Xcode – "Undefined symbol: protocol descriptor for Swift.ExpressibleByFloatLiteral" issue while installing react native on macOS Big Sur

I was trying to install React Native on my system, and found that it failed to install CocoaPods dependencies which is required by that template error.

sudo arch -x86_64 gem install ffi fixed this issue but ended up with event-config.h" file not found error.

I changed the changed the flipper version in pod file to use_flipper!({'Flipper'=>'0.76.0'}) and then I reached to the error mentioned above. Any help on this issue would be appreciated.

node version : 15.10.0
react-native version: 0.63.4
Xcode version: 12.4

    I managed to resolve this issue by adding an empty swift file to the project in Xcode. This had the side effect of creating a bridging header file which (for me at least) got my project to compile.

    You need to exclude architecture arm64 if you are using M1 mac.
    Please check this image

    Also add this code at the end of the pod file

    post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings["ONLY_ACTIVE_ARCH"] = "NO"
      end
    end
  end

    Do pod install, Clean the build folder and restart the build it will resolve the issue.

    Update: for xCode 13 use the following configurations:
    if you are facing Command PhaseScriptExecution failed with a nonzero exit code in react native xcode 13

    This is caused because your project contains frameworks/libraries of both Swift and Objective c.

    Add a swift file(If you see Objective C files already in your project) or Objective C file(If you see Objective C files already in your project). Select the targets those give above error.

    This step will ask to create a bridging header. Create bridging header
    Say yes and compile and run.

    What really worked for me, only add this Excluded Architectures and you will be fine, if you are using a Mac with M1 of course

    What ended up working for me is removing the LIBRARY_SEARCH_PATHS from Xcode…

    When using Dipan Sharmas solution I couldn’t build for devices or "Any iOS Device" anymore. What resolved this issue for me was just excluding arm64 for the "Any iOS Simulator SDK" instead of excluding it in the upper level. Even removing arm64 from the upper level of excluded architectures, did not get the project building again for Devices and "Any iOS Device". Had to pull an older project file from my git.

    If you are on m1 Mac

    • run arch -x86_64 pod install in iOS folder
    • run Xcode with Rosetta
    • clean build
    • run again

    Dipan’s excellent answer initially worked for but then because of forces beyond my control, I had to update a bunch of React libraries and it no longer worked.

    Eventually I was able to solve this problem by removing the two references to

    ""$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)""

    in <my project name>.xcodeproj/project.pbxproj file. I then ran my project again and it got through the last few files.

    NOTE: In the interest of full disclosure, I don’t know what the ramifications of this change will be
