Cannot build Universal framework - iOS

Goals

I'm Developing an universal framework for iOS , which used realmSwift as it dependency install by cocoapod . need to distribute myFramework as universal framework over cocoapod .

Expected Results

The output of universal framework should support and run in all iOS architectures means both device and simulator .

Actual Results

Only build for device architectures , and produce errors :

"could not find module ''RealmSwift" for architecture 'armv7'; found: arm64" "no such module 'RealmSwift'"

Steps to Reproduce

1) Create new empty workspace 2) Add new project ~~> iOS~~ > cocoa Touch framework , and add it to workspace 3) close workspace 4) Open terminal . , go to workspace directory and write touch podfile and open pod file . 5) Add following lines on podfile

workspace 'workspaceName'

use_frameworks!

target 'MyFramework-iOS' do

     platform :ios, '10.0'
     pod 'RealmSwift'
     project 'MyFramework-iOS/MyFramework.xcodeproj'

end

6) pod install 7) open workspace 8) add new Target ~~> cross~~Platform -> Aggregate 9) add new Run script phase 10) add universal framework script 11) build universal framework selected Generic iOS Device
