This error indicates that your project is attempting to use a deprecated reference, DT_TOOLCHAIN_DIR, which is no longer compatible in the context of Xcode 15.0. As a result, your app fails to run, and you may feel stuck.

The Solution

Fortunately, resolving this issue involves making changes to your project's configuration files. The solution can be executed in a few steps, utilizing a post_install modification in your Podfile. Here’s how you can do it:

Step-by-Step Instructions

Explanation of the Code:

post_install do |installer|: This block allows you to define modifications to be executed after the installation of the pods is complete.

installer.pods_project.targets.each do |target|: This line retrieves all the targets within your pods project, so you can modify each one.

flutter_additional_ios_build_settings(target): Applies additional Flutter-specific build settings to each target.

The loop through target.build_configurations.each do |config| allows us to access the build configurations and modify them.

gsub: This Ruby method replaces occurrences of DT_TOOLCHAIN_DIR with TOOLCHAIN_DIR in the configuration files.

Save and Reinstall Pods:

After modifying your Podfile, save the changes.

Open the terminal, navigate to your project directory, and run the command:
