I gave swift-openapi-generator a try to interact with Apple’s own App Store Connect API. The result was… unconvincing.

1️⃣ Compile time of my CLI reached 19 minutes:

[671/671] Linking mobile-cli
Build complete! (1137.97s)

2️⃣ The size of the CLI was 348M.

3️⃣ The command I wrote crashed because the API returned values that were not included in the OpenAPI spec.

Not a great 1st experience. 💻
