Since iOS SDK build 2.6.105, all iOS SDK included frameworks support both iOS Simulator architecture slices: x86_64 to build on Intel Mac and arm64 to build on Mac M1 and other ARM based Mac.
Therefore, an architectures supported for building on a certain platform should be set in Podfile to use iOS SDK frameworks:
platform :ios, '9.1' use_frameworks! post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings["ONLY_ACTIVE_ARCH"] = "YES" config.build_settings["VALID_ARCHS[sdk=iphonesimulator*]"] = "arm64 x86_64" config.build_settings["VALID_ARCHS[sdk=iphoneos*]"] = "arm64" config.build_settings["VALID_ARCHS[sdk=ipados*]"] = "arm64" config.build_settings["ARCHS"] = "arm64 x86_64" end end end target 'MyObjCApplication' do pod 'FPWCSApi2' pod 'FPWebRTC' end target 'MySwiftApplication' do pod 'FPWCSApi2Swift' pod 'FPWebRTC' end
