iOS build pipeline taking more than 50 minutes

I've Created below YAML for iOS Build Pipeline for Monorepo environment and Reactive as frontend. Pipeline is taking so much of time (Nearly 57 minutes) in Azure Devops, specially build step taking 39-43 minutes. Please help to reduce the pipeline build time.

    - group: resfebervariables   #Variable name where certificate password has been saved.
