Build Failed: Undefined symbols for architecture x86_64

The app crashes due to react-native-image-filter-kit, this is the crash log:

Xcode build failed > Error:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_RCTImageView", referenced from:
      objc-class-ref in IFKImageFilter.o
      __OBJC_$_CATEGORY_RCTImageView_$_CacheKey in RCTImageView+CacheKey.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Terminal Error:

The following build commands failed:
        .../Library/Developer/Xcode/DerivedData/MY_PROJECT-dxmgqdxborzhroajvyivtvivrlsi/Build/Products/Debug-iphonesimulator/react-native-image-filter-kit/react_native_image_filter_kit.framework/react_native_image_filter_kit normal x86_64
(1 failure)

react_native_image_filter_kit was installed properly based on documentation via: pod install

what I’ve done to fix the issue with no success:

• Upgrading macOs from Mojave to Catalina
• Upgrading Xcode from 10.2 to 11.4
• Adding javaScriptCore.framework > Build Phases > Link Binary and Libraries (for both my_project & my_projectTests)

That error means that native part of the module can’t be accessed - e.g. it was not installed properly.

Add this line in your react-native-image-filter-kit.podspec , this file exist in node_modules / react-native-image-filter-kit s.static_framework = true your entire file should be :

require 'json'

package = JSON.parse(File.read(File.join(__dir__, 'package.json')))

Pod::Spec.new do |s|
  s.name             = package['name']
  s.version          = package['version']
  s.summary          = package['description']
  s.homepage         = package['homepage']
  s.license          = package['license']
  s.author           = package['author']
  s.platform         = :ios, '9.0'
  s.source           = { :git => 'https://github.com/iyegoroff/react-native-image-filter-kit.git', :tag => 'v#{s.version}' }
  s.source_files     = 'ios/**/*.{h,m}'
  s.resource_bundles = { 'bundle' => ['ios/Resources/*.cikernel'] }
  s.requires_arc     = true

  s.dependency 'React'
  s.static_framework = true
  s.dependency 'Bolts/Tasks', '1.9.0'
end

don’t forget : cd ios && pod install
