What does this PR do?

Adds macOS as a build target for xtool dev, on macOS and Linux hosts:

• Build contract: xtool.yml version: 2 selects a macOS target and deploymentTarget. Products can be executables, libraries or prebuilt binaries. Nested products are helper executables, app extensions and XPC services. --triple arm64-apple-macosx<version> overrides the schema.
• Planning and linking: platform-specific products and resources. Each package compiles for its own declared minimum, as with swift build, while binaries record the app's deployment target through -platform_version. Per-product rpaths, entry points and -platform_version go through the toolset linker section, so compile commands stay identical across products.
• Bundle assembly: standard Contents/ layout, with helpers in Contents/Helpers and frameworks, XPC services and extensions in their Xcode locations. SwiftPM resource bundles are relocated with a Bundle.module accessor that works after the build directory is gone. Shared helper dependencies are coalesced, and an rpath audit catches libraries that system rpaths would hide.
• Deferred signing handoff: --defer-signing writes xtool/<App>.app, <App>.signing.json and copied entitlements.
• On a Mac: xtool dev sign (ad-hoc, Apple Development, Developer ID by certificate fingerprint), xtool dev notarize (existing notarytool keychain profile, resumable), xtool dev run.
• Linux cross-compile: versioned macOS triples work with the Darwin Swift SDK through a generated single-target destination.
• Editor tooling: the build server and LSP config follow the selected platform, and the build server starts without running the planner.

macOS defaults to the SwiftPM native backend. SwiftBuild is rejected for macOS, and iOS keeps its existing backend selection and unversioned triple.

Documentation: Documentation/xtool.docc/MacOS.md, plus Control.md for the schema.

Upstream PRs that overlap

Checked against the 41 open PRs on 2026-10-19, after rebasing onto main at 8c46156. The six commits merged since the previous base (#349, #367, #361, #306, #328, #340) rebased without conflicts.

Same feature area (expect a design conflict):

• build: support tvOS and Mac Catalyst targets #362 tvOS and Mac Catalyst targets (opened 2026-10-16, +1010/−119). It also plans macOS apps with the Contents layout, picks device families and resource paths per platform, and stamps the SDK version into Mach-O headers. It shares 6 files with this branch: BuildSettings.swift, Planner.swift, Packer.swift, DevCommand.swift, PlannerTests.swift and Control.md. Both PRs define how xtool represents a platform; one should be rebased onto the other's abstraction, or the abstraction should be agreed first.
• Add experimental standalone watchOS builds, signing, and deployment probe #350 watchOS builds. It adds another platform through the same knobs: platform selection in PackSchema, Planner, Packer, BuildSettings and XcodePacker, --platform on xtool new/dev, and the BSP/LSP config. It shares 10 files with this branch.

With #350, #362 and this PR, three platforms are in flight at once. The platform abstraction should be designed once.

Same code, different bug (expect rebase conflicts):

• packer: keep main in app extensions #320 keep _main in app extensions and packer: pass -isysroot to clang when linking #321 pass -isysroot when linking (Linux builds record the deployment target as the SDK version in LC_BUILD_VERSION (no -isysroot at link time) #351, iOS fix). Both edit the linker flags in Packer.swift that this branch moved into Plan.Product.linkerArguments and the toolset linker section (9754968). packer: keep main in app extensions #320 also introduces a competing Plan.Product.linkerFlags. packer: pass -isysroot to clang when linking #321 solves Linux builds record the deployment target as the SDK version in LC_BUILD_VERSION (no -isysroot at link time) #351 for iOS with -isysroot; this branch solves it for macOS with -platform_version. The two approaches should be unified.
• PackLib: embed each dynamic library only once #291 embed each dylib once, PackLib: link embedded dynamic libraries into the app #292 link embedded dylibs into the app, Keep extension dynamic libraries in the host app #295 keep extension dylibs in the host app. iOS fixes in Planner/Packer, close to fa253eb (coalesce shared helper dependencies, macOS helpers only) and 7fe0655 (rpath audit). Neither side fixes the other's problem. The conflicts are in Planner.swift, which this branch changes substantially.
• Fix Sentry package bugs: name mismatch and FAT static detection #198 fat static detection for Sentry (Issues using the Sentry package #130). The same idea as 441fcd2, applied to the iOS path. The detection logic could be shared.
• build-server: real source paths for SourceKit-LSP #302 build-server proxy for symlinked sources. Touches DevBSPCommand.swift, which 6c17f78 (start the build server without the planner) also changes.
• Add support for running XCTest/XCUITest on-device #236 XCTest/XCUITest on device. Touches Packer.swift and Planner.swift; file conflicts only.

File conflicts only:

• packer: embed entitlements in simulator binaries like Xcode #309 simulator entitlements, packer: preserve user Info.plist capabilities #322 Info.plist capabilities, packer: stamp Apple build keys (DT*) from the SDK #323 DT* build keys, PackLib: copy root Package.resolved into the builder package #290 copy Package.resolved, packer: compile asset catalogs with AssetKit #325/feat: asset catalog (.xcassets) compilation #219 asset catalogs, Add --jobs to dev build and dev run #358 --jobs, Hot reloading #227 hot reloading.
• packer: stamp Apple build keys (DT*) from the SDK #323 and packer: compile asset catalogs with AssetKit #325 are iOS packaging features macOS will want too: DT* keys for App Store uploads, and .xcassets compilation. f475a3c and 816e5c6 only copy raw assets uncompiled.
• signing: sign for distribution with an existing identity #326 distribution signing with an existing identity. The same problem space as d7f0a3d (macOS Developer ID signing), but iOS-only. It also touches DevCommand.swift.

#327, #342, #297, #238 and #143 touch only Package.swift or Control.md. The remaining 17 open PRs (auth, 2FA, setup/download, Windows host SDK, device registration, wireless deploy and similar) share no files with this branch.

How was it tested?

• Unit tests: swift test with Swift 6.4 runs 151 tests in 13 suites, all passing. make lint is clean.
• Real build tests: on macOS the suite compiles and runs disposable packages to check Bundle.module lookup after the build directory is removed, for debug and release.
• CLI tests: the Bats suite in integration-tests/suite exercises the public CLI, and CI runs it on macOS (53f9b23).
• Open-source apps: two popular macOS apps built from their own Package.swift. Only an xtool.yml and an Info.plist overlay were added; no app sources changed. Each was ad-hoc signed with xtool dev sign and passed codesign --verify --deep --strict. Each bundled CLI was run with --version.
  • AeroSpace v0.21.3-Beta: the app plus the aerospace CLI helper.
  • CodexBar 278e905: the app plus two helpers. Sparkle is embedded with its XPC services, and six SwiftPM resource bundles are relocated.
  • With the 13.0 floor, both build at their declared minimums (13.0 and 14.0) and record them as minos.

Build time against xcodebuild

Release, arm64, signing deferred. M1 Max, 10 cores, 32 GB, Xcode 26.6.

App	Scenario	swift build	xcodebuild	xtool
AeroSpace (median of 3)	clean	—	186.8 s	95.1 s
	no-op	—	8.3 s	7.5 s
	one file touched	—	29.6 s	46.2 s
CodexBar (xtool: 2 rounds)	clean	421.5 s	427.2 s	422.0, 418.5 s
	no-op	3.3 s	8.1 s	7.4, 7.4 s
	one file touched	122.7 s	125.2 s	123.2, 123.0 s

• AeroSpace ran under heavy CI load, so its timings are indicative only; it has no SwiftPM resource bundles. The CodexBar runs were near idle (1-minute load 1.8–3.2, no CI jobs).
• The CodexBar comparison pits upstream's own build step (swift build per product) and xcodebuild on the package schemes against xtool at 9bd8593. The widget and signing are excluded on every side.
• Clean builds do different work. xcodebuild builds explicit Clang modules, a dSYM and the asset catalog; SwiftPM does none of these.
• xtool's fixed cost: package inspection, planning and assembly take 4–17 s per invocation. That cost dominates no-op and single-file rebuilds.
• Each module compiles once. xtool adapts SwiftPM's generated Bundle.module accessors through a -vfsoverlay. Earlier revisions of this branch compiled modules with resource bundles twice: on every build before 42cce46 (CodexBar no-op: 729.1 s), and on clean builds before 9bd8593 (CodexBar clean: 778.0 s). xtool now plans first (--print-manifest-job-graph), so the accessors exist and are adapted before the first compile.

Known limitations

• Inspection cost on every build: show-dependencies, plus describe and dump-package per package, runs even for no-op builds. Caching it by manifest and Package.resolved hashes is a follow-up.
• Raw assets stay uncompiled: raw asset catalogs inside a dependency's SwiftPM resource bundle are copied as SwiftPM built them, so their images don't load at runtime. The same raw inputs supplied through xtool.yml are rejected.
• Not supported: universal binaries; Debug builds on Linux (SwiftPM needs codesign); SwiftBuild for macOS; Mac Catalyst.
• Shipped binaries keep SwiftPM's build-host toolchain rpath after /usr/lib/swift.

Design decisions

• macOS builds use SwiftPM's native backend; SwiftBuild is rejected for macOS. SwiftBuild applies a versioned --triple as every package's deployment target, so a dependency that declares a lower minimum compiles at the app's target and fails on APIs obsoleted there. The unversioned triple doesn't help: without a version, SwiftBuild builds Release universal, and on Linux it then has no way to build a single architecture. Native SwiftPM compiles each package at its own minimum and cross-compiles from Linux today.
• xtool adapts SwiftPM's generated Bundle.module accessor instead of replacing it. The native accessor looks next to the executable and then at an absolute build-machine path, so a signed .app would only find its resources on the machine that built it. A -vfsoverlay substitutes an adapted copy that also searches Contents/Resources, as Xcode's accessor does. Package sources are not edited, and toolchain changes to the generated file are picked up or rejected rather than silently replaced. A plan-only run generates the accessors before the first compile, so builds cost the same as swift build (see the CodexBar numbers above).
• iOS is unchanged. It keeps its backend selection (SwiftBuild from Swift 6.4) and its unversioned triple. xtool therefore uses two backends, one per platform. A SwiftBuild spike built, signed and relocated CodexBar on a Mac, so macOS can move to SwiftBuild once it can build one architecture with each package at its own minimum.

Open question for the maintainer

With #350 (watchOS) and #362 (tvOS, Mac Catalyst), three PRs each add platforms to PackSchema, Planner, Packer and BuildSettings. Which platform abstraction should they share, and in which order should they land?

Definition of done

• macOS apps build from SwiftPM on Mac and Linux hosts, with the deferred-signing handoff and dev sign / dev notarize / dev run on a Mac
• No iOS regression: SwiftBuild keeps the unversioned triple (a3f98bb), and each package compiles at its own minimum (b94217d)
• Correctness issues found while testing real apps are fixed: raw assets in dependency bundles (816e5c6), deployment floor (19b30b0)
• Known limits are documented in MacOS.md and above
• CI green on this PR
• Order and shared platform abstraction agreed with Add experimental standalone watchOS builds, signing, and deployment probe #350 and build: support tvOS and Mac Catalyst targets #362

Provide resolved pins for the generated wrapper package.

When a .library product is wrapped, the generated manifest declares the root package as a local dependency. The wrapper build then uses xtool/.xtool-tmp as its package root with --disable-automatic-resolution. If the root dependency graph contains remote packages, SwiftPM can fail because it cannot find a resolved file for the wrapper package, or because that file is out of date.

Create a wrapper-compatible Package.resolved before this invocation. If copying the root file produces an invalid v3 originHash, allow automatic resolution for the wrapper invocation instead. Keep the root package's resolved file unchanged.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

For SwiftBuild iOS targets, do not pin the versioned compiler triple in the BSP configuration.

The BSP branch always writes target.compilerTriple, for example arm64-apple-ios17.2, into the build-server argv. EditorTarget.serverSettings then builds BuildSettings(triple: request.triple) with that versioned triple. On Swift 6.4, iOS defaults to .swiftBuild. For SwiftBuild, withTarget deliberately keeps ["--triple", triple] unchanged.

The comment in BuildSettings.withTarget (lines 152–154) explains the risk. SwiftBuild applies a versioned triple's deployment target to every package. Dependencies then compile for the app's minimum instead of their own.

• Builds avoid this problem.
• The editor build server now has it.
• Example: a dependency declares a backport obsoleted: below the app's minimum, as swift-perception does. The index build then reports errors that xtool dev build does not report.
• The previous static BSP file passed no --triple, so this is a regression for iOS editor users.

Pin the versioned triple only where it is safe. The macOS SwiftPM path is safe because SwiftPM receives the version separately through --triple with --swift-sdk. For iOS, use the target's unversioned identity. isGenerated already accepts any valid pinned triple, so existing generated files are still recognized.

🛠️ Proposed fix

             path = Self.bsp.0
             // Pin the planned deployment version so starting the server needs no package inspection.
-            object = bspObject(triple: target.compilerTriple)
+            // SwiftBuild (the iOS default) would apply a versioned triple to every package.
+            let pinned = target.platform == .macOS ? target.compilerTriple : target.triple
+            object = bspObject(triple: pinned)

Update the BSP branch in the target configuration logic to pass the versioned
target.compilerTriple only for macOS; for non-macOS targets such as SwiftBuild
iOS, pass the unversioned target.triple to bspObject. Preserve the existing BSP
path and generated-file recognition behavior.

Update: restructured history, a build fix, and fewer SwiftPM calls

I force-pushed feat/macos-support (9758181 → 9683d82). The branch is now a series of focused commits on main. Cleanup is folded into the commits that introduced the code instead of being stacked on top.

Cleanup

• Formatting of SDK identities and compiler triples, the macOS Swift SDK lookup, and validation of single path components each live in one place.
• The bundle audit reuses MachOBinary's CPU and platform constants.
• The editor configuration (LSP/BSP) reuses the plan the build already made, instead of inspecting the package a second time.
• Mac host tools run through one MacHostClient dependency, replacing the separate signing and run clients.
• Manifests, receipts and the signing dry-run share one sorted, pretty-printed JSON encoder.

Behaviour changes

• Restricted entitlements are rejected at handoff (d9faa36). xtool dev build --defer-signing now rejects provisioning-dependent entitlements (for example com.apple.developer.homekit or keychain-access-groups) and malformed entitlement files on the build machine. Previously this only happened at signing time. The signer still rejects them if a handoff is edited afterwards. README and Configuration.md are updated.
• Symlinked package paths (553cdb8). Symlinks that stay inside the bundle are now accepted when the package itself lives under a symlinked path, such as /tmp → /private/tmp on macOS.

Fix: stale SwiftPM build manifest in the shared scratch path (875538a)

Direct executables build from the root package and wrapped products build from xtool/.xtool-tmp, all in one scratch path. SwiftPM's cached build manifest there does not track the package path or the --toolset. A build that ran after another package's build therefore reused the wrong manifest:

• A wrapped product failed with No target named '<Product>-arm64-apple-macosx15.0-debug.exe' in build description.
• A direct executable linked silently without its toolset options: no bundle rpaths, and minos/SDK left at the package minimum (11.0 instead of 15.0).

The previous head had this bug as well. Builds now pass --disable-build-manifest-caching. The native fixture test builds a direct XPC service after a wrapped extension; it fails without the flag and passes with it.

Build performance

• Ask SwiftPM for the build output directory once per package instead of once per product (cda0676).
• Build all wrapped products in one SwiftPM invocation (e799262).
• Parse Mach-O files from a memory-mapped buffer instead of copying every file, slice and archive member (3e694d5).
• Planning inspects at most one package per core at a time (d93f754).
• Planning reuses the describe/dump-package output of dependencies pinned to a released version. The cache lives in .build/xtool-inspection, keyed on toolchain, identity, URL, version, checkout path and traits. Local, branch and revision dependencies are inspected on every build (9683d82).

Measured on a synthetic app with 20 local package dependencies, two direct executables and three wrapped extensions. "Before" is the build fix alone, because the previous head could not build this fixture. The call counts are exact. The wall times are medians from a heavily loaded machine, so treat them as rough.

	swift build calls	median wall
clean	19 → 10	43.1 s → 33.5 s
no-op	13 → 6	12.7 s → 9.4 s

The inspection cache does not show up in that table, because all of the fixture's dependencies are local. On an app with two remote dependencies pinned to versions, a repeat build runs describe/dump-package for the root package only: 1+1 calls instead of 3+3.

Include the host platform in the inspection cache key.

If a checkout and its .build directory are used on both Linux and macOS, this key remains the same. A dependency manifest can use host-specific #if os(...) branches. inspect then returns the first host’s cached products, targets, or resources instead of inspecting the dependency for the current host. Add the host platform to the key. (github.com)
