...that I can use for free to build a Mac app that won't run without security warnings, or to test in a simulator -- otherwise I have to pay $100/yr. The 30% tax brings no value.
If you have a design/image creation software and XCode you could make almost any app.
Patreon doesn’t give any tools to creators to directly create.
