The SDK would incorporate this attribute into the variation bucket assignment hash. In previous versions of the SDK, you could set the value of a user's secondary attribute, as an optional secondary key for a user. To learn more, read Targeting with flags. For example, you can use /address/city in your targeting. In your flag or segment targeting, use / as the delimiter to refer to specific object fields.

Here's how to construct a basic context, as compared with constructing a user: Where you previously created users, now you must create contexts. Understanding differences between users and contexts To learn more about upgrading to contexts, read Best practices for upgrading users to contexts. Changes to alias events: The alias method has been removed.Changes to anonymous users: Client-side SDKs no longer automatically populate the device ID.Changes to automatic attribute population: The SDK no longer automatically populates the 'device' and 'os' properties.Changes to private attributes: You can mark specific attributes of a context as private, either across all contexts of any kind, or within a particular context or context kind.A flag's targeting rules can now address fields within a JSON object. You can still add as many custom attributes as you like, although the format has changed slightly. Changes to attributes: There are now fewer built-in attributes.Create contexts, not users: Where you previously created users, now you must create contexts.The primary differences between working with users and working with contexts include the following:

You must upgrade your SDK if you are going to use context kinds other than user in your flag configurations. If a flag configuration specifies any context kinds other than user, older versions of the iOS SDK will not evaluate the flag correctly. When older versions of the SDK send events to LaunchDarkly, LaunchDarkly will convert the users in those events to contexts with a kind of user. LaunchDarkly assumes older versions of the SDK use user contextsĪ context always has a kind attribute. If there are any instances you do not replace, the 8.0 version of the iOS SDK will convert each LDUser parameter it receives to LDContext and call the LDContext-specific version of the method. When you migrate from version 6.x or 7.x, replace every instance of a user with a context. The 8.0 version of this SDK lets you use contexts. To learn more about contexts, read Contexts. This new version of the LaunchDarkly SDK requires you to evaluate feature flags using an evaluation context, which is an object containing one or more contexts.

the device, model, and operating system of an environment, as part of a context with kind of 'device'.the company, department, and location of an organization, as part of a context with kind of 'organization'.the username, first name, last name, and email address of a person, as part of a context with kind of 'user'.When you evaluate a feature flag within your application, the flag's targeting rules use information from one or more kinds of contexts. Attributes can be strings, booleans, numbers, arrays, or JSON objects. Now you can define this information in a more structured way, using contexts.Įach context has a required attribute called kind that you can use to categorize context instances for targeting and Experimentation. In previous versions of the LaunchDarkly SDK, you could define this information in a user object, using a combination of built-in and custom attributes. Many LaunchDarkly customers create targeting rules for feature flags based on a variety of different information, including attributes pertaining to users, organizations, devices, and more. To learn more about updating to the latest 7.x version, visit the SDK's GitHub repository.

You can update them at your own pace while still using 6.x or 7.x, rather than migrating everything simultaneously.

If you update to the 6.x or 7.x version, deprecation warnings appear in areas of your code that need to be changed for 8.0. Functionally 7.x is exactly like 6.x except for minimum supported platforms. We released version 7.0 of the SDK when Apple released Xcode 14, which dropped support for some older OS targets. You do not need to upgrade to the 7.x version of the SDK before upgrading to 8.0. To upgrade to the latest Relay Proxy version, visit Relay Proxy releases on GitHub. To learn more, read the Relay Proxy 7.0 release notes. Additionally, if you use the Relay Proxy, you must update your Relay Proxy to version 7.0 before you update your SDK to version 8.0. Version 8.0 includes several breaking changes.

This topic explains the changes in the iOS SDK 8.0 release and how to adapt Objective-C code that currently uses a 6.x or 7.x version of the iOS client-side SDK to use version 8.0 or later. Read time: 10 minutes Last edited: Overview
