Xccov::Parse

Add this line to your application's Gemfile:

gem 'xccov-parse'

And then execute:

$ bundle

Or install it yourself as:

$ gem install xccov-parse

1. Generate the json result by xcrun xccov view --only-targets --json

   # target: https://github.com/KazuCocoa/test.examples
   $ git clone https://github.com/KazuCocoa/test.examples && cd test.examples
   $ xcodebuild -workspace test.examples.xcworkspace -scheme test.examples -derivedDataPath Build/ -destination 'platform=iOS Simulator,OS=11.3,name=iPhone 7' -enableCodeCoverage YES clean build test CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO

2. Read the JSON and get a particular line coverage

   xccov = Xccov.new
   xccov.help
   json = xccov.view '--only-targets', '--json', 'Build/Logs/Test/*.xccovreport'
   parsed = Xccov::Parse.new(json: json)
   parsed.targets_line_coverage["test.examples.app"] #=> 0.35
   
   # or
   # $ xcrun xccov view --only-targets --json Build/Logs/Test/*.xccovreport > result.json
   parsed = Xccov::Parse.new(file: './result.json')
   parsed.targets_line_coverage["test.examples.app"] #=> 0.35
