This release is focused on compatibility, so the SDK integrates cleanly into modern Swift 6.x codebases. It also sets Hedera up for future work that can take advantage of Swift 6\u2019s stronger concurrency model, including sendable annotations, actor isolation, and compiler checks that help surface race conditions at build time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Limited Support of Swift 5.x<\/h3>\n\n\n\n<p>As of v0.47.0, <strong>Swift 5.x is still compatible, however, with limited support<\/strong>.
