Hello, In Xcode 15 beta 3, if a project embedded a Swift package (no matter static or dynamic), and the package has its own dependencies, the linker will always emit following warning: ld: warning: duplicate -rpath '/Users/.../Library/Developer/Xcode/DerivedData/MyApp.../Build/Products/Debug-iphonesimulator/PackageFrameworks' ignored The warning is not appeared on beta 2 and beta 1. Reproduce Steps [1] Create a new iOS project in Xcode 15 beta 3 [2] Create a new Swift package MyLibrary, and add any dependency in the Package.swift. Example: // swift-tools-version: 5.9 import PackageDescription let package = Package( name: "MyLibrary", platforms: [.iOS(.v16)], products: [ .library(name: "MyLibrary", targets: ["MyLibrary"]), ], dependencies: [ // 👀 Add any dependency to this package. // Here I use "Version" which is a simple pure swift package: .package(url: "https://github.com/mxcl/Version.git", .upToNextMajor(from: "2.0.0")), ], targets: [ .target(name: "MyLibrary", dependencies: ["Version",]), ] ) [3] In the project page, embed MyLibrary into the iOS app target. [4] Build the project. It will succeed but with link warnings. In addition, if you create a dynamic framework and embed MyLibrary, the warnings also reproduce. And this is only a simple case. In my real project, the linker will also emit a lot of warnings like this: ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$__TtP10SPConfetti18SPConfettiDelegate_ ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$__TtP10SPConfetti18SPConfettiDelegate_ ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionTaskDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDataDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDownloadDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSObject ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionTaskDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDataDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDownloadDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSObject

I have extracted a part of my app into a framework, which I have been building as a static library (mach-o type=static library). This has been inflating the app size, as the framework has been statically linked into both app & widget targets. I have switched the framework to dynamic library, set to build it as a mergeable library, set the app targets to 'create merged library: automatic'. Unfortunately, my release builds now fail with "unknown option: -make_mergeable" in Xcode 15 beta 8. This happens in "Link " step during a framework build. Debug builds work OK. How can I fix this?

Hi! I've been dealing with mergeable libraries quite some time. However I can't achieve the following scenario: I have 2 xcframeworks A and B that are merged as part of a third xcframework called C. And my app needs to import something from A and B. As per the documentation we have to remove the references from A and B from the final app and replace it with C. If I work on the same xcodepoj it works like a charm (maybe because of caches), but if I try to compile C as a separate XCFramework and distribute it as a packed library, the app is not able to resolve the symbols to A and B classes. This C xcframework is compiled with BUILD_LIBRARY_FOR_DISTRIBUTION se to true and if I check its swiftinterface files it is not declaring the symbols from A and B. However the size of the binary seems to have A and B. Is there any way to export A and B symbols as part of C's swiftinterface? If I add @_exported, it is forcing me to declare the import of A and B wherever I use them and therefore I'm going to have duplicated symbols Thanks!

I try to create a Mergeable Framework using Command like this. xcodebuild archive \ -scheme Mergeable \ -configuration Release \ -destination 'generic/platform=iOS' \ -archivePath './build/Mergeable.framework-iphoneos.xcarchive' \ SKIP_INSTALL=NO \ MERGED_BINARY_TYPE=MANUAL \ MERGEABLE_LIBRARY=YES \ BUILD_LIBRARIES_FOR_DISTRIBUTION=YES But it seems that I can't find any way to create a Mergeable framework using xcodebuild. Do we have another option to indicate the xcodebuild create a Mergeab,e Framework Thanks, Ben.Dang

Hi everyone, I use new feature mergeable libraries in XCode 15 beta 2 to create xcframework. Follow the instruction of https://developer.apple.com/documentation/xcode/configuring-your-project-to-use-mergeable-libraries. I can create the megrable framework for devices (ios-arm64) and it can use in another project. But for the megrable framework for simulators (ios-arm64_x86_64-simulator). It can't use this framework for another project and XCode throw the error: Showing Recent Messages arm64-apple-ios-simulator.private.swiftinterface:6:8: No such module 'Framework3' 'Framework3' is linker framework, inspite of it already have this framework in the "ReexportedBinaries" of the mergeble framework. Structure for mergeable framework: - Mergalble.framework --- ReexportedBinaries ------- Framework3.framework It is have the same issue with the xcframework. So, is it the issue with XCode 15 beta for mergeable framework of simulator and xcframework? Do we have to add any specifice agrument for create xcframework with the mergeable libraries? Best Regards, Hula Nguyen

I have built a mergeable framework for distribution using Xcode 15. But when I try to merge it into an App target using -merge_framework in "Other linker flags", I get the error "Unknown argument: '-merge_framework'"? I'm not sure if the new linker is being used, but I assumed it would be used by default and I'm not sure of a way to enable it if not.

I'm currently creating the 3 xcframeworks A, B, C and a Group xcframework (configured to manual) which groups them, let's call it D. A, B and C are properly configured with the following settings: MAKE_MERGEABLE = YES; MERGEABLE_LIBRARY = YES; OTHER_LDFLAGS = ( "-ObjC", ); The problem comes when I try to initialise a UIStoryboard via code, it fails because it can't be found. let storyboard = UIStoryboard(name: "MyStoryboard", bundle: Bundle(for: NSClassFromString("A.Class")!)) The error it is raising is: Could not find a storyboard named 'MyStoryboard' in bundle NSBundle </some_path/Sample.app> Also, if I try to search for a specific file (such as a json) with the same structure Bundle(for: NSClassFromString("A.Class")!) it is not able to get any file. Points to note Xcode version 15 beta 1. Bundle(for: NSClassFromString("A.Class")!) returns a valid bundle path

Hello, I'm Software Engineer and my work is developing SDK. I'm on developing 1 Swift Package for general logic and 1 SDK (Xcode Framework Project) for business logic. (SDK depends on Swift Package) Until now, I merge them with @_implementationOnly. And I want to migrate to MAKE_MERGEABLE. Can I mark Swift Package Dependency as MAKE_MERGEABLE on SDK Xcode Framework Project? Or can I mark Swift Package MAKE_MERGEABLE on Package.swift? Or I can't make Swift Package MAKE_MERGEABLE?
