name: iOS Dev Repo
# Builds an unsigned dev IPA and publishes it together with a freshly-generated
# AltStore source (devrepo.json) to a rolling "dev" prerelease.
#   https://github.com/FTStuff/FTStore/releases/download/dev/devrepo.json
#
# Monorepo: the Xcode project lives in ios/, so every build step runs there.
# app-repo.json stays at the repo root — its raw.githubusercontent URL is what
# users have subscribed to, so it must not move.

        # The Dynamic Island lives in an embedded appex, so an IPA that is wrong
        # about it installs and runs perfectly — the island just never appears,
        # and nothing in the build says why. Every check here is for a way that
        # can happen silently:
        #
        #   missing     the extension is not in the IPA at all. This is what
        #               happened when manager/ shared this build's derived data
        #               (identical project, scheme, target and pbxproj GUIDs)
        #               and its stale-file sweep went after an extension it has
        #               no target for.
        #   wrong id    iOS refuses to load an app extension whose bundle id is
        #               not prefixed by its host app's, and says nothing. The
        #               two ids are built from separate settings in the pbxproj,
        #               so one can drift from the other — and a disambiguator
        #               applied to the app but not the extension does exactly
        #               that.
        #   wrong point a widget extension must declare the widgetkit extension
        #               point. Without it the appex is dead weight.
        #
        # Presence alone was the old check. It passed on all three of these.
