I'd love to know as well. I still can't believe there are no proper way for Xcode to use the system settings or a custom settings through preferences.... The workaround that consist to change the java exec doesn't work anymore as it's been removed in Xcode 14. Set the JAVA_TOOL_OPTION variable neither... You know there are, unfortunately, loads of people that have to work behind a company proxy ?

@eskimo, can you link the issue 36287120 please ? I can't find it. I already tried using SwiftPM from the command line, but it doesn't solve the problem. For example, even though I run successfully xcodebuild -resolvePackageDependencies -scmProvider system from the command line, it's not picked up by xcode. Therefore Xcode isn't able to compile my app... When looking into the derived data, the command line produces a different folder than Xcode, which explains why it's not linked to Xcode. Am I missing something ? I don't find anything in xcodebuild's documentation that would mention anything else about resolvePackageDependencies.

I’m getting the same error as well with Xcode 16 and Swift 6, with also other files showing the same error : MyApp.abi.json MyApp.swiftdoc MyApp.swiftmodule MyApp.swiftsourceinfo Cleaning the project, removing the derived data, deleting every external dependencies and re-fetching them didn’t change anything.

@DTS Engineer Well, the files are missing … how can it be missing if the compilation went well? I’d expect the compiler to fail before. I tried compiling directly with xcodebuild to see if I can see something not showing up in xcode, but no luck.

Sorry for the misunderstanding, my bad. When I wrote the post, the files were here. Then I tried again cleaning everything, compiled again, then the files were missing. I forgot to specify that in my previous comment ^^ I realized that sometimes the error message changes slightly. Instead of showing these four files, it’d only show some of them. For example, I just modified the file Router.swift. Compiled again and the error message became : File cannot be open()ed, errno=2 path=/Users/MyUser/Library/Developer/Xcode/DerivedData/MyApp-euxwyncffackymerzuntbjccezyq/Build/Intermediates.noindex/MyApp.build/Debug-iphonesimulator/MyApp.build/Objects-normal/x86_64/Router.o in '/Users/MyUser/Library/Developer/Xcode/DerivedData/MyApp-euxwyncffackymerzuntbjccezyq/Build/Intermediates.noindex/MyApp.build/Debug-iphonesimulator/MyApp.build/Objects-normal/x86_64/Router.o' Yes I ran the test and it compiled properly.

Can you tell me which version of Tuist you’re using ? I’ll reach out to the Tuist team.

@oiuhr I had a chat with the Tuist team. It doesn’t seem to be related to Tuist, but let us know if you find anything. I’ll keep looking as well :) Thanks!
