# SDK Customizations with the Service Chat SDK for iOS

Once you’ve played around with some of the SDK features, use this section to learn how to customize the Service Chat SDK user interface so that it fits the look and feel of your app. This section also contains instructions for localizing strings in all supported languages.

**important:** The legacy chat product is scheduled for retirement on February 14, 2026, and is in maintenance mode until then. During this phase, you can continue to use chat, but we no longer recommend that you implement new chat channels. To avoid service interruptions to your customers, migrate to [Messaging for In-App and Web](https://help.salesforce.com/s/articleView?id=service.miaw_intro_landing.htm&type=5) before that date. Messaging offers many of the [chat features](https://help.salesforce.com/s/articleView?id=service.miaw_chat_vs_messaging.htm&type=5) that you love plus asynchronous conversations that can be picked back up at any time. Learn about chat retirement in [Help](https://help.salesforce.com/s/articleView?id=001790618&type=1).

Many UI customizations are handled with the [`SCAppearanceConfiguration`](https://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCAppearanceConfiguration.html) object. You can configure the colors, fonts, and images to your interface with an [`SCAppearanceConfiguration`](https://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCAppearanceConfiguration.html) instance. It contains the methods [`setColor`](https://developer.salesforce.com/docs/service/service-sdk-ios/guide/%3Chttps://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCAppearanceConfiguration.html#/c:objc(cs)SCAppearanceConfiguration(im)setColor:forName:>), [`setFontDescriptor`](https://developer.salesforce.com/docs/service/service-sdk-ios/guide/%3Chttps://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCAppearanceConfiguration.html#/c:objc(cs)SCAppearanceConfiguration(im)setFontDescriptor:fontFileName:forWeight:>), and [`setImage`](https://developer.salesforce.com/docs/service/service-sdk-ios/guide/%3Chttps://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCAppearanceConfiguration.html#/c:objc(cs)SCAppearanceConfiguration(im)setImage:compatibleWithTraitCollection:forName:>). To use this object, create an `SCAppearanceConfiguration` instance, specify values for each token you want to change, and store the instance in the [`appearanceConfiguration`](https://developer.salesforce.com/docs/service/service-sdk-ios/guide/%3Chttps://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCServiceCloud.html#/c:objc(cs)SCServiceCloud(py)appearanceConfiguration>) property of the [`ServiceCloud`](https://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCServiceCloud.html) [`sharedInstance`](https://developer.salesforce.com/docs/service/service-sdk-ios/guide/%3Chttps://forcedotcom.github.io/ServiceSDK-iOS/releases/api/234.1/Classes/SCServiceCloud.html#/c:objc(cs)SCServiceCloud(cm)sharedInstance>).

There are other ways to customize the interface. When using Service Cloud features, various action buttons are available to the user. You can control the visibility of these buttons and even create new action buttons. You can also customize the strings used in the UI for any of the supported languages. String customization is performed using a standard [localization mechanism](https://developer.apple.com/internationalization/) provided to Apple developers.
