Hello,
Okta does not provide SDKs for SAML Applications.
With OIDC applications and Native Mobile apps the intention is for the Mobile application to authenticate and then receive tokens from Okta and use those tokens within the Native App to establish a session.
SAML Apps rely on a SAML Trust with a server app and IdP. You wouldn’t (or shouldn’t) send a SAML Response to a Native Application to consume, therefore no SDK. Is your clients SAML application a server side application that you would like to protect with Okta SAML and be able to access it with a mobile device?
Thank You,
