Crate bevy_ios_toolkit 

bevy_ios_toolkit — native iOS integrations for Bevy, as ordinary ECS resources and messages.

Each integration is a cargo feature and a module:

feature	module	what it bridges
storekit	store	StoreKit environment + in-app purchases (iOS only)
ads	ads	Google AdMob ads + UMP consent
att	att	App Tracking Transparency prompt
gamekit	gamekit	Game Center auth, leaderboards, achievements
review	review	StoreKit review prompt
platform	platform	haptics, safe-area insets, links, share sheet, thermal/low-power state, boot shield, audio session

No feature is on by default. Enable exactly what you ship — a module’s extern "C" block only exists when its feature is on, and the matching Swift shim must be in your Xcode target or iOS linking fails on undefined symbols.

bevy_ios_toolkit = { version = "0.4", features = ["ads", "att"] }

bevy_ios_toolkit = { version = "0.4", features = ["storekit"] }

The native contract

Shared across every native module:

• Every native entry point is @_cdecl C-ABI, called from Rust.
• Async, delegate-driven SDK work surfaces as polled state (or a drained event queue) read once per frame — never callbacks into Rust, because re-entrancy against winit’s event loop is not safe.
• Each Swift shim sits behind #if canImport(...) with linking stubs, so the staticlib links on any target.

Off iOS, integrations keep a fake only where a real cross-platform flow benefits from one. StoreKit purchases are platform-owned: store is iOS only and has no desktop backend.

Modules

ads

Google AdMob ads as Bevy resources + messages.

att

App Tracking Transparency (ATT) as Bevy resources + messages.

gamekit

Game Center (GameKit) as Bevy resources + messages: authentication, leaderboard score submission, and achievement reporting.

platform

Apple-platform integrations — thin wrappers over the Platform Swift shim (one .swift file per concern under Sources/Platform/), no-ops off iOS.

prelude

review

Ask for an App Store rating via SKStoreReviewController / AppStore.

store

StoreKit 2 in-app purchases as Bevy resources + messages.

Structs

IosPlugin

Installs every enabled iOS integration. Composition is feature-driven: a module only wires its systems when its feature is on.
