I was using Xcode 11 (dmg downloaded from developer account extra files section) on mac os 10.14.6. Today i updated my Mac os to 10.15 catalina to use xcode 11 canvas view but the issue is after updating to mac os 10.15 Catalina i am unable to open xcode. Configure and build xdebug on macOS Catalina. The reason for these errors is that the /usr/include folder is missing because Apple removed it when they released Xcode 11. But, you can work around this problem. Here is how: First, you need to make sure that Xcode and the command line tools installed. With the Catalina upgrade, my Xcode did not automatically update to 11.1. The App Store kept trying to update Xcode each night through automatic updates. On its own, it never succeeded. Once it reported it could not download Xcode: Unable to Download App. 'Xcode' could not be installed. Please try again later. Xcode 12 release includes Swift 5.3 and SDKs for iOS 14, iPadOS 14, tvOS 14, watchOS 7, and macOS 11.

Xcode 12 beta requires a Mac running macOS Catalina 10.15.4 or later.iOS nine and later, tvOS 9 and later, and watchOS 2.

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.
