Uploading Debug Symbols (iOS)

Learn more about how to upload debug symbols for iOS.

Sentry requires dSYMs (debug information files) to symbolicate your stack traces. The symbolication process unscrambles the stack traces to reveal the function, file names, and line numbers of the crash.

Every solution requires a Sentry Auth Token. You can create tokens on the Organization Auth Tokens settings page.

To view uploaded dSYMs in your project, select an existing project from the "Projects" page, then go to Settings > Debug Files. You can upload dSYMs using:

Starting with Xcode 13, newly generated projects don't automatically create a required Info.plist configuration file. If this is your situation, please read Info.plist Is Missing in Xcode 13 — Here's How To Get It Back.

Use the sentry-cli debug-files upload command to upload dSYMs to Sentry. The command will recursively scan the provided folders or ZIP archives. Files that have already been uploaded will be skipped automatically.

Sentry can display snippets of your code next to the event stack traces. This feature is called source context. When setting the --include-sources option, sentry-cli will scan your debug files to find references to the source code files, resolve them in the local file system, bundle them up, and upload them to Sentry.

For this to work, your project settings for DEBUG_INFORMATION_FORMAT must be set to DWARF with dSYM File, which is the default for release builds but not for debug builds.

You can also upload your code for source context. This feature allows Sentry to display snippets of your code next to the event stack traces.

Copied
sentry-cli debug-files upload --auth-token sntrys_YOUR_TOKEN_HERE \
  --include-sources \
  --org example-org \
  --project example-project \
  PATH_TO_DSYMS

You can find installation instructions for Sentry CLI https://docs.sentry.io/cli/installation/.

If you're already using Fastlane, you can use the Sentry Fastlane plugin to upload your dSYMs to Sentry.

Sentry can display snippets of your code next to event stack traces. This feature is called source context. When setting the include_sources parameter to true, the Fastlane plugin will scan your debug files to find references to the source code files, resolve them in the local file system, bundle them up, and upload them to Sentry.

Copied
sentry_debug_files_upload(
  auth_token: 'sntrys_YOUR_TOKEN_HERE',
  org_slug: 'example-org',
  project_slug: 'example-project',
  include_sources: true, # Optional. For source context.
)

Your project's dSYM can be uploaded during Xcode's build phase as a Run Script. To do this, set the DEBUG_INFORMATION_FORMAT to DWARF with a dSYM file. By default, an Xcode project will only have DEBUG_INFORMATION_FORMAT set to DWARF with a dSYM file in release, so make sure everything is properly set up in your build settings.

Follow these steps to upload the debug symbols:

  1. Download and install sentry-cli.
  2. Copy the script below into a new Run Script and set your AUTH_TOKEN, ORG_SLUG, and PROJECT_SLUG. Sentry can display snippets of your code next to the event stack traces. This feature is called source context. When setting the --include-sources option, sentry-cli will scan your debug files to find references to the source code files, resolve them in the local file system, bundle them up, and upload them to Sentry.

For this to work, your project settings for DEBUG_INFORMATION_FORMAT must be set to DWARF with dSYM File, which is the default for release builds but not for debug builds. If you don't want Sentry to upload your source code, remove the --include-sources argument from the copied script.

Copied
if [[ "$(uname -m)" == arm64 ]]; then
    export PATH="/opt/homebrew/bin:$PATH"
fi

if which sentry-cli >/dev/null; then
export SENTRY_ORG=example-org
export SENTRY_PROJECT=example-project
export SENTRY_AUTH_TOKEN=sntrys_YOUR_TOKEN_HERE
ERROR=$(sentry-cli debug-files upload \ 
--include-sources \
"$DWARF_DSYM_FOLDER_PATH" 2>&1 >/dev/null)
if [ ! $? -eq 0 ]; then
echo "warning: sentry-cli - $ERROR"
fi
else
echo "warning: sentry-cli not installed, download from https://github.com/getsentry/sentry-cli/releases"
fi

You can add --force-foreground argument to sentry-cli to help you debug any error that could happen during the upload process.

  1. You also need to add the following line to the Input Files section in the Run Script from step 2:
Copied
${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${TARGET_NAME}
  1. Set ENABLE_USER_SCRIPT_SANDBOXING in your Xcode project settings to NO.
