Amazon Cognito authenticate user with saml and get table data from DynamoDB. Swift -

i new amazon web services.

all tables stored in dynamodb. query how manage , authenticate user ?

for example.

suppose assume have username called mike , password testmike. when press login button using cognito (saml) autenticate user , if user return success message fetch table data user pool. how can achieve this? read amazon developer guide confused how implement in code.

or without saml possible ?

can provide sample code here ?

your appreciated .

if have own user directory supports saml idp can use saml federation , access dynamodb table cognito identity credentials.

if want create user signup , signin functionality , let cognito manage users, can use cognito user pools. user data not stored automatically in dynamodb. if want store additional data related user, can federate cognito user cognito identity , use these credentials write cognito sync or dyanamodb.
