Boost is a large, peer-reviewed collection of portable C++ libraries that both fills gaps in the standard library and serves as a proving ground for features—many of which (like smart pointers, regex, and filesystem) later get adopted into the C++ standard itself.
Precompiled Boost 1.89.0 XCFramework for arm64 iOS devices and arm64/x86_64 iOS Simulator. Includes all headers, compiled-component inventories, CMake and pkg-config metadata.
- Boost 1.89.0 upstream release page
- C++ language standard: C++20
- Minimum iOS version: 12.0
Included compiled libraries
boost_chrono— Compiled date and time duration support.boost_date_time— Compiled date/time library retained for build compatibility.boost_filesystem— Compiled Filesystem v4 support.boost_graph— Compiled Graph algorithms.boost_locale— Compiled localization backends without optional ICU packaging.boost_random— Compiled random_device implementation.boost_thread— Portable threading primitives.boost_context— Architecture-specific fcontext implementation.boost_nowide— Compiled UTF-8 adapters.boost_json— Compiled parser and DOM support.boost_serialization— Compiled archive support.boost_url— Compiled URL parser.boost_container— Compiled polymorphic memory resources.boost_log— Compiled logging core and setup support.boost_stacktrace— Compiled portable basic backend only.boost_timer— Compiled CPU timer.boost_type_erasure— Compiled dynamic binding support.boost_cobalt— Compiled C++20 coroutine library carried forward from Boost 1.84.boost_charconv— Compiled locale-independent numeric conversion library required by Boost.MySQL.
All Boost headers are included. Header-only facilities remain available even
when their related compiled library is not part of the combined static binary.
Release features and exclusions
Boost 1.89.0 was released on August 14, 2025. This package remains on C++20
with an iOS 12.0 deployment target.
New libraries
Boost.Bloom provides space-efficient probabilistic filters. Its headers are
packaged and receive deterministic insert/lookup coverage without adding a
static archive.
Packaged libraries
The Boost 1.88 compiled set carries forward except Boost.System, whose 1.89
Boost.Build target is now a header-only alias and emits no static archive.
Charconv, Cobalt, and the portable basic Stacktrace backend remain compiled.
Redis retains its separate-compilation consumer model. Process v2 remains
excluded pending dedicated iOS process-spawning validation.
Validation scope
The complete earlier regression suite is retained. Release-specific coverage
includes Boost.Bloom. Three-slice packaging, standalone, SwiftPM, and local
CocoaPods consumers pass. The complete runtime suite passes on an arm64 iOS
Simulator and physical arm64 iOS device.
Device and Simulator validation

Only checks observed locally, reported by the maintainer, or proven in CI are
recorded as passed.
