I have the XCode Version 15.3 (15E204a). When I try to compile my application, the following errors occur: Undefined symbol: _GDTCCTConstructiOSClientInfo Undefined symbol: _GDTCCTNetworkConnectionInfoNetworkMobileSubtype Linker command failed with exit code 1 (use -v to see invocation) Any solution to fix this issue?

I am building a unit test. The target of this unit test is my framework. My framework linked with couple of static libraries. When the test is running in simulator with host app it works fine. But when I try to test without host app I get following error from linker. PS: My test's xcconfig is similar to the host app's, and I can build the host app successfully. Undefined symbols for architecture arm64: "__mh_execute_header", referenced from: So what is __mh_execute_header and what framework/library it is defined in? Thanks for any help!

This is a major issue. My iPad app is crashing in the App Store. In order to fix it, I found a post that recommended making the framework optional. I did so. Now I can't compile on simulator and besides, it did not fix the iPad App Store crash. ld: framework 'JournalingSuggestions' not found

With XCode 14 and below, our macOS application is building and running fine. The application depends on some third-party .dylibs and also a couple of .frameworks that we make in-house, all of which are happily in the .app bundle and working. When compiled under XCode 15, the application crashes because one of our .frameworks now tries to load these dylibs which cannot be found if run on a machine that didn't build it. Note that previously, this framework never depended on these dylibs before, but the application does. The rpaths for these dylibs are pointing to the build dependencies folder, which would only exist on a build machine. Also, the dependencies are now looking for versioned dylib filenames, while the application itself depends on the un-versioned dylib filenames. So to recap, that's 3 new problems when building with the new linker: The framework is now dependent on dylibs that normally only the application depends on The new dependency is on versioned dylibs, where the original application dependency is on un-versioned dylibs The framework's rpaths now include intermediate build folders Running otool -L on the framework binary shows a clear difference between ld_prime and ld_classic. The dependencies on the third-party dylibs are only showing up when the framework is built with the new linker. We have a couple of workarounds: Using ld_classic to build our application with the old linker Using post-build commands (install_name_tool) to change the dependencies and remove the build folders from the rpaths Though ultimately, workaround 1) could only be temporary and 2) is hacky. We'd like to understand why the linker is exhibiting this new behaviour, so we can make the proper adjustments to fix this the correct way. Any insight would be greatly appreciated. Thanks in advance. Note: this is a cross-platform product, and CMake is used to generate the .xcodeproj project file.

Second attempt to publish the Mac version of my App, but it was rejected again due to the same error: 'Library missing'. The library IS included with the build. The extracted .app from .xcarchive runs without a problem on different machines, both M1 and Intel. So, I don't know what's wrong. Can somebody please help me? I can provide the complete .ips from Apple if needed. { "code": 1, "flags": 518, "namespace": "DYLD", "indicator": "Library missing", "details": [ "(terminated at launch; ignore backtrace)" ], "reasons": [ "Library not loaded: @rpath/TitaniumKit.framework/Versions/A/TitaniumKit", "Referenced from: <85BA8613-0157-3B28-99AF-E73F1E579B72> /Applications/TiDesigner.app/Contents/MacOS/TiDesigner", "Reason: tried: '/usr/lib/swift/TitaniumKit.framework/Versions/A/TitaniumKit' (no such file, not in dyld cache), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/swift/TitaniumKit.framework/Versions/A/TitaniumKit' (no such file), '/usr/lib/swift/TitaniumKit.framework/Versions/A/TitaniumKit' (no such file, not in dyld cache), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/swift/TitaniumKit.framework/Versions/A/TitaniumKit' (no such file), '/System/Library/Frameworks/TitaniumKit.framework/Versions/A/TitaniumKit' (no such file, not in dyld cache), (security policy does not allow @ path expansion)" ] }

After reading An Apple Library Primer and watching Meet mergeable libraries (both really good resources) I'm sold on mergeable libraries. In my company we're working with static libraries as much as possible (both for precompiled dependencies and for our own Xcode projects). I can see that switching to mergeable libraries would (at least) improve iteration time because mergeable libraries would only be merged in release configs by default. You made it sound like it's "the holy grail of libraries". However, before starting the migration process I'd like to know: Is there any drawback to (merged) mergeable libraries when compared to using static libraries? I got the idea that mergeable libraries behave "almost" like static libraries after being linked "statically" with the app. What differences can I expect? Is there any situation where it's better to use static libraries instead of mergeable libraries? Thank you!

Hello there, I'm struggling with the following issue since Xcode 15 arrived and haven't been able to solve it. I have a go library c-archive library which I'm using in a iOS app and build were OK until Sonoma updated came last year. I updated all my go libraries and go runtime to latest version and still facing issues: my make script as follows: ios-arm64: CGO_ENABLED=1 GOOS=ios GOARCH=arm64 SDK=iphoneos SDK_PATH=xcrun --sdk iphoneos --show-sdk-path CARCH="arm64" CC=$(PWD)/clangwrap.sh CGO_CFLAGS="-fembed-bitcode" go build -v -buildmode=c-archive -ldflags="-s -w" -gcflags=all="-l -B" -tags ios -o $(IOS_OUT)/btfs.a . If there is anything else you need I can share more details. Thanks!

Are mergeable libraries compatible with digital signatures and privacy manifests? If so, what happens to the privacy manifests from each merged library? Do they get merged?

In Xcode 15 beta 6, building any Mac Catalyst project will encounter the following Linker warning. ld: warning: building for 'macCatalyst', but linking in dylib (/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa.tbd) built for 'macOS'

I am new to Xcode and trying to learn and having issues with errors it seems. I believe the problem is specifically with my code not being able to be displayed on the example iPhone on the right hand side of the screen. Here are the 2 errors I receive below. The codes at the very bottom are red on my screen so I am guessing those are what is most important out of all of this. Thanks and please let me know if I can answer any additional questions regarding this.

Hello, I am developing a tool in python or nodejs to intercept flows between two applications (MITM). I want to use the FRIDA library, but when I use it I get the following error: Error: module not found at "/usr/lib/libSystem.B.dylib". Indeed, the library is not present in the folder. I tried to get help directly from FRIDA but I couldn't find any help and on the current forum I did see some posts talking about this problem but I couldn't solve it. Do you have an idea of how to solve this problem. Thank you. Ps: I'm new to the APPLE ecosystem (Mac mini - Apple M1)
