Xcode – library not found for -lBVLinearGradient

I’ve moved to Macbook Pro M1, and my Xcode version is 12.5.1

When running my app, I’m getting below error:

ld: library not found for -lBVLinearGradient
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I’m also using react-native-linear-gradient (version 2.5.6) library, for which this error is related to.

    I could fix this issue with amend my Podfile by adding this:

    post_install do |installer|
  ## Fix for XCode 12.5
  find_and_replace("../node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm",
 "_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules", "_initializeModules:(NSArray<Class> *)modules")
 find_and_replace("../node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm",
 "RCTBridgeModuleNameForClass(module))", "RCTBridgeModuleNameForClass(Class(module)))")
end

def find_and_replace(dir, findstr, replacestr)
  Dir[dir].each do |name|
      text = File.read(name)
      replace = text.gsub(findstr,replacestr)
      if text != replace
          puts "Fix: " + name
          File.open(name, "w") { |file| file.puts replace }
          STDOUT.flush
      end
  end
  Dir[dir + '*/'].each(&method(:find_and_replace))
end

    When I did the following steps, I was able to build without any errors

    1. Paste these lines at the bottom of the pod file

    post_install do |installer|
  find_and_replace("../node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm",
 "_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules", "_initializeModules:(NSArray<Class> *)modules")
 find_and_replace("../node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm",
 "RCTBridgeModuleNameForClass(strongModule))", "RCTBridgeModuleNameForClass(Class(strongModule)))")

 installer.pods_project.build_configurations.each do |config|
  config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
 end
end

def find_and_replace(dir, findstr, replacestr)
 Dir[dir].each do |name|
     text = File.read(name)
     replace = text.gsub(findstr,replacestr)
     if text != replace
         puts "Fix: " + name
         File.open(name, "w") { |file| file.puts replace }
         STDOUT.flush
     end
 end
 Dir[dir + '*/'].each(&method(:find_and_replace))
end

    2. You have to exclude arm64 for simulator architecture both from your main project and the Pod project

    Main Project
    enter image description here

    Pod Project
    enter image description here

    3. Delete DerivedData

    rm -rf ~/Library/Developer/Xcode/DerivedData/

    4. Rebuild node_modules and pod install

    rm -rf node_modules/ && rm -rf ios/Podfile.lock && rm -rf package-lock.json && rm -rf yarn.lock
yarn
cd ios/ && pod install && cd ..

    If there is nothing I forgot, everything was working when I did all these. It took me a long time to put these pieces together but it turned out nice
