Since Xcode 26.1, actool ignores an .appiconset that shares its name with
an Icon Composer .icon and renders the icons for older OS versions from the
.icon instead. The undocumented --enable-icon-stack-fallback-generation flag
that used to turn this off is now parsed and discarded, so building with
Xcode 27 replaced our flat icons with generated ones on macOS 12-15, where we
prefer our own low resolution art.
Replacing AppIcon.icns is not enough because macOS reads the icon from
Assets.car before Tahoe as well. Instead compile AppIcon.appiconset into its
own catalog and merge its renditions into the built Assets.car with CoreUI,
leaving the icon stack renditions that macOS 26 uses in place.
The rendition format is undocumented, so the merge fails the build if the
catalog does not look the way we expect, and checks that the icons still
decode after writing.

Now that the deployment targets are iOS 15 and macOS 12, every guard,
fallback and workaround for an older release is dead code that only
obscures what the supported path is. Remove them:
- Drop the `@available` attributes for iOS 15, macOS 11 and macOS 12, and
unwrap the matching `#available`/`#unavailable` guards in Swift and the
`@available`/`API_AVAILABLE`/`NS_AVAILABLE_IOS` ones in Objective-C.
- Delete the legacy-only views and helpers left unreachable by that:
NumberTextFieldOld, VMConfigNetworkPortForwardLegacyView,
VMContextMenuModifier.bodyBigSur, the nonbrokenSheet, uniqued,
customBadge, borderedList and legacySettingsToolbar shims, the
.unsupported BootloaderSelection case, and the iOS 14 sacrificial
version Section in the QEMU settings list.
- jb_has_cs_execseg_allow_unsigned() has returned false for every host
since iOS 14.4, so drop it along with the is_device_A12_or_newer()
helper that only it used. The entitlement parser no longer needs to
copy the blob either, since that copy existed only so the psychic paper
needle could be blanked in place.
- VMDisplayTerminalViewController tracked the keyboard frame by hand for
iOS 14. `useAutoLayout` is a constant that cannot be overridden, so
nothing ever registered the notification observers and only the
keyboardLayoutGuide path is reachable.
- VMConfigQEMUView's additionalArguments is now referenced on iOS only,
which leaves its macOS branch, and the macOS 11 ForEach crash
workaround inside it, unreachable.
- Raise the Cydia package floor and the postinst/prerm helpers to match
the new minimum.
Two of the removed guards dropped an error path rather than just a
branch. The shared directory `featureNotSupported` throw covered
VZVirtioFileSystemDeviceConfiguration and friends being macOS 12+, which
no longer applies to any supported host. The macOS guest
`platformUnsupported` throw when decoding a boot config on Intel only
fired on macOS 11; the Apple Silicon requirement it really guards is
enforced unconditionally in
UTMAppleConfigurationSystem.fillVZConfiguration, which both the start and
the save path go through.

Xcode 27 no longer supports deploying to iOS 14 or macOS 11, and the
macOS 27 SDK breaks several dependency builds, so raise the minimum
versions and fix the dependency build:
- Bump IOS_SDKMINVER/MAC_SDKMINVER and the project deployment targets.
- Pass our deployment targets to the Hypervisor build, whose project
still targets iOS 14.
- Build ANGLE without -Werror; new clang warnings break it.
- Update MoltenVK to pick up the upstream minimum target bump and set
a visionOS minimum so it no longer inherits the SDK version.
- Patch QEMU apple-gfx to use PGCreateDeviceWithDescriptor, since
PGNewDeviceWithDescriptor is no longer exported by the macOS 27 SDK.
- Skip copying the IOKit headers on macOS where they are already in the
SDK and a second copy conflicts with the IOKit module.
- Export MACOSX_DEPLOYMENT_TARGET since libtool drops -target when
linking C++ libraries, which built libasprintf for macOS 27.
- Default CI to the installed Xcode.

The scripting-targets entitlement names the target app as a dictionary key built from $(PRODUCT_BUNDLE_PREFIX:default=com.utmapp). Xcode expands it only when it signs, and the unsigned package re-signs from the raw file, so utmctl in an unsigned build was allowed to script an app with that literal name and no other: every command failed with "failed to get scripting definition" and an unrecognized selector. Expand the key before signing.
Concurrent build_dependencies.sh runs on the same CI runner get rate
limited by GitHub, so clones and fetches fail intermittently. Retry each
network operation with exponential backoff, jittered by PID so parallel
builds do not retry in lockstep.
The tree:0 filtered clones lazily fetch objects during checkout and
submodule update, so those hit the network too and are retried as well.
Add -f to curl so that a rate limited response is treated as a failure
instead of being saved as the tarball.

The macOS build embeds D3DMetal.framework when the sysroot ships it, but
the framework is distributed separately and cannot be committed. When
D3DM_DIST_DMG_URL is set, fetch the distribution DMG and stage the
framework into the universal sysroot before it is packed into the
artifact and saved to the cache, so downstream builds pick it up. Builds
without the variable set are unaffected.
We cannot ship a com.apple.* bundle, but D3DMetal loads its own
default.metallib through [NSBundle bundleWithIdentifier:@"com.apple.D3DMetal"]
using that identifier as a literal compiled into the framework binary, so
the rebrand rewrites both the Info.plist and the binary. Rewriting only one
makes the lookup return nil and every D3DMetal process aborts in
-[MTLDevice newLibraryWithFile:nil error:].
Staging lives in scripts/install_d3dmetal.sh so it can also be run by hand.

- virglrenderer uses shmem for texture import/export so we need App Group for both iOS and macOS
- Add QEMURenderServer for new process model rendering (both Venus and Neptune)
- macOS: add DXMT and D3DMetal-Native backends
- We require 8G hostmem for Neptune but iOS currently fails > 256M
