running features

Running Features

Features are resolved through variations of relevant experiences. When you run a feature, the SDK finds all experiences whose variations include a fullStackFeature change linked to that feature, evaluates targeting rules, buckets the visitor, and returns the resolved feature status and variable values. See the data model for the full resolution chain.

Run a Single Feature

Returns a single feature's status and variable values for the current visitor.

// Non-optional by contract: a miss or not-ready visitor yields a disabled Feature, never nil.
let feature = await context.runFeature("feature-key")
if feature.status == .enabled {
    // resolve variables…
}

Parameters:

Parameter	Type	Required	Description
featureKey	string	Yes	The feature's unique key
attributes	object	No	Bucketing attributes (see creating a user context for the full attributes reference), plus:
			typeCasting (boolean) -- auto-convert values to the variable's defined type (default: true)
			experienceKeys (string[]) -- limit evaluation to specific experiences only

Run All Features

Returns all features with their status and variable values for the current visitor.

let features = await context.runFeatures()
for feature in features where feature.status == .enabled {
    print("enabled:", feature.key)
}

Parameters:

Parameter	Type	Required	Description
attributes	object	No	Bucketing attributes (see creating a user context for the full attributes reference), plus typeCasting (boolean, default: true)

Returns: An array of BucketedFeature objects.

BucketedFeature Fields

Each resolved feature is returned as a BucketedFeature with the following fields:

Field	Type	Description
featureId	string	The feature ID
featureKey	string	The feature key
status	string / FeatureStatus	"enabled" or "disabled" (PHP uses the FeatureStatus enum)
variables	object / array	The feature variables with their resolved values

Complete Example

End-to-end flow: initialize the SDK, create a user context, run a feature, and check its status and variables.

import ConvertSwiftSDK

let sdk = ConvertSwiftSDK(configuration: ConvertConfiguration(sdkKey: "your-sdk-key"))
try await sdk.ready()

let context = sdk.createContext(visitorId: "user-unique-id")
let feature = await context.runFeature("feature-key")

if feature.status == .enabled {
    // Typed accessor — returns nil on key miss or type mismatch:
    let ctaColor = feature.variable("ctaColor", as: String.self) ?? "#0066ff"
}
