Fix: Sentry-CLI Build Upload Failure on Xcode Cloud with .xarchive Path

Hey everyone! 👋 Ever faced the frustrating issue of Sentry-CLI build uploads failing on Xcode Cloud when dealing with a .xarchive path? You're not alone! This article dives deep into a common problem encountered when integrating Sentry with Xcode Cloud and provides a comprehensive guide to troubleshoot and resolve it. Let's get started and ensure those builds upload smoothly!

Understanding the Issue

The core problem lies in how Sentry-CLI interprets the .xarchive format. When you run the command sentry-cli build upload $CI_ARCHIVE_PATH --build-configuration Release within your Xcode Cloud ci_post_xcodebuild.sh script, you might encounter the following error:

error: File is not a recognized supported build format (APK, or AAB): /Volumes/workspace/build.xcarchive

This error message indicates that Sentry-CLI doesn't recognize .xarchive as a valid build format for direct upload. It primarily supports formats like APK (Android Package) and AAB (Android App Bundle). The .xarchive file, while containing all the necessary information to build your iOS app, isn't in a format that Sentry-CLI can directly process for symbolication and other build-related tasks. Let's explore the reasons behind this and how to tackle it effectively.

When diving into this issue, it's crucial to understand why the .xarchive format isn't directly supported by Sentry-CLI for build uploads. The main reason is that .xarchive is an archive format specific to Xcode, primarily used for storing build artifacts. This format contains the compiled application, along with debugging symbols (dSYMs), and other metadata necessary for tasks like archiving and distribution. However, Sentry-CLI, designed to handle various platforms, expects specific build formats like APK for Android or AAB, which are structured differently. This discrepancy in expected formats leads to the "File is not a recognized supported build format" error.

Furthermore, the process of extracting relevant debugging symbols and other information from a .xarchive file requires specific tooling and handling that Sentry-CLI might not natively incorporate for all archive formats. Instead, Sentry recommends uploading the dSYMs (Debug Symbols) directly, which are crucial for symbolication—the process of converting memory addresses in crash reports back to human-readable function names and file locations. This allows Sentry to accurately pinpoint the source of errors in your iOS application. The next sections will delve into the exact steps you need to take to correctly upload dSYMs and other necessary files to Sentry, ensuring your crash reports are fully symbolicated and actionable.

Prerequisites and Environment

Before diving into the solution, let's ensure we have a clear understanding of the environment and the tools we're working with:

  • Sentry Account and Project: You should have a Sentry account and a project set up for your iOS application. This is where your crash reports and other data will be stored.
  • Sentry-CLI: Make sure you have Sentry-CLI installed and configured correctly. This command-line tool is essential for interacting with the Sentry API, including uploading dSYMs and source maps.
  • Xcode Cloud: We're working within the context of Xcode Cloud, so familiarity with its CI/CD pipeline is beneficial. Key environment variables like $CI_ARCHIVE_PATH (which points to the .xarchive file) are provided by Xcode Cloud.
  • CI_POST_XCODEBUILD.sh Script: This script is where we'll implement the fix. It's executed after the Xcode build process, making it an ideal place to upload build artifacts to Sentry.

Solution: Uploading dSYMs and Source Maps

The key to resolving this issue is to upload the dSYMs (Debug Symbols) and source maps directly to Sentry, rather than attempting to upload the entire .xarchive file. Here's a step-by-step guide:

1. Locate dSYMs

The dSYMs are located within the .xarchive file. To access them, you'll need to navigate inside the archive. You can do this using the cd command in your terminal:

cd "$CI_ARCHIVE_PATH/dSYMs"

This command changes the directory to the dSYMs folder within your archive. Here, you'll find the dSYMs files, which are essential for symbolication.

2. Upload dSYMs to Sentry

Now that you're in the dSYMs directory, you can use Sentry-CLI to upload these files. The command to use is:

sentry-cli debug-files upload --project your-sentry-project-name .

Important: Replace your-sentry-project-name with your actual Sentry project name. The . at the end of the command specifies the current directory as the source for dSYMs.

3. Upload Source Maps (if applicable)

If your project uses source maps (e.g., for JavaScript or React Native code), you should upload them as well. Source maps help Sentry map minified code back to its original source, making it easier to debug errors. The command to upload source maps might look something like this:

sentry-cli sourcemaps upload --project your-sentry-project-name your-source-maps-directory

Replace your-sentry-project-name with your Sentry project name and your-source-maps-directory with the path to your source maps.

4. Adjust your ci_post_xcodebuild.sh Script

Integrate these steps into your ci_post_xcodebuild.sh script. Your script might look something like this:

#!/bin/bash

# Navigate to the dSYMs directory
cd "$CI_ARCHIVE_PATH/dSYMs"

# Upload dSYMs to Sentry
sentry-cli debug-files upload --project your-sentry-project-name .

# Navigate back to the workspace root
cd $CI_WORKSPACE

# Upload source maps (if applicable)
if [ -d "your-source-maps-directory" ]; then
  sentry-cli sourcemaps upload --project your-sentry-project-name your-source-maps-directory
fi

echo "dSYMs and source maps uploaded to Sentry successfully!" #Guys, remember to replace “your-sentry-project-name” with your actual Sentry project name and
