Sandbox error when compiling iOS with Hermes: "Operation not permitted" and "No such file or directory" (Apple Silicon/Xcode)

[FredAzevedo]

Bug Description

I'm experiencing sandbox errors when building a React Native project with Hermes enabled on iOS. The build fails with messages related to the Hermes framework, such as:

Sandbox: rsync(...) deny(1) file-read-data .../hermes.framework/Info.plist
Sandbox: rsync(...) deny(1) file-write-create .../hermes.framework/.hermes.XXXX
hermes.framework/hermes: utimensat (2): No such file or directory
Operation not permitted

Environment:

1. macOS: [Sonoma 14.2]
2. Xcode: [15.3]
3. React Native: 0.81.4
4. Hermes: default (bundled with React Native)
5. Apple Silicon: [M1]

What I have tried:

1. Gave Full Disk Access to Xcode in System Preferences.
2. Cleaned Xcode cache (rm -rf ~/Library/Developer/Xcode/DerivedData).
3. Ran pod deintegrate and pod install in the ios folder.
4. Updated all dependencies with yarn upgrade and pod update.
5. Built the project directly in Xcode.
6. Tried running Xcode under Rosetta.
7. Checked folder permissions with chown.

Detailed log:

Sandbox: rsync(7116) deny(1) file-read-data /Users/fredazevedo/Library/Developer/Xcode/DerivedData/associanet-fnbakryxbfssxlbjmkzzrxdalzcl/Build/Products/Debug-iphonesimulator/XCFrameworkIntermediates/hermes-engine/Pre-built/hermes.framework/Info.plist
Sandbox: rsync(7117) deny(1) file-write-create /Users/fredazevedo/Library/Developer/Xcode/DerivedData/associanet-fnbakryxbfssxlbjmkzzrxdalzcl/Build/Products/Debug-iphonesimulator/associanet.app/Frameworks/hermes.framework/.hermes.h0TkeTJQAi
hermes.framework/hermes: utimensat (2): No such file or directory
Operation not permitted

Question:

How can I resolve this sandbox error? Is there any extra configuration for Hermes or a workaround for Apple Silicon/Xcode builds?

Hi, unfortunately this (the packaging and how it is consumed by Xcode) is not something that the Hermes team maintains and we can't help. I will ask around.
