This gist demonstrates how to build a Kotlin MPP library so that the iOS sourceSet depends on and uses an iOS Framework as a dependency.

Key ideas:

• We use [Carthage] to retrieve/build the iOS Framework.
• We use [cinterop] to create bindings allowing us to use the iOS Framework from Kotlin
• We build and publish the library using ./gradlew publishToMavenLocal
• We build and publish [klib] artifacts for both the arm64 and x86_64 architectures, you can easily add arm32 if you need.
• Note that the publish process also publishes a cinterop klib artifact, allowing dependents to also know about the iOS Framework headers.

You can find a gist explaining how to use such library in an iOS app [here][ios-app].

/**
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits
 *    but "incrementing" them by 1 (only in the case of a timestamp collision).
