This repository serves as an example on how to use Codecov Global for Xcode in both Objective-C and Swift.

• Create a shared scheme for your test target https://i.imgur.com/JKNFq0G.png
• At the highest, your deployment target can be 8.1 or earlier. This will update as Travis supports more simulators.
• Write unit tests
• Setup your CI

xctool also does not respect the /Scheme/TestAction/@codeCoverageEnabled setting in .xcscheme files. Make sure -enableCodeCoverage YES is set.

Add to your .travis.yml file.

language: objective-c
script: 
  - xctool -project {{path_to_xcodeproj}} -scheme {{your_testing_scheme}} build test -sdk iphonesimulator GCC_INSTRUMENT_PROGRAM_FLOW_ARCS=YES GCC_GENERATE_TEST_COVERAGE_FILES=YES
after_success:
  - bash <(curl -s https://codecov.io/bash)

Reference http://docs.travis-ci.com/user/languages/objective-c/

The two important parts are:

• GCC_INSTRUMENT_PROGRAM_FLOW_ARCS=YES GCC_GENERATE_TEST_COVERAGE_FILES=YES (To have Xcode create code coverage files)
• bash <(curl -s https://codecov.io/bash) (To upload code coverage to Codecov.io)

This is used to have Xcode output code coverage files for Codecov.io to process.

Set CODECOV_TOKEN in your environment variables.

Add to your .travis.yml file.

after_success:
  - bash <(curl -s https://codecov.io/bash) -t :uuid-repo-token

Or you can set the enviornment variable CODECOV_TOKEN to your token.
