Unity / XCode – “Unexpected Error” during Build

Unity is a powerful game engine that is widely used by game developers to create games for various platforms. However, sometimes while building a Unity project in Xcode, you may encounter an error that reads “Unexpected Error” causing the build to abort. This error can be frustrating, especially when you don’t know how to fix it.

Fortunately, there is a simple solution to this issue. If you encounter this error, the first step you should take is to perform a “Clean Build Folder” operation. This process clears out any cached files and helps ensure a fresh start to the build process. Here is how to perform this operation:

  1. Open your Xcode project.
  2. Go to the “Product” menu.
  3. Select “Clean Build Folder.”

This will remove all the compiled files and force Xcode to rebuild everything from scratch. Once the process is complete, try building your Unity project again. In most cases, this will resolve the “Unexpected Error” issue.

It’s worth noting that this error can occur due to various reasons, including issues with the Unity project or Xcode itself. In some cases, you may need to investigate the error further to identify the root cause.

If you encounter the error again after performing the “Clean Build Folder” operation, you may want to try some of the following steps:

  • Restart Xcode and try to build again.
  • Verify that your Unity project is up-to-date and that you have not made any changes that could cause issues during the build process.
  • Check your Xcode settings and ensure that they are correctly configured for your Unity project.
  • If you are using any third-party plugins or libraries, make sure they are compatible with your Unity version and Xcode.

In conclusion, if you encounter the “Unexpected Error” issue while building your Unity project in Xcode, don’t panic. Start by performing a “Clean Build Folder” operation to remove any cached files and start fresh. If the error persists, try the additional troubleshooting steps listed above. By following these steps, you can resolve the issue and get back to building your Unity project in Xcode.
