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 1.71.0 XCFramework for arm64 iOS devices and arm64/x86_64 iOS Simulator. Includes all headers, compiled-component inventories, CMake and pkg-config metadata.

Included compiled libraries

  • boost_chrono — Compiled date and time duration support.
  • boost_date_time — Compiled date/time and locale facets.
  • boost_filesystem — Portable filesystem operations.
  • boost_graph — Compiled Graph algorithms.
  • boost_locale — Localization backends available without optional ICU packaging.
  • boost_random — Compiled random_device implementation.
  • boost_regex — Regular-expression engine.
  • boost_system — Error-code support required by several compiled libraries.
  • boost_thread — Portable threading primitives.
  • boost_context — Architecture-specific fcontext implementation carried forward from the validated configuration.

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 1.71.0 was released on August 19, 2019. This package carries forward the
nine baseline compiled libraries plus Boost.Context, includes the complete
updated header tree, and uses C++17.

New in Boost 1.71.0

  • Variant2 adds a header-only, never-valueless variant implementation with
    strong exception guarantees. Alternative selection and visitation are
    smoke-tested.

Relevant updates

  • Boost.Context and header-only Boost.Coroutine2 retain their validated
    architecture configuration and runtime coverage. The complete Boost 1.71
    smoke suite passed on a physical arm64 iOS device; Simulator runtime
    confirmation remains pending.
  • Header-only Boost.Signals2 remains the supported slot-dispatch path after the
    upstream removal of legacy compiled Boost.Signals in 1.69.
  • Boost.Fiber and deprecated compiled Boost.Coroutine remain excluded until
    they receive dedicated device and Simulator runtime coverage.

See COMPONENTS.md for the complete compiled-library inventory. All Boost
headers are included even when a corresponding compiled library is omitted.

Automated release validation

  • Complete-addon archive layout and package metadata
  • arm64 device and arm64/x86_64 Simulator XCFramework slices
  • Standalone XCFramework and Swift package examples
  • iOS Simulator smoke suite
  • CocoaPods package metadata
