Catalina

We have released Xcode 11.2, which will replace the beta release.

The new image contains Xcode 11.2, running on Catalina.

Hi, I am running Xcode 12.4 on Catalina 10.15.7. The app seems to be working well, quite smooth i must say. The problem i'm facing is that when i downloaded and installed additional simulators for iOS versions below 14 (which is the officially supported version in Xcode 12.4) e.g. Gyp: No Xcode or CLT version detected! Reference: Installation notes for macOS Catalina (v10.15) Check MacOS version. Run swvers in terminal to check your MacOS version. I would like to say no. I have a habit of taking the backup of old macOS and x code I am using Xcode 9.4 and 10.3 which I am using ow also. But I start to use Xcode 11.1 is the latest Xcode version for Mojave its support Swift 5 and its good. I'm using VMware to run macOS Catalina 10.15 beta I tried to download xcode from the appstore and it won't After that I downloaded the XCode 11.7 from the developer download, and installed it but won't work So I will download another XCode version, but Which XCode version is compatible with macOS Catalina 10.15 beta?

The manifest of installed software is here.

Ruby

The last few releases of Xcode on CircleCI were problematic for Ruby users, due to issues with how Xcode 11 shipped the macOS SDK. This forced us to make some breaking changes with Ruby. My hope is that upgrading to Catalina will resolve these issues, and using Ruby will be more straight forward.

  • The system Ruby that comes bundled with 10.15 is 2.6.3. This is the ruby on the path by default.
  • chruby is installed, and is on the path, and there are two additional versions of Ruby installed, 2.5.7 and 2.6.5.
  • chruby auto-switching is not enabled by default. You can switch it on yourself should you wish.

Shells

Catalina ships with zsh as the default shells, but with CircleCI, the default shell is still bash. By default, commands on macOS run with /bin/bash --login -eo pipefail -c $COMMAND.

Xcode Version For Catalina

You can customize the shell for an executor, job or run command, which will allow you too run a command with zsh, should you wish:
