Using CircleCI 2.0
We ‘ve been using CircleCI for many of our open source projects. Since the end of last year 2017, version 2.0 began to come out, and we think it’s good time to try it now together with Swift 4.1 and Xcode 9.3
The problem with version 2.0 is it’s so powerful and has lots of cool new features like jobs and workflows, but that requires going to documentation for how to migrate configuration file, especially Search and Replace Deprecated 2.0 Keys
The first thing is to create a new
config.yml inside folder
Copy your existing circle.yml file into a new directory called .circleci at the root of your project repository.
Next is to declare version and jobs
Add version: 2 to the top of the .circleci/config.yml file.
For simple cases, we just use
xcodebuild to build and test the project, so it’s good to try it locally to avoid lots of trial commits to trigger CircleCI. You can take a look at this PR https://github.com/hyperoslo/Cheers/pull/20
Before our configuration file for version 1.0 looks like this
- set -o pipefail && xcodebuild -project Cheers.xcodeproj -scheme "Cheers-iOS" -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 8,OS=11.0' -enableCodeCoverage YES test
Now we should put
shell, follow https://github.com/CircleCI-Public/circleci-demo-ios/blob/master/.circleci/config.yml
shell: /bin/bash –login -o pipefail
Now is the actual trying
xcodebuild, after many failures due to
xcodebuild: error: Unable to find a destination matching the provided destination specifier:
xcodebuild: error: option 'Destination' requires at least one parameter of the form 'key=value'
I found this to work, run this in the same folder as your
xcodebuild -project Cheers.xcodeproj -scheme "Cheers-iOS" -sdk iphonesimulator -destination "platform=iOS Simulator,OS=11.3,name=iPhone X" -enableCodeCoverage YES test
Version 2.0 introduces workflow which helps organising jobs
A workflow is a set of rules for defining a collection of jobs and their run order. Workflows support complex job orchestration using a simple set of configuration keys to help you resolve failures sooner.
For our simple use cases, we add this workflow
CircleCI collects test metadata from XML files and uses it to provide insights into your job
