[Bug]: [iOS] FBAudienceNetwork In Podfile Is Too Old

by ADMIN 53 views

Introduction

As a developer, I'm facing a dependency conflict with FBAudienceNetwork in my project. The issue arises from the version constraint specified in the library's Podfile, which is too restrictive and prevents successful integration via CocoaPods. In this report, I'll outline the current behavior, expected behavior, and steps to reproduce the issue.

Current Behavior

The library's Podfile specifies FBAudienceNetwork '6.16'. However, my project requires FBAudienceNetwork '6.17.1', which leads to a conflict and prevents successful integration via CocoaPods. This conflict is a common issue in dependency management, and a more flexible version constraint would greatly improve compatibility with other projects and their dependencies.

Expected Behavior

To resolve this issue, I kindly request that the version constraint for FBAudienceNetwork be changed to a more flexible option, such as:

  • ~> 6.16 (allows compatible patch versions)
  • >= 6.16 (allows any version 6.16 or higher)

Using a less precise version constraint would enable my project to successfully integrate with FBAudienceNetwork '6.17.1' and other compatible versions.

Steps to Reproduce

To reproduce this issue, follow these steps:

  1. Create a new project using CocoaPods.
  2. Add the FBAudienceNetwork library to the project's Podfile.
  3. Specify the version constraint as '6.16' in the Podfile.
  4. Run pod install to install the dependencies.
  5. Attempt to integrate FBAudienceNetwork '6.17.1' into the project.

Platform

The issue is reproducible on the following platforms:

  • macOS 15.4.1
  • Xcode 16.3
  • Flutter 3.29.3
  • Dart 3.7.2

Conclusion

Q: What is the current version constraint for FBAudienceNetwork in the library's Podfile?

A: The current version constraint for FBAudienceNetwork in the library's Podfile is '6.16'.

Q: Why is the current version constraint causing a conflict with my project?

A: The current version constraint is too restrictive and prevents successful integration via CocoaPods. Your project requires FBAudienceNetwork '6.17.1', which is not compatible with the version constraint '6.16'.

Q: What is the expected behavior for the version constraint?

A: The expected behavior is to change the version constraint to a more flexible option, such as:

  • ~> 6.16 (allows compatible patch versions)
  • >= 6.16 (allows any version 6.16 or higher)

Q: How will changing the version constraint improve compatibility with other projects and their dependencies?

A: Changing the version constraint to a more flexible option will enable your project to successfully integrate with FBAudienceNetwork '6.17.1' and other compatible versions. This will improve compatibility with other projects and their dependencies.

Q: What are the benefits of using a more flexible version constraint?

A: Using a more flexible version constraint has several benefits, including:

  • Improved compatibility with other projects and their dependencies
  • Reduced risk of version conflicts
  • Easier maintenance and updates of dependencies

Q: How can I reproduce the issue with the current version constraint?

A: To reproduce the issue, follow these steps:

  1. Create a new project using CocoaPods.
  2. Add the FBAudienceNetwork library to the project's Podfile.
  3. Specify the version constraint as '6.16' in the Podfile.
  4. Run pod install to install the dependencies.
  5. Attempt to integrate FBAudienceNetwork '6.17.1' into the project.
