<summary>Iterable/swift-sdk (Iterable/swift-sdk)</summary>

###
[`v6.5.12`](https://redirect.github.com/Iterable/swift-sdk/blob/HEAD/CHANGELOG.md#6512)

[Compare
Source](https://redirect.github.com/Iterable/swift-sdk/compare/6.5.11...6.5.12)

- Made `IterableDataRegion` an `@objc` class for better Objective-C
compatibility.
- Improved robustness of the SDK by adding more internal initialization
checks before executing certain operations.
- Enhanced thread safety for embedded message data handling, leading to
increased stability.
- Improved `IterableEmbeddedView` by making `imgView` and
`cardImageView` optional, leading to more robust view handling,
particularly for `.card` and `.banner` types when images might not be
present.
- Minor refinements to authentication and token refresh logic for
increased stability.
