# Exemplos do Amazon Bedrock usando o SDK para Swift
<a name="swift_1_bedrock_code_examples"></a>

Os exemplos de código a seguir mostram como realizar ações e implementar cenários comuns usando o AWS SDK para Swift com o Amazon Bedrock.

*Ações* são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar perfis de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados.

Cada exemplo inclui um link para o código-fonte completo, em que você pode encontrar instruções sobre como configurar e executar o código.
