Xcode 11.4 Exported SDK do not include x86_64 (Simulator) architecture

I export the SDK for iOS using below command using Xcode 11.4

xcodebuild -workspace ios/jitsi-meet.xcworkspace -scheme JitsiMeet -destination=‘generic/platform=iOS’ -configuration Release archive

When I checklist of architectures in the exported framework it says:

Non-fat file: /Users/umairgillani/Library/Developer/Xcode/DerivedData/jitsi-meet-byuitotfesbuupfgntpadgftdfhq/Build/Intermediates.noindex/ArchiveIntermediates/JitsiMeet/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/JitsiMeet.framework/JitsiMeet is architecture: arm64

Need help to export it for both arm64 as well as for Simulators
