What is this?
This is a Swift/Xcode application, with basic unit tests, for which coverage is uploaded to Codecov on a daily basis. It can also serve as an example for how to integrate Codecov into your Swift/Xcode project. If the build is passing for this project, then Codecov's Swift/Xcode report processing is functional and correct on codecov.io.
This application is built in
Xcode 11 and uses
Swift 5. The UI for this application is built atop
SwiftUI. This project includes both unit and ui tests, written with the
XCTest framework. These tests are simulated on an
iPhone Xʀ running
iOS 13. Coverage reports are generated via Slather.
Slather configuration (.slather.yml):
Travis configuration (.travis.yml):
- gem install slather
- xcodebuild -scheme standard-swift -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone Xʀ,OS=13.0' build test
- bash <(curl -s https://codecov.io/bash) -f ./cobertura.xml
Processing Coverage Reports
By default, coverage reports are not generated for Xcode builds. To make sure your Xcode scheme generates coverage reports click on your scheme --> "Edit Scheme" --> "Test" --> check "Gather coverage." Now, coverage reports will automatically be generated for each build.
Xcode generates special
.xccoverage files which hold coverage information for each build. These files are not human readable and Codecov may run into errors while parsing these files. To get the relevant information out of these files after your build, it is recommended you use a tool like Slather to generate a
coverage.xml file that can then be uploaded to Codecov.
All Xcode projects include separate folders for unit tests and ui tests. In some instances, the files in these folders may arbitrarily inflate the overall coverage percentage reported by Codecov because they are automatically lumped together as a part of the coverage report. If you don't want to include these files, we recommend you use Slather as a part of your workflow to generate coverage reports as it will discard unit/ui test folders from your coverage report. Otherwise, you can choose to exclude these folders via your
.codecov.yml through ignore paths.
