Why has the error Undefined symbols for architecture arm64 occurred when I used a Mac with M1 chip to compile my project for iOS?

Error code sample:

Undefined symbols for architecture arm64:

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

2. Open your project in Xcode, chooseBuild Settings>Excluded Architectures, and then add the optionAny iOS Simulator SDKwith the valuearm64.
