💡 Motivation and Context

posthog-ios 4.0 (PostHog/posthog-ios#873) removes the deprecated PostHogConfig(apiKey:) / PostHogConfig(apiKey:host:) initializers. The iOS target was still building its native config through apiKey:host:, so it would stop compiling once the posthog-ios dependency moves to 4.x.

This swaps that one call to the equivalent init(projectToken:host:), which has existed since posthog-ios 3.56.0 (we pin 3.64.1). The old initializer just forwarded to this one, so behaviour is unchanged.

Not changed: posthog-kmp's own public PostHogConfig.apiKey parameter, the posthog-ios version, and every non-iOS target. I also checked the Apple source sets for the other APIs removed in 4.0 (native apiKey property, propertiesSanitizer, evaluationEnvironments, remoteConfig, getFeatureFlagPayload, replay debouncerDelay / maskPhotoLibraryImages) and found no other uses.

💚 How did you test it?

• ./gradlew :posthog-kmp:compileKotlinIosArm64 :posthog-kmp:iosSimulatorArm64Test passes
• ./gradlew detekt passes
• Built sample/iosApp through Xcode and ran it on an iOS Simulator only (iPhone 17). A physical iPhone was paired but locked, so no on-device run was done.
  • With temporary, uncommitted sample edits, the app called PostHog.setup with a dummy token and a host pointing at a local mock server, then captured one event and flushed.
  • The mock server received GET /array/<token>/config, POST /flags?v=2 and POST /batch, each carrying the configured token as api_key; the batch contained the captured event. SDK debug logs showed batch sent successfully.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

• Authored with Claude Code (Opus 5.5) as a follow-up to the posthog-ios v4 deprecated-API removal.
• No change intent: this is an internal call-site swap with no user-visible change, so it does not need a changelog entry or a release on its own.
• No new test: existing iOS tests cover setup, and the change is a one-to-one initializer swap.
