Is this an official TypeSafe SDK for Swift?

No. It is an independent project that implements the System One HTTP API, and it states plainly that it is not affiliated with or endorsed by TypeSafe AI.

Can I ship my API key inside a distributed Apple app?

Do not. The quick start belongs in a server or trusted CLI; send the credential in a Bearer header from your backend instead of shipping it in the app.

What happens when one answer in a batch is missing?

The client checks every requested answer before returning the batch, so missing answers, mismatched types, and bad option mappings throw errors instead of partial results.

How should I turn Noul and confidence values into actions?

A Noul near 0.5 is uncertainty, not medium intensity, and confidence summarizes a distribution without guaranteeing correctness. Set thresholds in app code and test them on your data.

What platforms and Swift version does JevSwiftSDK support?

Swift 6.0 or newer with Swift 6 concurrency checking, on iOS 15+, macOS 12+, or Linux with FoundationNetworking. It is dependency-free and sends the credential in the Authorization Bearer header.

What are the option and level limits for JevSwiftSDK questions?

Choice supports 1 to 255 options and Score supports 2 to 10 ordered levels, following the documented limits. Noul returns only a probability of yes with no separate confidence, and a score's fraction is measured on zero-based level indices.

How do I configure retries and a timeout?

JevConfiguration takes a model, a timeout and a retryPolicy, for example timeout 10 and RetryPolicy(maxRetries: 2). jev-latest follows service updates, so pin a version when reproducibility matters.
