Hey everyone! I'm starting a new Multiplatform application with Core Data and CloudKit checked off. Before continuing I want to make sure the data is persisting between devices BUT can't figure out how to test that with the simulator. I can run the app on my Mac (under my apple account), can't run it on my phone (didn't download the beta), and when I try to log into the simulator with my Apple ID it gives me a "Verification Failed - An unknown error occurred". How do you test synced data between simulated devices???

I'm working on hooking up a Multiplatform app with CloudKit (using CoreData) and I was wondering if anyone knows any current tutorials to help me understand the process better? I was trying to wrap my head around the WWDC 2022 tutorial CoreDataCloudKitDemo but it isn't SwiftUI and I'm getting bogged down by the non-relevant code. Thanks everyone :)

I've added a package to my Mutliplatform project (Shout) that is now causing an error. When I attempt to build my program on my MacOS Ventura I get a warning "Could not find or use auto-linked library zlib" and six errors about undefined symbols from the zlib library: _deflate, _deflateEnd, _deflateInit_, _inflate, _inflateEnd, and _inflateInit_ I've added paths to my target's Build Settings under Library Search Paths and it doesn't seem to help. Has any one seen anything like this and can help me build the project? It was working with the previous version of my app on the previous stable version. I am running the beta Ventura with the new Xcode version and started a new app to move my code over in parts.

During one of the WWDC talks this year I remember hearing that when a user clicks cancel on an edit form you should show an alert warning them about discarding the changes before leaving. YET if there aren't any changes we should just exit when canceled. Looking back at that I wonder how do you know if there are no changes? Right now I load the Core Data Entity fields on my page and set them one by one on save. Is there a better way that would also make it easier to know when to leave and when to warn when canceling? Are there any examples of this? Thanks everyone.

I'm restarting my app using CoreData and CloudKit and want to implement testing before I get too far and it becomes unmanageable. Is there a good tutorial anyone has found for testing when using SwiftUI (macOS and iOS but not storyboards). Thanks. It seems overwhelming right now and I don't know where to start. :)

Hi, I'm creating a SwiftUI MacOS app with a NavigationSplitView consisting of a Sidebar and Detail. It works great; however, whenever I ran the app the sidebar is hidden. As a user I can easily click the button or menu option to bring it back BUT it's frustrating to do AND I need to test the app now. Is there a way to have it open by default when running the app or, at least, programmatically so I can set it as a user default? And/Or a way to make it visible when running UITests? Thanks

I am currently running Xcode Version 14.0 beta (14A5228q) creating a Multiplatform app. I wanted to include a LaunchScreen so added a Launch Screen Storyboard to my project. To the the app to see it I went under Target for my app, General, and under App Icons and Launch Screen I set the Launch Screen File to my storyboard. This works perfectly when I run the app on iOS; however, when I run it on macOS I get an error:Launch Screen.storyboard error build: iOS storyboards do not support target device type "Mac". I see there's no way to differentiate between macOS and iOS with the file and there's only one target. Does anyone know a way to make the storyboard only launch when running the iOS app (and iPadOS) and not be seen when running macOS? Thanks

Yesterday I had issues with my CoreData database for my Multiplatform app which resulted in changes to the schema. I reset the CloudKit version and, on the iOS simulator, had to delete my app and run the code again to get it to work. My issue is with the macOS target. I'm getting the same fatalError (Fatal error: Unresolved error Error Domain=NSCocoaErrorDomain Code=134140 "Persistent store migration failed, missing mapping model.") when running the macOS app but I can't figure out how to delete it so I can run it fresh like I did with the iOS version. I've found where the application is created (in the Debug directory ultimately within my app's Build directory) and removed them all but when run the newly created application has the same error. Should I move up the directory structure and remove the entire app directory within Xcode/DerivedData or is there another way? Wanted an answer before I do something I can't go back from :) Thanks, Kyra

I'm creating a multiplatform app on the Beta Xcode and have just migrated code over to set an image from the photo library. When I run the app on my iPad (with beta OS) it works fine. When running the same code on the iOS simulator I end up with a blank view without any images. There are a lot of errors outputted to the console starting with: 2022-07-12 09:59:46.037994-0700 MyAppName[10647:2080202] [UIFocus] TtGC7SwiftUI14_UIHostingViewVS_7AnyView implements focusItemsInRect: - caching for linear focus movement is limited as long as this view is on screen. objc[10647]: Class _EXRunningExtension is implemented in both myPathway/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/ExtensionFoundation.framework/ExtensionFoundation (0x7ff864a43f90) and myPathway/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/ExtensionFoundation.framework/ExtensionFoundation (0x1231e5d48).

Hey, I'm coding my app in the Xcode Beta 2 and am attempting to access the HKHealthStore() to add a HKCategorySample. When I run the app and attempt to add the sample I get the following error: Error Domain=com.apple.healthkit Code=4 "Missing com.apple.developer.healthkit entitlement." UserInfo={NSLocalizedDescription=Missing com.apple.developer.healthkit entitlement.} When I make sure to requestAuthorization before running the code I get a different error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSHealthShareUsageDescription must be set in the app's Info.plist in order to request read authorization for the following types: HKCategoryTypeIdentifierMindfulSession' I'm assuming I need to add to my Info.plist but am unable to figure out how. If I go to my project or project's target and access Build Settings I see the following image: But am unable to edit it. I assuming I want to add NSHealthShareUsageDescription with a String explanation for why I want access but anything I find online is for an older Xcode so I don't know how to do it. Any help to get this working would be really appreciated. Thank you

I have a multiplatform app that I'm coding that uses HealthKit. To get it working I needed to add a custom entitlement to the entitlements file. Specifically "application-identifier". See this solved question for more information: https://developer.apple.com/forums/thread/713829 Now I can only run the app on my simulators and NOT on my phone or Mac as the automatic signing is failing Provisioning profile "iOS Team Provisioning Profile: myName.AppName" doesn't match the entitlements file's value for the application-identifier entitlement. It says to submit a bug report: Automatic signing failed. Xcode failed to provision this target. Please file a bug report at <https://feedbackassistant.apple.com> and include the Update Signing report from the Report navigator. Which I did FB11512832, but is there something I can do to fix this or is it just a wait and see? Error image:

Hey, During a developer Q&A today I was referred to a "Sundae shop" (the ice cream) sample code from, I think it was, WWDC 2020. Does anyone know where I can find it? I want it mainly for ObservedObject updates for my view from an async model. Thanks :)

I'm attempting to figure out how to display a message to my users when some asynchronous code takes some time to run. So far I've used a sample I found online to create a popup banner and tied the message together using an ObservedObject of the async method on my view and Publishing the values. My sample code project is on a public GitHub repository here. https://github.com/SimplyKyra/CodeAttempts Right now I have an issue as when I set the variables in the async method I'm getting the following error: Publishing changes from background threads is not allowed; make sure to publish values from the main thread (via operators like receive(on:)) on model updates. Solutions online seem to fix this issue by updating the value on the @mainActor thread but I want these methods to run asynchronously AND update the user on what's happening. What's the best way to update my variables from this location?

Hi. I’m developing a multiplatform app for both iOS and macOS and was wondering if there’s any way to display an SVG file in the swiftUI view. I’ve seen ways online once you put the image in the assets file but this will be dynamic coming from outside the program. I just want to display and maybe rotate it but nothing more complicated than that. thanks

I'm developing a Multiplatform app that uses CloudKit to sync the CoreData between the user's devices. At this time they don't share data between users. I have a single password field on a single Entity and was wondering if there was a simple way to encrypt just this field. I see in CoreData there's a checkbox labelled "Allows Cloud Encryption"... does checking that off magically encrypt it. I checked it off and nothing seemed to change so I unchecked it for now... is there something else I needed to do? And, most importantly, will it work with CloudKit?
