CircleCI 2.0 for macOS General Availability

The release of CircleCI 2.0 for macOS enables your iOS projects to benefit from the significant performance, stability, and reliability improvements in the CircleCI 2.0 platform, including the following new features:

Workflows: Orchestrate jobs and steps with great flexibility using a simple set of new keys in your configuration. Increase the development speed through faster feedback, shorter reruns, and more efficient use of resources.

Advanced caching: Speed up builds by caching files from run to run using keys that are easy to control with granular caching options for cache save and restore points throughout your jobs. Cache any files from run to run using keys you can control.

Get started with the complete set of documentation for the macOS platform:

Docker Layer Caching in Machine Executor

Docker Layer Caching is now available as a premium feature for the machine executor. Refer to the Docker layer Caching in Machine Executor section for instructions.

Rerun Button Change on the Jobs Page

The button on the Jobs page has changed for jobs that run as part of a workflow. The rebuild options that are not compatible with Workflows have been removed from the button on the Jobs page. Jobs that ran as part of a workflow will only include the Rerun Job with SSH button on the Jobs page.

To rerun a job that ran as part of a workflow, you must navigate to the Workflows page of the CircleCI application and either rerun your entire Workflow or rerun your Workflow from failed jobs.

Scheduled Workflows

This feature enables Workflows to run on a configurable schedule. Refer to the Scheduling a Workflow section of the Orchestrating Workflows document for instructions and examples. Reference information for syntax is available in the triggers section of the Writing Jobs With Steps document and answers to common questions are documented in the Workflows section of the Migration FAQ.

Xcode 9 available on CircleCI for macOS

Today we updated our Xcode 9.0 image with the just released Xcode 9.0 GM Seed (build version 9A235). Please check out this post on our Discuss site for more details on how to use the latest Xcode in your macOS builds.

Minutes Used in Your Plan

This feature adds the used minutes to your Org Settings > Plan Settings page. This feature displays used minutes against Linux machines. It expands on our current functionality which shows minutes used against OS X machines and is located on the same page: Org Settings > Plan Settings.

Data appears for Orgs with a billing date after Aug 31, 2017. So, a new org will immediately see minutes used, and existing orgs will see the minutes used appear within the coming 30 days, depending on the billing date for your plan.

Workflows Graph

This feature enables an interactive graph of your workflow configuration. Refer to the instructions and examples in the Orchestrating Workflows document.

Xcode 9.0 Beta 5

Today we updated our Xcode 9.0 beta 3 image to Xcode 9.0 beta 5 (build version 9M202q) with the latest simulators.

You can use this image by specifying Xcode 9.0 in your circle.yml:

machine:
  xcode:
    version: "9.0"

This image tag will be automatically upgraded when new betas are released by Apple, until the final release of Xcode 9.

Contexts

This feature enables sharing of global environment variables across projects. Refer to the instructions and examples in the Setting Contexts document and the Job Contexts Example section of Orchestrating Workflows.

CircleCI 2.0 Git Tags Support

This feature enables filtering on Git tags for jobs in workflows using CircleCI 2.0. CircleCI will not run a job for a Git tag unless a tags filter is specified. Refer to the instructions and examples in the Workflow Tags section of Writing Jobs With Steps and in the Git Tag Job Execution section of Orchestrating Workflows.

CircleCI 2.0 General Availability

CircleCI 2.0 is a completely updated CI/CD platform that starts every run with a clean image which is automatically provisioned just-in-time for Linux and Android jobs on the hosted CircleCI application.

Configuration moves into the code in 2.0, so every developer can configure jobs directly in their working branch, teams can try new things without the risk of slowing anyone else down, and business leaders have the ability to operate large global teams with minimal overhead. CircleCI 2.0 prevents you from writing clean-up scripts because every run starts in the same state, eliminating the risk of polluting a test database or leaving files in places that cause problems for the next run.

The CircleCI 2.0 platform includes significant performance, stability, and reliability improvements along with the following new features:

  • First-class Docker Support: Choose any image to run your job steps, customizable on a per-job basis on a particular Git branch. Speed up your run times with advanced layer caching. Build docker images with full docker CLI support and full support for docker compose. Support for all programming languages and custom environments that offer more predictable output. See Specifying Container Images for instructions.

  • Workflows: Orchestrate jobs and steps with great flexibility using a simple set of new keys in your configuration. Share temporary files between jobs with workspaces for fan-in, fan-out, parallel, and sequential runs. Hold a workflow for a manual approval and restart a workflow from a failed job. See Orchestrating Workflows for details.

  • Resource Allocation: Configure your CPU and RAM needs on a per-job basis at the branch level, see the resource_class documentation for instructions. Paid accounts may request this feature from their Customer Success Manager, non-paid users may request to get started by sending email to support@circleci.com.

  • Insights: Access interactive charts and analyses in seconds. Visualize trends in your build history to identify and pinpoint bottlenecks. Understand all of your builds at a glance. View the builds that fail most, so you can fix the slowest tests to improve efficiency. See the Collecting Test Metadata documentation for information.

  • Debugging with SSH and CLI: Perform local job runs, configuration validation and SSH in to builds for access to log files and debugging running processes. See Using the CLI documentation to learn about running local jobs and refer to Debugging Jobs over SSH for SSH instructions.

  • Parallelism: Automatic provisioning of containers as they are freed without waiting for other jobs to finish. See the Parallel Job Execution documentation for examples.

  • Advanced Caching: Speed up builds by caching files from run to run using keys that are easy to control with granular caching options for cache save and restore points throughout your jobs. Cache any files from run to run using keys you can control, see the Caching Dependencies documentation for strategies and steps.

  • Demonstration Applications: See the Language Guides and Demo Repos to learn CircleCI configuration by example for applications written in Go, Javascript, PHP, Python (Django and Flask), Ruby on Rails, Java, Elixir, and Clojure.

  • New Documentation: New and restructured documentation including an Overview, Hello World, Sample 2.0 config.yml File, simplified instructions for Migrating from 1.0 to 2.0, plus examples for Configuring Databases and Creating Custom Docker Images. Refer to the Migration FAQ for common questions and known limitations.

Pricing Plan Change

A fix to the pricing plan has been implemented which limits Linux plan capacity to the published maximum. As a result of this change, you may see builds queuing until the requisite containers are available.

CircleCI 2.0 Core Dump Support

This feature enables core dumps for projects using CircleCI 2.0. Get core dump files and push them as artifacts for inspection and debugging using the instructions in the Uploading Build Artifacts document.

Xcode 9 Beta 2

Today we updated our Xcode 9.0 beta image to Xcode 9.0 beta 2 with the latest 10.2 simulators. To start using it, add the following to your circle.yml:

  xcode:
    version: "9.0"

This image tag will be upgraded automatically when new betas are released by Apple, until the final release of Xcode 9.

Xcode 8.3.3

For mobile, we have just released a build image that allows you to use the latest stable version of Xcode, 8.3.3. To start using it, add the following to your circle.yml:

  xcode:
    version: "8.3.3"

Workflows

The Workflows feature is available on CircleCI 2.0. It is designed with a flexible algorithm to support very complex job scheduling and orchestration using a simple set of new configuration keys. See the Steps to Configure Workflows section of the Migrating from 1.0 to 2.0 document for instructions. Refer to the Orchestrating Workflows document for examples and conceptual information.

Xcode 9 Beta 1 Availability

This update makes Xcode 9 Beta available for all macOS builds. Specify version 9.0 in your circle.yml file to override the default.

Authenticate With Google

This feature enables users to log in to CircleCI with a Google account and provides new users with the opportunity to experience the application and selected demo projects without providing access to their code repository.

Filter Build Emails by Project

Now you can filter your build emails by project without doing subject matching. This feature adds the standard List-ID header with organisation.project.notifications.circleci.com to make it easy to filter build emails into per-repo or per-org folders.

Import Project Environment Variables

This feature enables you to import project environment variables from projects in the same organization to save time and typing. On the Settings screen for your project, click the Import Variable(s) button on the Environment Variables page and select from the list.

Authorize Only Public GitHub Repositories

This feature enables you to join CircleCI without providing access to your private GitHub repos. To limit access, select Public Repos Only from the Start with Github menu on the signup page.

My/All Build Filtering

Looking for the builds most relevant to your actions? You can now filter builds by “my builds” (builds you triggered) or “all builds” (builds triggered by other users on your team). The filter can be found near the top, right-hand corner of your dashboard. Currently, this feature is only available on the organization and project-level.

Automatic collection of Fastlane logs for macOS projects

The logs produced by the Fastlane tools are now being stored as build artifacts so that you can easily access them later.

Granular control over fork PR builds

It is now possible to control whether to run builds for pull requests coming from forks and whether to pass the secrets from the main project to the fork on such builds, via two separate settings. Check out the Advanced Settings tab for your project for more details.

Improved code signing flow for OS X builds

It is now possible to upload provisioning profiles under the ‘Permissions’ section of your OS X project settings. Once uploaded, we will automatically import the profiles during your OS X builds. Profiles are encrypted at rest on the CircleCI side.

This update removes the need to keep the provisioning profiles checked into your repository and simplifies the setup of code signing for new OS X projects.

CircleCI offers the ability to link directly to build output steps. We’ve now extended this feature into build email notifications. You should now see a clickable ‘Failing Command’ on (failed) build notification emails which will open the build page to the failed command in your build output.

Confirmation modal for stop building projects on CircleCI,

We have added a confirmation message to prevent users from accidentally stopping the builds on CircleCI.

Interactive ‘Build Timing’ graph

We have added functionality to click through the ‘Build Timing’ graph to access different sections of the build.

Anchor to a particular step within build output

Users can show share link to a particular step within their build output; Eg. https://circleci.com/gh/spotify/helios/5091#tests/containers/0/actions/4

Flash notifications for adding & deleting keys

We have added flash notification when users add or remove Apple Code Signing key, API permissions, SSH key or environment variables.

Fetch CocoaPods from S3 instead of Git in iOS projects

A few weeks ago we started downloading CocoaPods specs from S3 instead of Git in projects that use our iOS inference. It is now also possible to download the specs from S3 in projects with manual configuration.

Please check out this Discuss post for an example of downloading specs from S3 via a circle.yml command.
