CodeSign error en macOS 26.2 / Xcode 26.2 con JUCE

Audio Plugins
1

Hi, I’m new to JUCE and following a tutorial to create an audio plugin. When I try to build the Standalone project in Xcode I get this error:

CodeSign /Users/fall/Desktop/Algebra_Delay_01/Builds/MacOSX/build/Debug/Algebra_Delay_01.app (in target ‘Algebra_Delay_01 - Standalone Plugin’ from project ‘Algebra_Delay_01’)
cd /Users/fall/Desktop/Algebra_Delay_01/Builds/MacOSX

Signing Identity:     "Sign to Run Locally"

/usr/bin/codesign --force --sign - --timestamp --entitlements /Users/fall/Library/Developer/Xcode/DerivedData/Algebra_Delay_01-cjnqsksvqtsiwecfayqsifkrvqoy/Build/Intermediates.noindex/Algebra_Delay_01.build/Debug/Algebra_Delay_01\ -\ Standalone\ Plugin.build/Algebra_Delay_01.app.xcent --generate-entitlement-der /Users/fall/Desktop/Algebra_Delay_01/Builds/MacOSX/build/Debug/Algebra_Delay_01.app

/Users/fall/Desktop/Algebra_Delay_01/Builds/MacOSX/build/Debug/Algebra_Delay_01.app: resource fork, Finder information, or similar detritus not allowed
Command CodeSign failed with a nonzero exit code

My setup: macOS 26.2 (Build 25C56), Xcode 26.2 (Build 17C52), Fresh project created from Projucer

What I’ve tried:

Cleaning metadata with xattr -cr , Deleting build folder, Setting Code-Signing Identity to empty or dash “-”, Both automatically and manually manage signing, Clean Build Folder. Anyone know how to fix this?

This Apple technical Q&A (Technical Q&A QA1940: Code signing fails with error 'resource fork, Finder information, or similar detritus not allowed') certainly seems to suggest the issue is due to extended attributes. Have you tried running the suggested command to find the offending files? Keep in mind fixing up the app bundle may not be enough you’ll have to consider how that file got into the bundle. Maybe you can try and remove all extended attributes throughout the entire project? I think that’s what this StackOverflow answer suggests https://stackoverflow.com/a/39667628
