Does code_forge 10.8.0 actually run on iOS 14? (pubspec floor vs. runtime)

Hi @heckmon,

I'm integrating code_forge into a Flutter app (a network debugging tool) and I need to confirm the actual iOS version support, since the README / podspec aren't 100% explicit about it.

My setup

• code_forge: ^10.8.0 (current latest on pub.dev is 10.12.0; I'm on the older 10.8.x line)
• iOS deployment target of the host app: 13.0
• iOS podspec of code_forge itself: s.platform = :ios, '11.0' (good — iOS 11+)
• Test device: iPhone 11, iOS 14.4.1

Question

Does code_forge actually run on iOS 14 devices, or is there an unofficial floor at iOS 15 / 16? Specifically:

1. flutter_rust_bridge ^2.12.0 (a hard dep) — what's its real minimum iOS version? IIRC some recent FFI/Rust-bridge work pushed the floor up.
2. The Rust static lib built by cargokit — any iOS 14.x-specific issues (e.g. stdlib symbols, Metal/Impeller interaction, FFI dynamic-loader edge cases on older OSes)?
3. Is there a tested matrix somewhere (CI / README) of iOS version × code_forge version that I can look at?

Context for why I'm asking

I'm seeing a native crash on iOS 14.4.1 that I'm trying to localize. I haven't pinned it to code_forge yet — could equally be Flutter engine / Impeller. Before I bisect further, I want to know whether iOS 14 is even in your support window. If the practical answer is "iOS 15+ only, iOS 14 not tested", I'll just bump my IPHONEOS_DEPLOYMENT_TARGET to 15 for the next release and stop chasing it.

Thanks!

I don't have an IOS device to replicate the exact status. The IOS configuration files were created by the FRB plugin itself, so I don't know much about the technical side of IOS version issue.

If you can, please create a PR with proper changes that updates the package to newer IOS standards, like this PR, which fixed the new android gradle version crash:
