Ionic v3 Build iOS Stuck at "transpile started"

We have an Ionic v3 Application, we are trying to build that for iOS App Store. Android build is working fine and we have been able to release our apps (apks) to Google Play Store. But for iOS we have been facing challenges. We are trying to build iOS and it gets stuck at transpile started and if we tried a --prod build it will get stuck at ngc started. Verbose does not give any info / error as to where it’s getting stuck.

Happy to share more details if required.
