xcov is a friendly visualizer for Xcode's code coverage files.


sudo gem install xcov


  • Built on top of Fastlane, you can easily plug it on to your CI environment.
  • Blacklisting of those files which coverage you want to ignore.
  • Minimum acceptable coverage percentage.
  • Nice HTML reports.


  • Slack integration.



In order to make xcov run you must:

  • Use Xcode 7.
  • Have the latest version of Xcode command line tools.
  • Set your project scheme as shared.
  • Enable the Gather coverage data setting available on your scheme settings window.



xcov analyzes the .xccoverage files created after running your tests therefore, before executing xcov, you need to run your tests with either Xcode, xcodebuild or scan. Once completed, obtain your coverage report by providing a few parameters:

xcov -w LystSDK.xcworkspace -s LystSDK -o xcov_output

Parameters allowed

  • --workspace -w: Path of your xcworkspace file.
  • --project -p: Path of your xcodeproj file (optional).
  • --scheme -s: Scheme of the project to analyze.
  • --output_directory -o: Path for the output folder where the report files will be saved.
  • --derived_data_path -j: Path of your project Derived Data folder (optional).
  • --minimum_coverage_percentage -m: Raise exception if overall coverage percentage is under this value (ie. 75).
  • --include_test_targets: Enables coverage reports for .xctest targets.
  • --ignore_file_path -x: Relative or absolute path to the file containing the list of ignored files.
  • --exclude_targets: Comma separated list of targets to exclude from coverage report.
  • --slack_url -i: Incoming WebHook for your Slack group to post results (optional).
  • --slack_channel -e: Slack channel where the results will be posted (optional).
  • --skip_slack: Add this flag to avoid publishing results on Slack (optional).

Ignoring files

You can easily ignore the coverage for a specified set of files by adding their filenames to the ignore file specified with the --ignore_file_path parameter (this file is .xcovignore by default). You can also specify a wildcard expression for matching a group of files.

Each one of the filenames you would like to ignore must be prefixed by the dash symbol -. In addition you can comment lines by prefixing them by #. Example:

# Api files
- LSTSessionApi.swift
- LSTComponentsApi.swift
- LSTNotificationsApi.swift

# Managers
- LSTRequestManager.m
- LSTCookiesManager.m

# Utils
- LSTStateMachine.swift

# Exclude all files ending by "View.swift"
- .*View.swift


Fastlane 1.61.0 includes xcov as a custom action. You can easily create your coverage reports as follows:

  workspace: "YourWorkspace.xcworkspace",
  scheme: "YourScheme",
  output_directory: "xcov_output"



  • Ignore file allows wildcards for matching a group of files (by stevenreinisch)
  • New exclude_targets option to exclude reporting for the targets given (by stevenreinisch)


  • Ignored coverage for a specified list of files


  • Fixed bug using the derived_data_path option
  • Fixed bug sorting multiple .xccoverage files by datetime


  • Additional flag to enable coverage reports for .xctest targets


  • Raised exception when the minimum coverage threshold is not reached (by opfeffer)


  • Fixed bug expanding/collapsing rows with same filename
  • Added Fastlane integration to README
