# manager/ is a fork of this tree: same project file name, same scheme, same
# target name, and — because it was forked rather than recreated — the same
# pbxproj GUIDs. Xcode's build database is keyed on those GUIDs, so pointing
# both products at $(TMPDIR)/FTStore leaves it unable to tell them apart. Only
# SRCROOT differs, and that is not enough: the Manager build had no
# FTStoreActivity target then, so it treated this app's Live Activity extension
# as a stale file and tried to delete it, while this build found the Manager's
# object files sitting in its own intermediates. The result was an IPA whose
# embedded FTStoreActivity.appex was a leftover from some earlier build and no
# longer matched the app around it, which is exactly what the Dynamic Island
# needs in order to render anything.
#
# The Manager has an FTStoreActivity of its own now. That does not make a
# shared derived-data path safe again — it makes the two extensions collide by
# name as well, so each build would take the other's.
#
# It never showed on the GitHub-hosted runners because every job got a fresh VM
# and therefore an empty $(TMPDIR). On the self-hosted Mac the directory
# survives between runs *and* between products, so the two builds trampled each
# other every time.

# `Package.resolved` is the build, and the flag below is what makes that true.
#
# Nothing here changed and the build broke anyway: BitByteData published 2.1.0,
# which raises its own floor to iOS 17, and SWCompression asks for it with an
# open `from: "2.0.0"`. Xcode resolved past the committed pin of 2.0.4, took the
# new one, and then refused the graph it had just built — SWCompression's own
# manifest says iOS 11, so a dependency needing 17 cannot go under it. The app's
# deployment target is not part of that arithmetic and raising it fixes nothing.
#
# `-onlyUsePackageVersionsFromResolvedFile` forbids the drift instead of
# reacting to it: every version comes from the checked-in file, and a dependency
# missing from it fails the build rather than being invented. The cost is that
# adding or moving a package means resolving it in Xcode and committing the
# result, which is the point.
