1.0.0

First public release.

Tiny, dependency-free Swift package that tells you whether your app has been installed on this device before — even after it was deleted and reinstalled — by persisting an anonymous, self-generated identifier in the Keychain.

Highlights

• InstallIdentifier.shared.resolve() returns a stable id, firstSeenDate and isFirstLaunchEver
• Three accessibility modes:
  • .afterFirstUnlockThisDeviceOnly (default) — strictly device-local
  • .afterFirstUnlockMigratable — carries over when a backup is restored onto a new device
  • .afterFirstUnlockSynchronizable — additionally live-syncs via iCloud Keychain
• Injectable KeychainStoring protocol for deterministic unit tests
• Ships a PrivacyInfo.xcprivacy: no tracking, no collected data, no required-reason APIs
• SwiftUI example app in Example/ for verifying behavior on a simulator or device

Requirements

iOS 13+ / macOS 11+, Swift 5.9+
