Hi! I have a bigger Xcode project that has multiple targets: the main app (MainApp) helper command line tool (HelperTool) The project also lists multiple package dependencies via SwiftPM and these dependencies have dependencies between themselves. One of such packages produces a dynamic library MyFramework which is a dependency for both the main app and the HelperTool which has it listed under Build Phases > Dependencies as well as under Link with Frameworks. This builds just fine, but the issue somes when I want to add another target called AdditionalHelperTool which it has pretty much the same dependencies as HelperTool. When I add this second target, I start running into issues like the following: Multiple commands produce '[...]/Build/Products/Debug/Frameworks/MyFramework.framework/Versions/A' Target 'HelperTool' (project 'MyApp') has copy command from '[...]/Build/Products/Debug/PackageFrameworks/MyFramework.framework' to '[...]/Build/Products/Debug/Frameworks/MyFramework.framework' Target 'AdditionalHelperTool' (project 'MyApp') has copy command from '[...]/Build/Products/Debug/PackageFrameworks/MyFramework.framework' to '[...]/Build/Products/Debug/Frameworks/MyFramework.framework'` It seems that Xcode runs the build of both targets separately and it sees a conflict given that both targets have same dependencies that it's trying to built separately. Has anyone encountered something similar? Can anyone suggest a solution for this?

Hi! I've been scratching my brain for a few days now to no avail. I have a Perl project that I need to embed within my app. Perl includes a pp command (https://metacpan.org/pod/pp) which takes the runtime binary and then slaps the Perl code at the end of the binary itself which in brings some woes in a sense that the binary then needs to be "fixed" (https://github.com/rschupp/PAR-Packer/tree/master/contrib/pp_osx_codesign_fix) by removing the linker-provided signature and fixing LINKEDIT and LC_SYMTAB header sections of the binary. Nevertheless, I've successfully gotten the binary built, fixed up and codesigned it via codesign -s '$CS' mytool (where $CS is the codesigning identity). I can verify the signature as valid using codesign -v --display mytool: Identifier=mytool Format=Mach-O thin (arm64) CodeDirectory v=20400 size=24396 flags=0x0(none) hashes=757+2 location=embedded Signature size=4820 Signed Time=5. 1. 2026 at 8:54:53 PM Info.plist=not bound TeamIdentifier=XXXXXXX Sealed Resources=none Internal requirements count=1 size=188 It runs without any issues in Terminal, which is great. As I need to incorporate this binary in my app which is sandboxed, given my experience with other binaries that I'm including in the app, I need to codesign the binary with entitlements com.apple.security.app-sandbox and com.apple.security.inherit. So, I run: codesign -s '$CS' --force --entitlements ./MyTool.entitlements --identifier com.charliemonroe.mytool mytool ... where the entitlements file contains only the two entitlements mentioned above. Now I add the binary to the Xcode project, add it to the copy resources phase and I can confirm that it's within the bundle and that it's codesigned: codesign -vvvv --display MyApp.app/Contents/Resources/mytool Identifier=com.xxx.xxx.xxx Format=Mach-O thin (arm64) CodeDirectory v=20500 size=24590 flags=0x10000(runtime) hashes=757+7 location=embedded VersionPlatform=1 VersionMin=1703936 VersionSDK=1704448 Hash type=sha256 size=32 CandidateCDHash sha256=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9e CandidateCDHashFull sha256=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9edf463ce45d1cd3f89a6a4a00 Hash choices=sha256 CMSDigest=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9edf463ce45d1cd3f89a6a4a00 CMSDigestType=2 Executable Segment base=0 Executable Segment limit=32768 Executable Segment flags=0x1 Page size=16384 CDHash=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9e Signature size=4800 Authority=Apple Development: XXXXXX (XXXXXX) Authority=Apple Worldwide Developer Relations Certification Authority Authority=Apple Root CA Signed Time=9. 1. 2026 at 5:12:22 PM Info.plist=not bound TeamIdentifier=XXXXX Runtime Version=26.2.0 Sealed Resources=none Internal requirements count=1 size=196 codesign --display --entitlements :- MyApp.app/Contents/Resources/mytool <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "https://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>com.apple.security.app-sandbox</key><true/><key>com.apple.security.inherit</key><true/></dict></plist> All seems to be in order!

So I ran: xattr -l MyApp.app/Contents/Resources/mytool None listed. It is a signed binary within a signed app. There are other binaries that are included within the app and run just fine exactly this way (most of them built externally using C/C++ and then codesigned exectly as per above), so I really don't think it's an issue with the app's sandbox setup... Is there anyone who would be able to help with this? Thank you in advance!
