👋 Hello

First off, many thanks for introducing opentelemetry-swift-core 💜 — it makes the Swift API much easier to adopt for SDK vendors 🚀.

That said, the current platform requirements in opentelemetry-swift-core are higher than Xcode’s actual minimum deployment targets, which limits adoption for SDK vendors like Datadog who aim to support a broader range of platforms. We would be happy to contribute a change to align these requirements.

Context

Since April 24, 2025, all apps uploaded to App Store Connect must be built with Xcode 16+ (source). To maximize compatibility, it makes sense to align with the deployment targets available in Xcode 16, as listed in Apple’s Xcode Releases matrix.

Although the matrix now lists iOS/tvOS 15, it was subject to ambiguity earlier this year when it originally listed iOS/tvOS 12. This update was later confirmed on Apple’s forum, clarifying that iOS 12 remains a valid — though discouraged — option.

In our view, SDKs should remain flexible and allow app developers to choose their own deployment baselines. Therefore, iOS/tvOS 12 should continue to be supported in by OTel Swift Api until Apple explicitly lifts this option (when requiring Xcode 26 for ASC uploads).

Proposal

The code changes required for this seem to be minimal, and we would be happy to contribute.

Would you be open to us opening a PR to propose this change?
