Add support for AltStore PAL to release in EU

[XylotoGhost]

Hi,

I was wondering if it was possible to publish the App in AltStore PAL. AltsStore is an alternative app store for iOS available in the European Union.

To support AltStore PAL, you need to provide a hosted .json document with metadata about the apps you publish in AltStore. In theory, Github can be used for this and no additional webhosting should be necessary.

I created a basic Altsource definition for the project, which you can view at the end of the thread. There are some to-dos missing, which I cannot do or do not know enough about.

• Adding Marketplace ID (Required): Apple requires a marketplace setup and notarization of the app, similar to MacOS.
• Adding used permissions / entitlements: AltStore enforced privacy policies in terms of used permissions and entitlements in the app. Metadata will be checked against submitted .ipa

Supporting your app in AltStore PAL would provide an additional distribution way, possibly faster and more open than Apple's AppStore. It can also provide the possibility of publishing AmpFin for free, as AltStore /Epic Games covers the fees imposed by Apple for app publishing.

Edit: Added additional context for better understanding.
