This article provides a systematic technical analysis of common CocoaPods dependency version conflicts in Flutter development, particularly focusing on compatibility errors involving components such as Firebase/Core, GoogleUtilities/MethodSwizzler, and gRPC-Core. The paper first deciphers the underlying meaning of error messages, identifying the core issue as the absence of explicit iOS platform version specification in the Podfile, which leads CocoaPods to automatically assign a lower version (8.0) that conflicts with the minimum deployment targets required by modern libraries like Firebase. Subsequently, detailed step-by-step instructions guide developers on how to locate and modify platform version settings in the Podfile, including checking version requirements in Local Podspecs, updating Podfile configurations, and re-running the pod install command. Additionally, the article explores the applicability of the pod update command and M1 chip-specific solutions, offering comprehensive resolution strategies for different development environments. Finally, through code examples and best practice summaries, it helps developers fundamentally understand and prevent such dependency management issues.
