Hello Aswhin,
are you using a Mac or a Windows machine?
If you are using a Mac you have already the option if you have installed the HAT on it.
On a Windows machine it is not possible with local tools. But SAP works on a Cloud build service which does the build process in the cloud w/o the need of any local tools. With that you can also create the .ipa files on Windows machines in future. At the moment the service is not yet released.
Regards,
Florian
