Serverless Swift APIs with Apache OpenWhisk
summary
Shows how to deploy compiled Swift functions to Apache OpenWhisk / IBM Cloud Functions using the bx wsk CLI, turning a local Swift 4 Codable handler into a web action or API-gateway endpoint. Demonstrates a working Bitcoin conversion service that calls CoinDesk over HTTP, scales to thousands of concurrent invocations, and avoids long-running servers; notes cold-starts with source builds, recommends deploying binaries, cites 5–10 minute timeouts and ~GB memory limits and claimed cost savings up to 95%.
