We are now working on the brand-new Swift SDK for iOS. While it’s still in the early stages and has limited features, we are actively developing it to provide users with a truly exceptional experience.

​
Install SDK

Qonversion supports Cocoapods and Swift Package Manager to package your dependencies as a framework.

​
Install via Cocoapods

Add dependency to Podfile.
Podfile
pod 'Qonversion'
Run pod install in the project directory to download the dependency.
Terminal
pod install

​
Install via Apple Swift Package Manager

Open Xcode, go to File → App packages… and enter the package URL https://github.com/qonversion/qonversion-ios-sdk to the search bar to import the package.

​
Initialize SDK

For now, Qonversion Swift SDK supports only analytics launch mode. 
import Qonversion

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    let config = Qonversion.Configuration(apiKey: "api_key", launchMode: .analytics)
    Qonversion.initialize(with: config)
    return true
}
Once initialized Qonversion SDK can be accessed via the Qonversion.shared property. You can also use the instance returned by the Qonversion.initialize method.

​
Apple Search Ads Attribution

Qonversion Swift SDK allows collecting Apple Search Ads attribution data. To enable it simply call the following SDK method. Also don’t forget to complete the rest steps from this page. 
Qonversion.shared.collectAppleSearchAdsAttribution()

​
User Properties

​
Set User Properties

Via Qonversion Swift SDK you can set both Qonversion-defined and custom user properties as follows. 
// Setting Qonversion-defined user property
Qonversion.shared.setUserProperty("me@qonversion.io", key: .email)

// Setting custom user property
Qonversion.shared.setCustomUserProperty("yes", key: "liked-app")

​
Get User Properties

You can also request all the user properties set for the current user using the following method. 
let userProperties: Qonversion.UserProperties = try await Qonversion.shared.userProperties()
userProperties.properties.forEach({ userProperty in
    print("User property: ", "key: ", userProperty.key, ", value: ", userProperty.value)
})
The object returned by the userProperties method contains several utility fields and methods: 
let userProperties: Qonversion.UserProperties = try await Qonversion.shared.userProperties()

// List of all user properties
let allProperties: [UserProperty] = userProperties.properties

// Subset of all user properties, which were set using Qonversion-defined keys                                  
let definedProperties: [UserProperty] = userProperties.definedProperties

// Subset of all user properties, which were set using custom keys
let customProperties: [UserProperty] = userProperties.customProperties

// A flattened version of all user properties as a key-value map
let flatPropertiesMap: [String: String] = userProperties.flatPropertiesMap

// A flattened version of defined user properties as a key-value map
let flatDefinedPropertiesMap: [UserPropertyKey: String] = userProperties.flatDefinedPropertiesMap

// A flattened version of custom user properties as a key-value map
let flatCustomPropertiesMap: [String: String] = userProperties.flatCustomPropertiesMap

// Searches for a property with the given property key in all properties list
let customProperty: UserProperty? = userProperties.property(for: "customKey")

// Searches for a property with the given Qonversion-defined property key in the defined properties list.
let emailProperty: UserProperty? = userProperties.definedProperty(for: .email)

[[Qonversion sharedInstance] userProperties:^(QONUserProperties * _Nullable userProperties, NSError * _Nullable error) {
  ...
  // List of all user properties
  NSMutableArray<QONUserProperty *> *allProperties = userProperties.properties;
  
  // Subset of all user properties, which were set using Qonversion-defined keys
  NSMutableArray<QONUserProperty *> *definedProperties = userProperties.definedProperties;
  
  // Subset of all user properties, which were set using custom keys
  NSMutableArray<QONUserProperty *> *customProperties = userProperties.customProperties;
  
  // A flattened version of all user properties as a key-value map
  NSMutableDictionary<NSString *, NSString *> *flatPropertiesMap = userProperties.flatPropertiesMap;
  
  // A flattened version of defined user properties as a key-value map
  NSMutableDictionary<NSNumber *, NSString *> *flatDefinedPropertiesMap = userProperties.flatDefinedPropertiesMap;
  
  // A flattened version of custom user properties as a key-value map
  NSMutableDictionary<NSString *, NSString *> *flatCustomPropertiesMap = userProperties.flatCustomPropertiesMap;
  
  // Searches for a property with the given property key in all properties list
  QONUserProperty *customProperty = [userProperties propertyForKey:@"customKey"];
  
  // Searches for a property with the given Qonversion-defined property key in the defined properties list.
  QONUserProperty *emailProperty = [userProperties definedPropertyForKey:QONUserPropertyKeyEmail];
}];

(Optional) Set IDFA (Identifier for Advertisers, iOS 14.5+ only)

Qonversion can also collect Advertising identifier if you receive the app tracking permission using ATT. 
ATTrackingManager.requestTrackingAuthorization { status in
    switch status {
    case .authorized:
        Qonversion.shared.collectAdvertisingId()

    // handle other states below
    }
}
