Flutter shared_preferences module not found - iOS Xcode build

Question

I am using shared_preferences dependency in Flutter.

Building Xcode (Product->archive - for Generic target) fails with

module 'shared_preferences' not found

I tried flutter clean, flutter pub cache repair, tried moving Flutter lib/ into new project (flutter create .) and I building using older Xcode version (11.4.1)..currently I have 12.0 beta 3.

What is weird is that running in Emulator from my IDE (IntelliJ) works just fine with no errors.

These are my dependencies (pubspec.yaml)

dependencies:
  flutter:
    sdk: flutter
  http: ^0.12.2
  intl: any
  flutter_spinkit: ^4.1.2
  redux: any
  flutter_redux: any
  redux_thunk: any
  shared_preferences: 0.5.1+2

Solution 1

In my case problem was that I was opening Xcode project from Project.xcodeproj instead of Project.xcworkspace.

Solution 2

Searching on Stack Overflow I found this Flutter module not found in Xcode Which links to this https://github.com/flutter/flutter/issues/54599#issuecomment-644336055

This solved it for me!

Solution 3

Product -> Scheme -> Edit Scheme
