I am encountering an error when trying to build my Flutter iOS app for the simulator using CocoaPods. The build fails with the following error message:

bash

Copier le code

Error (Xcode): Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibility56
Could not build the application for the simulator.

Despite following the recommended steps to resolve this issue, the error persists.

Environment

  • Flutter Version: 3.22.2
  • Xcode Version: 14.2.0
  • CocoaPods Version: 1.11.2
  • iOS Deployment Target: 15.0
  • Swift Version: 5.0

Steps Taken to Resolve the Issue:

  1. Updated iOS Deployment Target to 15.0:
  • Modified Podfile to set platform :ios, '15.0'.
  • Updated Xcode project settings to set iOS Deployment Target to 15.0.
  1. Cleaned and Reinstalled Dependencies:
  • Ran flutter clean.
  • Deleted Pods and Podfile.lock.
  • Ran pod install.
  1. Verified Compatibility of Dependencies:
  • Checked all dependencies to ensure they are compatible with Swift 5 and iOS 15.0.
  1. Modified Build Settings in Xcode:
  • Ensured Swift Language Version is set to 5.0.
  • Added $(inherited) to Framework Search Paths and Other Linker Flags.

Despite these steps, the issue persists. Any help or suggestions would be greatly appreciated.

Error Logs:

You might have better luck asking this over at the Apple developer forums or somewhere appropriate to CocoaPods.
