1.0.0

(break): The Swift SDK generator reads configuration from sdk-config.yml instead of generators.yml. Run fern sdk migrate to create sdk-config.yml from your existing configuration. 1.0.0 is also the minimum version for generating Swift SDK Config targets locally.

This release changes the generated SDK. See the Swift v1 migration guide for details and code updates:

  • Numeric enums are generated as enums.
  • Union types changed shape.
  • Inline anyOf objects become one struct.
  • Initializer argument order changed for some allOf types.
  • Object schemas with empty properties become dictionaries.
  • Binary properties are typed as Data.
  • Some type names changed.
  • Failed requests are retried three times by default.
