Xcode version 15.0 - Command PhaseScriptExecution failed with a nonzero exit code

I just fixed the same issue!

I was installing Xcode 15 on my new machine M2 ( Apple Silicon ) so first of all, this is the general error message but you would need more details to understand the root cause of the issue.

Use the Xcode report navigator 🧐

To show the report navigator, either (1) click the rightmost button in the navigator bar at the top of the navigator area, which is on the left side of the workspace window, (2) select View > Navigators > Reports from the menu bar at the top of the screen, or press ⌘9.

After showing the report, I was able to identify the root cause which is Bad CPU type in executable as shown below:

So as I am using the M2 machine, I found the reason because when macOS tries to run an app that is not built for Apple silicon, macOS will prompt to install Rosetta 2 ( It enables a Mac with Apple silicon to use an app built for a Mac with an Intel processor. ) to automatically translate the app to Apple silicon but this did not automatically happen with my machine and maybe yours and also in Terminal, there is no automatic detection for missing Rosetta to run older architecture command line tools.

If you haven't been prompted for any other app already, manually install Rosetta 2:

softwareupdate --install-rosetta

Installing Rosetta 2:

Getting back to my Xcode and I was finally able to build the project successfully! It is simply because Xcode is one of the apps/tools that were originally designed for Intel-based Macs and are now translated by Rosetta 2 on Apple silicon Macs.

Good luck 🤞

After updating Xcode to 15.0 I am facing this issue. I have found a workaround for this issue. Please try the following steps:

1. Search for source="$(readlink "${source}")" in your project. I found it in Pods-[your-project-name]-frameworks.sh

2. Change source="$(readlink "${source}")" to source="$(readlink -f "${source}")"

I came across the same error & the solutions I found did not work. However on other projects the builds did actually worked but not on my new project. So i compared both projects and changed 2 elements and it works now!

1: .xcode.env.local

Location: app/ios/.xcode.env.local

I changed this

export NODE_BINARY="/opt/homebrew/Cellar/node/20.8.1/bin/node"

into this

export NODE_BINARY="/usr/local/bin/node"

2. Build Settings

update the Xcode project build option 'ENABLE_USER_SCRIPT_SANDBOXING' to 'No'.

After doing this, the application could be built!

I came across the same error too, here's how to actually debug the issue

• Identify the failing script phase, which in my case is the "Bundle React Native code and images."
• Expand the error log to view detailed steps. (click on hamburger menu to the right of script phase)

• Scroll down to locate the specific error message.

in my case it was this Error: Unable to resolve module ../../../../assets/icons/BullseyeIcon

• Fix any missing assets or incorrect paths in your code attempt to Archive the project again

Goodluck!

If you are developing the FLUTTER app, then try the below commands

     flutter clean
     flutter pub get

     cd ios
     pod install
     flutter build ios

once ios build is successfully done, then proceed with release steps in Xcode.

Upgrading to Unity version 2022.3.16f1 fixed it for me.

Here is my resolve (downgrade Xcode): Uninstall Xcode 15, then go to system settings of store, turn off auto update, then download old version of Xcode: https://developer.apple.com/download/all/ choose your old version which work for your work. Double click download file (.xip) to install then drag it to Apllication folder.

After updating Xcode to 15.0 I am facing this issue. I have found a workaround for this issue. Please try following step - it works for me with Xcode ver 15.2.

Change source="$(readlink -f "${source}")" to source="$(readlink "${source}")"

For React Native .74 - MAC M3

npx react-native-clean-project
cd ios && pod deintegrate
npx pod-install
npx react-native start --reset-cache

I am using Xcode v15.4 and react-native v0.73.6, and I got the same error when I tried to run it on my real device, It was working fine in the simulator. By following the steps below it fixed for me. You can try this fix if you are using any xcode v15.x

Xcode: 15.4

react-native: 0.73.6

macOS: 14.5 (23F79) M1 Chip

Steps:

1. From your react-native project navigator go to ios folder
2. Select [Your app name].xcodeproj folder
3. Select project.pbxproj
4. Search for arm64
5. You will get it at 3 places
6. Remove all 3 lines with arm64
7. Clean and build the project again

Hope this will fix your issue and save your day!

For me(running Xcode 15.0.1, not using RN or other libraries), the only way I finally got it working is Removing Pods/*, podfile.lock and rerunning pod install. All the others like setting -e to +e, editing in readlink did nothing to me.

The error doesn't provide much of a context, so I usually change the build destination to "Any iOS Simulator Device (x86_64)" as it might provide more context.

One possible cause is that you might have redeclared a function. Doing so results in the same error. The fix is to rename the function so that it has a distinct name.

Use the search bar to find:

source="$(readlink "${source}")"

And add -f flag to this line. Like this:

source="$(readlink -f "${source}")"

This must be a joke, because I used a space in the parent folder name and it got fixed when I remove

../React Native/project -> ../ReactNative/project
