featurevisor-example-ios

A small SwiftUI application showing how to use the Featurevisor Swift SDK.

The application downloads a Featurevisor datafile, creates an SDK instance, and evaluates the mobile_experience feature as a flag, variation, and string variable.

Requirements

You need Xcode 16 or newer. The application targets iOS 14 or newer.

Run the application

1. Open FeaturevisorExampleIOS.xcodeproj in Xcode.
2. Wait for Swift Package Manager to resolve the Featurevisor dependency.
3. Select an iPhone simulator.
4. Run the FeaturevisorExampleIOS scheme.

Featurevisor usage

The application fetches this production datafile:

https://featurevisor-example-cloudflare.pages.dev/production/featurevisor-mobile.json

The important SDK usage is in FeaturevisorViewModel.swift:

let datafile = try DatafileContent.fromData(data)
let f = createFeaturevisor(
    FeaturevisorOptions(datafile: datafile)
)

let context: Context = [
    "userId": .string("mobile-user"),
    "country": .string("nl")
]

let enabled = f.isEnabled("mobile_experience", context)
let variation = f.getVariation("mobile_experience", context)
let message = f.getVariableString(
    "mobile_experience",
    "welcome_message",
    context
)
