# iOS SDK - Version history

> Release history of the Kleep iOS SDK

The latest version is **4.3.0**. The SDK is distributed as a Swift package: [https://github.com/KlipFit/kleep-spm](https://github.com/KlipFit/kleep-spm) (see [installation](/mobile/ios#installation)).

To update the SDK, in Xcode choose **File > Packages > Update to Latest Package Versions**. With the dependency rule **Up to Next Major Version**, Xcode picks up every 4.x version without any change to your project settings.

## 4.3.0 — 2026-10-12

**Enhancements:**

* Retailer theme: the size guide uses the retailer's font, colors and buttons configured by Kleep. No integration change.
* The size guide stays inside the safe area when presented full screen, including on top of another modal.
* The SDK hides the system navigation bar itself: you no longer need to set `navigationBar.isHidden`.
* Add to cart: the SDK logs what `onResult` receives, to help debug add-to-cart integrations.

## 4.2.8 — 2026-10-04

* Kleep enables retailer apps remotely: a new app can be enabled without a new SDK version.

## 4.2.7 — 2026-09-28

**Fixes:**

* Swift 6 and strict concurrency support: `Klipfit` is main-actor isolated, and `Klipfit.shared` no longer triggers the "not concurrency-safe" error.

## 4.2.5 — 2025-12-15

**Enhancements:**

* Texts and translations can be updated by Kleep without a new SDK version.

**Fixes:**

* `requestSize` always returns the size recommended by Kleep, whatever size the shopper selected in the size guide.

## 4.2.4 — 2025-11-27

* App validation accepts bundle ID prefixes, so all builds of a retailer app can be enabled at once.

## 4.2.3 — 2025-11-19

* Diagnostic logs for app validation.

## 4.2.2 — 2025-09-18

**Fixes:**

* Translation fixes on the size recommendation screen.

## 4.2.1 — 2025-07-24

* Spanish and Portuguese text updates.

## 4.2.0 — 2025-05-21

**Enhancements:**

* The UI is available in French, English, Spanish, Italian, Portuguese and Dutch, set with the `language` parameter (`KleepLanguageCode`).

## 4.1.1 — 2025-01-31

**Fixes:**

* Layout fix for the out-of-stock label.

## 4.1.0 — 2025-01-15

**Enhancements:**

* New optional `stocks` parameter: the recommendation takes the stock of each variant into account.

## 4.0.5 — 2025-01-07

* First version distributed as a binary XCFramework through the public Swift package.
* `KleepResult` conforms to `Equatable`.
* New font and minor UI updates.
