Uploading dSYM files on iOS

Information about crashes on iOS is sent in unsymbolicated crash logs. It's difficult to extract data for analysis from these crash logs. To analyze the crash logs, upload dSYM files to AppMetrica.

The AppMetrica SDK has a built-in command-line tool named helper for uploading dSYM files. To build an app based on fastlane, use the upload plugin. It helps you set up automatic dSYM file uploads when building your app.

Automatic uploading when building an app

Use fastlane to build your app:

  1. Install the appmetrica fastlane plugin:

    fastlane add_plugin appmetrica

    For more information about how to add the plugin, see fastlane docs.

  2. Add the following to the fastlane/Fastfile file:

    lane :release do
# Your actions before.
gym(
workspace: "MyApp.xcworkspace",
configuration: "Release",
scheme: "MyApp",
export_method: "app-store"        # Pass the correct export_method.
)
upload_symbols_to_appmetrica(post_api_key: "Post API key")
# Your actions after.
end

    You can get the Post API key in the AppMetrica Settings. It's used to identify your app.

    Alert

    Apps are built using the gym action with export enabled. If you build your app using Xcode, the app is recompiled after you upload it to App Store Connect. In this case, you won't be able to use the dSYM files generated during the build.

  3. Add a stage for uploading dSYM files via the helper. The helper tool has been supported since version 3.8.0 of the AppMetrica SDK. It's in the SDK archive. Helper tool reference.

    1. Open the project in Xcode.

    2. In the project navigator, select the project file.

    3. In the Targets block, select your app.

    4. Open the Build Phases tab.

    5. Click + → New Run Script Phase.

    6. Add the following to the Type a script field:

      if [ -d "${PODS_ROOT}/AppMetricaCrashes" ]; then
HELPER_PATH=`find "${PODS_ROOT}/AppMetricaCrashes" -name "helper"`
if [ -x  "${HELPER_PATH}" ]; then
"${HELPER_PATH}" auto --post-api-key="Post API key"&
else
echo "AppMetrica crash helper was not found"
fi
fi

      Note

      auto mode uses the CONFIGURATION environment variable. If the build is done with the Debug configuration, no dSYM files are uploaded.

Uploading a missing dSYM file

If a dSYM file wasn't uploaded when building an app, crash reports contain a warning about unsymbolicated crashes.

To symbolicate them, upload the missing dSYM files. You can view the list of missing files on the Settings → Crashes page of your app in AppMetrica.

You can upload missing dSYM files:

  1. Install the appmetrica fastlane plugin:

    fastlane add_plugin appmetrica

    For more information about how to add the plugin, see fastlane docs.

  2. Add the following to the fastlane/Fastfile file:

    lane :refresh_dsyms do
download_dsyms
upload_symbols_to_appmetrica(post_api_key: "Post API key")
clean_build_artifacts
end

    In the download_dsyms action, you can specify the required app version and build number:

    ...
download_dsyms(version: "1.0.0", build_number: "345")
...

    Learn more about the download_dsyms action in the fastlane documentation.

  1. Find the necessary archive with the dSYM file:

    Via Xcode Organizer
    1. In the Xcode interface, click Window → Organizer.
    2. In the Archives tab, select the appropriate app version.
    3. Click Download dSYM.
    Via App Store Connect
    1. In the iTunes Connect interface, open the Activity page.
    2. In the All Builds tab, select the appropriate build number.
    3. Click Download dSYM.

    You can use the dSYM file that was generated during the build.

  2. In the AppMetrica interface, go to the app settings from the menu on the left.

  3. Open Crashes → iOS.

  4. Click Choose file and upload the ZIP archive containing the app.dSYM or app directory.

Alert

This option is only suitable for apps that are built without Bitcode.

To use the plugin, install the AppMetrica SDK with version 3.8.0 or higher. To upload missing dSYM files to AppMetrica, run the following command in the terminal:

helper -k <post-api-key> <file_path>

file_path — A list of dSYM files or the folders where they're stored.

Helper tool reference.

Helper tool reference

Note

The helper tool has been supported since version 3.8.0 of the AppMetrica SDK. It's in the SDK archive.

Helper is a command-line tool that lets you upload dSYM files to AppMetrica.

$ helper [auto] [-o | --package-output-path=<path>] [-v | --verbose]
         [--version] -k <post-api-key> | --post-api-key=<key> [file ...]

Parameters

auto

Auto upload mode. In this mode, the helper uses the following variables:

  • CONFIGURATION — Used to define the configuration. If the build is done with the Debug configuration, no dSYM files are uploaded.
  • DWARF_DSYM_FOLDER_PATH — Used to find dSYM files. It usually depends on the BUILT_PRODUCTS_DIR variable.
  • AMA_POST_API_KEY — Post API key. If specified, you can use the short helper auto& command in the auto mode.

‑k

Post API key. You can get the Post API key in the Settings of AppMetrica. It's used to identify your app.

‑o

The path to the folder where temporary files are stored.

By default, the system folder is used.

‑v

Enables the display of additional information.

‑‑version

Outputs the version.

file

The list of dSYM files or folders where they're stored.

By default, the local working folder is used.

& lets you run the helper concurrently, without blocking the build of the entire project. Sample command:

helper auto --post-api-key="Post API key"&
