iOS Configuration Options

Method	Description	Default Values	Possible Values
deploymentEnvironment	The environment SDK connects to.	CardinalSessionEnvironmentProduction	CardinalSessionEnvironmentStaging CardinalSessionEnvironmentProduction
uiType	Interface types that the device supports for displaying specific challenge user interfaces within the SDK. This setting interacts with renderType in important ways. See renderType below for more information.	CardinalSessionUITypeBoth It is recommended that you use `CardinalSessionUITypeBoth` to ensure your SDK integration can accept and render both the Native and HTML render types an issuer may use. Deviating from this default value could result in impacts to overall SDK transaction performance.	`CardinalSessionUITypeBoth` `CardinalSessionUITypeNative` `CardinalSessionUITypeHTML`
renderType	List of all the RenderTypes that the device supports for displaying specific challenge user interfaces within the SDK. Note: When using `CardinalSessionUiTypeBOTH` or `CardinalSessionUiTypeHTML`, all renderType options must be set. When using `CardinalSessionUiTypeNative`, all renderType options except `CardinalSessionRenderTypeHTML` must be set. See uiType above for more information on which UiType to use.	`CardinalSessionRenderTypeOTP` `CardinalSessionRenderTypeHTML` `CardinalSessionRenderTypeOOB` `CardinalSessionRenderTypeSingleSelect` `CardinalSessionRenderTypeMultiSelect`	`CardinalSessionRenderTypeOTP` `CardinalSessionRenderTypeHTML` `CardinalSessionRenderTypeOOB` `CardinalSessionRenderTypeSingleSelect` `CardinalSessionRenderTypeMultiSelect`
proxyServerURL	Proxy server through which the Cardinal SDK Session operates.	nil	String Value
requestTimeout	Sets the maximum amount of time (in milliseconds) for all exchanges	8000	>=0 Milliseconds (Integer)
challengeTimeout	Challenge Screen Timeout in Minutes.	5	>=5 minutes (Integer)
uiCustomization	Set Custom UICustomization for SDK Controlled Challenge UI.
enableDFSync	Enable DF Sync to get onSetupCompleted (Step 4) called after collected Device Data is sent to the server.	true	Boolean
threeDSRequestorAppURL	Merchant app declaring their URL within the CReq message so that the Authentication app can call the Merchant app after OOB authentication has occurred. Each transaction would require a unique Transaction ID by using the SDK Transaction ID.		String Value
collectLogs	Enables collecting SDK logs	true	Boolean
enableQuickAuth (deprecated)	Enable Quick Authentication	false	Boolean
darkModeUiCustomization	Set Custom UICustomization for SDK Controlled Challenge UI.		-
