link that can be downloaded from an email and easily installed. I would really appreciate it if anybody could tell me what i need to acheive this, and if X-code can be used for it?Thanks
