# Mobile OS compatibility

NFC Wallet SDK for iOS supports multiple iOS versions.

Thales tests the compatibility of **each iOS update** with the **latest NFC Wallet SDK release**.

### Supported iOS versions by SDK release

Each NFC Wallet SDK release defines its supported iOS versions (for example, the minimum supported iOS version).

For the requirements that apply to latest SDK version see [Supported environment](/nfc-wallet-sdk-ios/get-started/configuration/1.-binary-integration.md).

### iOS versioning

Apple typically uses a `MAJOR.MINOR.PATCH` format (for example, `18.1.2`):

* **MAJOR**: Significant platform changes that can introduce breaking changes.
* **MINOR**: New features and improvements that are typically backward compatible.
* **PATCH**: Backward-compatible bug fixes and security updates.

{% hint style="info" %}
The exact version numbering is defined by Apple and can change.
{% endhint %}

Apple publishes beta iOS versions ahead of the public release so application developers can validate compatibility.

* The number of beta releases and their publication schedule depend on Apple’s strategy.
* The publication date of the public release can change based on feedback from beta releases.
