I'm building an iOS app using Xcode, and I frequently modify code within a package. To do this, I drag and drop a locally cloned version of the package into my project as a local package. However, when working across multiple branches of my app, I need different versions of the package as well. To achieve this, I use Git worktrees to create branch-specific copies of the package. Unfortunately, when I drag and drop these worktree copies into Xcode, the IDE doesn't seem to recognize them. Could you kindly guide me on resolving this?

I have a build, but Distribution won't add it because it doesn't see encryption info in the Info.plist file, but that's hidden in Xcode. How do I find/update it?

We have a relatively big iOS-only project with around 80 build targets from swift packages (local features and external project dependencies) and Xcode 15.4 (originally, migrated to 16.0). Project compiles and runs great, but xcodebuild archive will fail 4 out of 5 tries with this: ld: file cannot be open()ed, errno=2 path=/opt/builds/fLLyxmhG/0/myapp/Build/Intermediates.noindex/ArchiveIntermediates/myapp (Development Flow)/BuildProductsPath/Debug-iphonesimulator/Account.o in '/opt/builds/fLLyxmhG/0/myapp/Build/Intermediates.noindex/ArchiveIntermediates/myapp (Development Flow)/BuildProductsPath/Debug-iphonesimulator/Account.o' Where Account.o is an end product of one of our feature packages linking to an .app itself. This error is not tied to this concrete package/product (which should be compiling almost last relative to build graph) and could appear mid-build in between our service layer packages. It seems (and is approved by Xcode timeline for .app archive log) that module dependency is compiled later than module itself and linker just cant find its dependency object files. The scheme is: Module A (dependency itself) Module B (needs module A) And with build order expected (???) to be A (first) -> B we're getting the B -> A. Error appears only when archiving for Debug configuration, archiving the same end-target with Release configuration results in stable passes 10 out of 10 tries. Setting identical parameters in Build Settings tab for both configurations of a target is not giving any effect. Our current fix is choosing Manual order in scheme Build order setting. Everything works as expected, but i guess it's not optimal 🤧 Sadly can't provide test project, but anything else — welcome.

The app gets stuck after login on an iOS 18 device. It works in Xcode, but the simulator shows the following console error: IntegrationApp(769,0x1f0094c00) malloc: xzm: failed to initialize deferred reclamation buffer (46).

I have a save button: Button(action: { saveTapped() }) { Label("Save", systemImage: wasSaved ? "checkmark" : "square.and.arrow.down") } .contentTransition(.symbolEffect(.replace)) .disabled(wasSaved) Now, I created a new custom icon and added it into the assets catalogue: "custom.square.and.arrow.down.badge.checkmark" for when the wasSaved state is true. The issue I am facing is that to use it I need to use the method of Label with image:, while to use the non custom symbol, I need to use systemImage:. So how is it possible to transition between the two?

I am writing to express my deep dissatisfaction with a recent experience involving your services. I have discovered that I have been charged twice for the same product or service, which I find unacceptable. Additionally, I have not received the necessary support to resolve this issue, and the product or service in question does not function as it should. The treatment I have received has been neglectful and far below the standards I expect from a company that prides itself on providing quality service. This situation has not only shaken my confidence in your services but has also caused significant frustration as a customer. I demand an immediate resolution to this issue, including a refund for the duplicate charge and assurance that the purchased product or service will work as promised. If I do not receive a satisfactory response, I will be forced to take further action to protect my rights as a consumer. I look forward to your prompt response to resolve this matter.

Hello, I recently switched my app from flutter which was using sqlite3 database. I would like to migrate my existing users to SwiftData. The issue is I do not know where to start in finding the database for the current users, reading the data and inserting into the SwiftData schema. I tried searching but not clear on how to proceed. Any help pointing in the right direction would be great. Thanks.

Xcode crash report

Hi, I work on a iOS application which includes several local swift packages containing modularised code. Each of those local swift packages has a test target defined in their respective Package.swift, and when opening a local package folder standalone in Xcode, then the tests run without issues. However I would like in the main app's test plan to add the local package test targets and have them all run together when the main app's default test plan is run. Xcode allows me to select local package test targets within the main app's test plan (also within Test portion of the main app's scheme), however attempting to build for testing throws a "Module '…' was not compiled for testing". Any ideas on how to achieve this goal (run local package tests in conjunction with main app's tests) and avoid that error? Thanks Peter

Hi, I have a library for my iOS Apps. It uses among other things the Combine framework, Core Location and OSLog. I manage the library using the Swift Package Manager (SPM) and usually build via XCode, which works fine. However for CI I would like to build everything from the terminal. So I do call 'swift build' on the terminal. This produces errors such as: 'PassthroughSubject' is only available in macOS 10.15 or newer 'os_log(:dso:log::_:)' is only available in macOS 10.14 or newer 'eraseToAnyPublisher()' is only available in macOS 10.15 or newer 'authorizedWhenInUse' is unavailable in macOS 'AnyPublisher' is only available in macOS 10.15 or newer 'showsBackgroundLocationIndicator' is unavailable in macOS ... These are all from the used frameworks. However, I do not care on which version of macOS, for example, PassthroughSubject is only available at, since the library is iOS only. Too make sure of that I added "platforms: [.iOS(.v14)]" to my Package.swift and thought this would be sufficient, so the project does not get build for macOS. Can anyone please tell me or give me a hint on what I am getting wrong here?

Hi! I'm trying to create a target application that depends on multiple targets that all use the same Swift package that has xcframework binaryTarget. Each component can be successfully assembled individually, but when I try to create a core application that depends on these components, I get an error message on Prepare build stage: Multiple commands produce '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/Build/Products/Debug/Frameworks/<FW_NAME>.framework/Versions/A' Target '<COMPONENT1>' has copy command from '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/SourcePackages/artifacts/.../<FW_NAME>/<FW_NAME>.xcframework/macos-arm64_x86_64/<FW_NAME>.framework' to '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/Build/Products/Debug/Frameworks/<FW_NAME>.framework' Target '<COMPONENT2>' has copy command from '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/SourcePackages/artifacts/.../<FW_NAME>/<FW_NAME>.xcframework/macos-arm64_x86_64/<FW_NAME>.framework' to '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/Build/Products/Debug/Frameworks/<FW_NAME>.framework' – where <FW_NAME> is a name of the xcframework which is the binaryTarget in the Swift package. Could someone please explain to me if it is even possible to use xcframeworks packaged in Swift packages in such cases, and if so, how to do it correctly?

When user enters in a textfield, is the input of textfield gets stored in a String ? If yes, then String in swift being immutable, as user keeps on typing does new memory for storing that text gets allocated with each key stroke ? And when we read users input by using delegate method textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) from textfield.text, we get users input in a String. Is it same storage as used by textfield for storing the user input on key stroke or is it some other storage with copy of the user's input in it? Or is UItextfield using a diffrent data structure (buffer) for storing the user input and when we do textfield.text, it gives a copy of data stored in original buffer?

When i create a intance of swift String : Let str = String ("Hello") As swift String are immutable, and when we mutate the value of these like: str = "Hello world ......." // 200 characters Swift should internally allocate new memory and copy the content to that buffer for update . But when i checked the addresses of original and modified str, both are same? Can you help me understand how this allocation and mutation working internally in swift String?

Hi everyone, I’m planning to develop a cross-platform PDF viewer app for iOS and macOS that will read PDFs from local storage and cloud services (Google Drive, iCloud, WorkDrive, etc.). The app should be read-only and display both the PDF content and its metadata (author, title, creation date, etc.). Key Features: View PDFs: Local and remote (cloud storage integration). Display metadata: Title, author, page count, etc. Cloud integration: Google Drive, iCloud, Zoho WorkDrive, etc. Read-only mode: No editing features, just viewing. Questions: Xcode Template: Should I use the Document App or Generic App template for this? PDF Metadata: Any built-in libraries for extracting PDF metadata in a read-only app? Performance: Any advice or documentation on handling large PDFs or cloud fetching efficiently? Thanks in advance for any advice or resources!

The problem is that when building the application with Debug mode on Xcode 16.1, the dSYM files fail to upload to Crashlytics. It worked in latest Xcode 15 version. The workaround is to disable Debug Dylib Support in the target's Build Settings. However, this causes SwiftUI previews to stop working. Reproducing the issue Set ENABLE_DEBUG_DYLIB=YES for build options Build the application in Xcode 16.1 Firebase SDK Version 11.4.0 Xcode Version 16.1 Installation Method Swift Package Manager Firebase Version 11.5.0 Relevant Log Output warning: (arm64) /Users/dustin/Library/Developer/Xcode/DerivedData/MyAppName-cicejndcecececfe/Build/Products/Debug-iphonesimulator/MyAppName.app/ MyAppName empty dSYM file detected, dSYM was created with an executable with no debug info. The warning seems like is from XCode/lldb compiler rather than Crashlytics (https://lldb.llvm.org/cpp_reference/SymbolFileDWARF_8cpp_source.html line655). This is probably something on Apple side, Crashlytics only consumes dSYM which is generated from Xcode. (ref:https://github.com/firebase/firebase-ios-sdk/issues/14054#issuecomment-2477235548) This is related to: Firebase Issue

In below Swift code , is there any possiblities of failure of Unmanaged.passRetain and Unmanaged.takeRetain calls ? // can below call fail (constructor returns nil due to OS or language error) and do i need to do explicit error handling here? let str = TWSwiftString(pnew) // Increasing RC by 1 // can below call fail (assuming str is valid) and do i need to do explicit error handling for the same ? let ptr:UnsafeMutableRawPointer? = Unmanaged.passRetained(str).toOpaque() // decrease RC by 1 // can below call fail (assuming ptr is valid) ? and do i need to do explicit error handling Unmanaged<TWSwiftString>.fromOpaque(pStringptr).release()

We are currently building an app in Swift, reusing an internal C++ backend used in other platforms ( Linux/Windows/Mac ). Current state of the project: App W - ( Swift App ) Package X - Swift Package Y.xcframework - Binary Target (ios-arm64 and ios-arm64-simulator) Z.framework Z - (C++ Backend as a library) Dynamic Library Headers - Library header files Frameworks (Folder) - Required .dylib’s for Z ( libA.dylib (Dependency of Z) [ 58 of them ] libB.dylib (Runtime dependency of python) [ 123 of them ] data - Supporting binary files for Z conf - Supporting configuration files, both text and binary. for Z python - Supporting .py scripts C.py D.py Z.framework ( C++ ) contains 182 Dynamic Libraries. Goal: Validate the app for distribution with the Apple Store validation tool. Learning when trying to solve the problem: A framework can contain only one dynamic library (e.g. .dylib ) A framework cannot have nested frameworks within a Frameworks folder Certain file types within a framework are not treated as resource files (e.g. .py files) Possible solutions Allow to have nested Frameworks in Z.framework. It’s currently not allowed Link 182 dynamic libraries into the project via SPM Problem: Some of the libraries need to dynamically loaded at runtime (related to the python runtime) Making the libraries static adds significantly technical challenges to the Z.framework. Other questions: What’s the best way to achieve this

Hi all, Background: I am working as a library developer and would like to enable Swift C++ interoperability in our library. Our library supports both CocoaPods and SPM. Question: I would like to know whether it is possible to avoid breaking changes bring to the library users after enabling Swift C++ interoperability. In my experiment, all apps and packages depend on the library needs to enable interoperability in Xcode or package manage tools, otherwise the source code cannot be complied. I am wondering is there any ways to bypass this? For example, is there a way to only enable Swift C++ interoperability only in our libraries?

Hej hej tl;dr. I have problems building a Playground App using Xcode Cloud and I created a reference repository to reproduce this. Did anyone try this before and succeeded? Maybe you have a hint about what's going wrong here. Initial Failure I followed the documentation for Building Swift packages and Swift Playgrounds app projects with Xcode Cloud and I have always run into the following error message: ❌ Code Signing Exporting for App Store Distribution failed.

Hello team, We recently found a EXC_BAD_ACCESS crash when using UIHostingControllers on a SPM local Package in our application. This is happening from time to time when we run the app on simulators using Debug configurations. Also, this issue is consistent when we run application tests, there is something weird that we found after making a research... If we disable app test target and only keep packages tests, the crash is not happening, but as soon as we re-enable the app test target from the test suite the crash returns. This is the full error message: Thread 1: EXC_BAD_ACCESS (code=1, address=0xbad4017) A bad access to memory terminated the process. Is this s known issue? We've been performing explorations for some days and couldn't find any real solution for this. A basic call on UIHostingController inside of a SPM local Package is enough to make the app crash, nothing custom being done: UIHostingController(rootView: MyView())
