Property with 'retain (or strong)' attribute must be of object type

[hubab00ba]

Description
I installed the library. First problem was during "pod install" - "Specs satisfying the react-native-ffmpeg/https (= 0.5.0) dependency were found, but they required a higher minimum deployment target.", so I set my deployment target to 11. Then I was able to run "pod install" and when I try to start the project from XCode there is an error "Property with 'retain (or strong)' attribute must be of object type".

Expected behavior
Project build without errors.

Current behavior
Project can't build.

Environment

• "react-native": "~0.63.3"

Podfile:

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/react-native-unimodules/cocoapods.rb'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '12'

target 'Example' do
  use_unimodules!
  config = use_native_modules!

  use_react_native!(:path => config["reactNativePath"])

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.
  use_flipper!
  post_install do |installer|
    flipper_post_install(installer)
  end
end

I have the same problem

@christian150590 You can change
@property (nonatomic, strong, readonly) dispatch_queue_t methodQueue;
to
@property (nonatomic, assign, readonly) dispatch_queue_t methodQueue;
in the RTCBridgeModule.h file to make it work but this definitely is not a correct fix.

any update on this ?

@aemre No, but it's related to this - ios/Pods/Headers/Public/React-Core/React/RCTBridgeModule.h:132:1: Property with 'retain (or strong)' attribute must be of object type

i am facing same issue.

Solved: Add pod 'react-native-ffmpeg/full', :path => '../node_modules/react-native-ffmpeg' to your Podfile.

Read more here .

@tanersener Do you know why it was not working with pod 'react-native-ffmpeg', :podspec => '../node_modules/react-native-ffmpeg/react-native-ffmpeg.podspec' as it is shown in the README file?

[tanersener]

It seems like the latest versions of react-native and cocoapods changed the build flags generated for react-native-ffmpeg.

In this issue, the problem is, build flags generated for react-native-ffmpeg include OS_OBJECT_USE_OBJC=0 flag, which is why you get Property with 'retain (or strong)' attribute must be of object type error for a GCD queue object.

I modified the podspec and fixed the issue in v0.5.1. You don't need to use workarounds anymore.
