I don't want to publish anything on the app store. It should not cost 100 dollars per year (or 3000 dollars over 30 years) just to have the privilege to install some hobby projects on my iPhone or iPad.
You pay that price in order to access the SDKs, app signing, developer community, app review, app hosting on the app store (even if you don't want to use it), test flight. Apple offers a lot of service for a (honestly) decent price.
