Xcode - Hardened Runtime is not enabled

It is also available in Capabilities section

Ok, I found the answer. Hardened Runtime setting available in the Build Settings tab in All build setting section.

Also, If your application containing multiple targets then you need to enable Hardened Runtime for all targets.

1. Enable Hardened Runtime on the Signing & Capabilities screen to cover the app and frameworks.
2. Add --deep flag to Signing - Other Code Signing Flags on the Build Settings screen to cover the direct nested applications inside the frameworks.

3. Add a new run script phase on the Build Phases screen to cover the indirect nested applications inside the frameworks:

   codesign --force --options=runtime \
   --sign "${EXPANDED_CODE_SIGN_IDENTITY_NAME}" \
   "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/Contents/Frameworks/<PATH_TO_THE_APPLICATION>"
