About this converter
This free tool converts Prisma Schema into Swift struct. Prisma ORM schema model definition. Swift Codable struct. The conversion runs entirely client-side: nothing is uploaded, nothing is logged. Useful when you want to skip writing types by hand for an API response, a database row, or a config payload.
Why convert Prisma Schema to Swift struct
- • Generate Codable structs that decode JSON in one line.
- • Skip the manual init(from:) ceremony for routine API shapes.
- • Keep iOS networking code small and fully typed.
How to use
- Paste your Prisma Schema on the left panel, or pick one of the sample tabs above.
- The converter infers field names, optionality, and types automatically.
- Copy the generated Swift struct on the right and drop it straight into your codebase.
Common pitfalls
- • Inferred types only see the payload you pasted. Add nullable / optional flags for fields that can be missing.
- • Numeric types are inferred as integer or float based on the sample. Real APIs sometimes return both — widen to a number/float type when in doubt.
- • Empty arrays default to an `unknown` element type. Paste a non-empty sample to get a meaningful element type.
FAQ
Is this prisma schema to swift struct converter free?
Yes. It is fully free, no signup, and runs entirely in your browser. We do not store your input.
Does it work with nested objects and arrays?
Yes. Nested objects produce separate named types, and arrays infer the element type from the first non-null sample.
What about optional / nullable fields?
Fields whose value is null in the sample (or marked optional in JSON Schema / Prisma / GraphQL) are marked optional/nullable in the output. For real APIs, you may want to widen optionality manually after generation.
Can I generate Swift Struct from multiple Prisma Schema samples?
Today the tool processes a single sample. For more aggressive inference across multiple shapes, run the converter on the union/merge of your samples or open an issue.
Is the source code available?
Yes — the entire project is open source. See the GitHub link in the footer.
