💡 Motivation and Context

posthog-ios 4.0 raises its minimum iOS to 15 (PostHog/posthog-ios#876). KMP can't adopt it while its own floor is 13, so this raises the floor first. The 4.0 upgrade later is then just a pin change in libs.versions.toml.

This is breaking for apps that target iOS 13 or 14: their builds will fail until they raise their deployment target. KMP is pre-1.0, so it ships as 0.7.0 (minor) and is marked breaking in the changelog.

Device impact is effectively zero. In a one-day sample of posthog-kmp iOS events, the lowest iOS version was 17.

💚 How did you test it?

• ./gradlew :posthog-kmp:iosSimulatorArm64Test passes.
• The generated SwiftPM linkage package now declares .iOS("15.0").

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

• Written with Claude Code (Opus 5.5).
• Checked for cleanup the new floor allows: the KMP iOS sources have no OS-version checks, so there's nothing to remove.
• Kotlin 2.4's default iosMinimumDeploymentTarget is already 15.0, but the explicit setting stays so that a future Kotlin upgrade can't silently raise the SDK's floor.
• Kept at 15 instead of higher, to match posthog-ios.
• Docs follow-up on posthog.com: drop the "If your app supports iOS 13 or 14" paragraph in contents/docs/libraries/kmp/index.mdx when this ships.

Review recommendation: approve. Producer configuration and generated linkage manifests consistently declare iOS 15, and Kotlin 2.4.20 serializes this setting into publication metadata. The breaking minor release fits the documented pre-1.0 policy. Coordinate the planned installation-docs update with publication; the future native 4.0 upgrade still needs its own compatibility review. No findings.

Static source review, official version-pinned Kotlin source, and existing CI only; no tests run locally. Human-driven, agent-assisted review.
