Enabling Mac Catalyst pulled in the iPad device family, which made App Store
Connect reject the iOS build with error 90474: an iPad-capable bundle must
declare all four interface orientations to support iPad multitasking, and this
app declared two.
Catalyst genuinely needs the iPad idiom, but only for its own build. A per-SDK
condition gives macOS family 2 while iOS keeps family 1 — verified to resolve
correctly for both destinations, and Catalyst still builds with family 2 alone.
The shipped iOS bundle is back to UIDeviceFamily [1], exactly as before the
port started.
The iPad orientation key is removed rather than extended. With an iPhone-only
iOS build it is ignored, and macOS ignores orientation keys entirely, so it was
dead configuration that only served to trip the validator.
Supporting iPad properly is a deliberate piece of work — the layout is
portrait-only with no size-class handling — and is better done on purpose than
inherited as a side effect of the Mac port.
Verified: builds for both Mac Catalyst and iOS Simulator; built bundle reports
UIDeviceFamily [1] and portrait-only with no iPad orientation key.
