That way, if something goes wrong or doesn’t work, you can always revert to the previous lockfile and go back to using Bundler 1. We recommend committing your Gemfile.lock before you upgrade. If your application is ready, you can upgrade that application to the latest installed version of Bundler by running bundle update -bundler. Bundler will never change your application to a new major version until you choose to do so. Your existing applications will continue to use Bundler 1. Upgrading applications from Bundler 1 to Bundler 2 Here’s an example Gemfile.lock that was created with Bundler 1.17.1. If your lockfile was created by Bundler 2, your commands will be run by Bundler 2. If your lockfile was created by Bundler 1, your commands will be run by Bundler 1. Now that you have Bundler 2 installed, you should know that Bundler will automatically switch between version 1 and version 2 based on your application’s Gemfile.lock. To install it the usual way, run gem install bundler and RubyGems will install the latest version of Bundler. The first step in upgrading to Bundler 2 is installing the Bundler 2 gem. If you need to upgrade RubyGems, run gem update -system.Īll set? Ruby and RubyGems versions new enough? Great. If you need to upgrade Ruby, use your ruby version manager’s instructions. You can check your Ruby version by running ruby -version, and you can check your RubyGems version by running gem -version. You need to be using Ruby 2.3.0 or higher, and you need to have RubyGems 2.5.0 or higher. Prerequisitesīefore you upgrade to Bundler 2, make sure you have the right Ruby and RubyGems. The big change is that Bundler now requires at least Ruby 2.3.0 and RubyGems 2.5.0. In order to try out the new Mac mini M2, contact our customer engineering team.So! You’ve heard that Bundler 2 was released! If you want to try out Bundler 2 for yourself, this guide will help you do that.īundler 2 is almost entirely the same as the previous version, 1.17. Reminder: Mac mini M1 build machines are already available on Codemagic as the default machine type. Most package managers and tools already support the new chips, so the transition is much easier than it was a year ago. Updating the tools and packages ensures that you are taking advantage of the raw power of Apple silicon instead of using Rosetta 2 emulation.Īpple silicon chips are the future of Mac hardware, and it only gets better from here on out. This gap accumulates when executing numerous builds, which you may do on a daily basis, ultimately saving a significant amount of time and providing a faster iteration process. We observe a reduction of 35–40% in overall build times when comparing the Mac mini M2 to Intel Mac Pro. You can see the significant differences in the numbers, especially while running tests - they execute much more quickly on the Apple Silicon build machines. As an open-source app, you are welcome to explore it yourself. This experiment presents you with a real-world scenario involving hundreds of tests. To appreciate the build time differences between the Apple Silicon and Intel machines and gain a clearer understanding of the enhanced efficiency and speed offered by the Mac mini M2 and Mac mini M1, we conducted tests on the official Wikipedia iOS app. Take a look at a few examples of such projects here. You can take inspiration from open-source projects that have been successfully migrated and work on the new chips. Build times for Mac mini M2, Mac mini M1 and Intel Mac Pro If you are switching from discrete framework bundles to XCFrameworks, follow the migration steps mentioned by Carthage here. You can check which shell program is running in your terminal with the following command: The default shell in macOS Big Sur and Monterey is zsh. This was announced back in January 2021, when /opt/homebrew became the default directory for Apple silicon instead of /usr/local on the Intel machines.Īt the time of writing this article (May 2023), most of the popular tools that use Homebrew already support the arm64 architecture, so it’s easier to update different software using Homebrew. The default path for Homebrew has changed for the new Apple Silicon machines, and you may need to update the path for Homebrew in your local machine and the path in your Codemagic workflow if you are using hard-coded paths. You may require versions of tools built specifically for arm64 architecture, e.g., Ruby. Homebrew is one of the recommended dependency managers. You can use it to install Ruby, dependency managers like CocoaPods and Carthage, or the popular automation tool fastlane. Homebrew is a popular package manager that helps you to simplify installing tools and software on your Mac machine.
