After years of shipping Bluetooth Low Energy applications, I kept hitting the same wall: the tools we use to talk to BLE devices — scan, connect, poke at characteristics, reproduce edge cases — are still stuck in the terminal-era. So I built Signal Hub, a Mac app for engineers who live in the BLE stack.

Signal Hub lets you manage concurrent BLE connections, design visual workflows that run on real hardware, simulate devices when the prototype hasn’t shipped yet, organize everything in workspaces, and export beautiful PNG / video documentation — all from one calm, elegant app.

As an iOS developer, you might have chances to write applications on Mac os. And sometimes, your applications require users to authenticate before they can use your app. Enabling Google Sign in helps you save a lot of time to implement authentication flow. Unfortunately, it is a lack of documentation on how to integrate Google Sign in on Macos app, particularly in Swift. I once had a chance to implement this feature to my app. Now I want to share with you how we can do it. Let’s get started.
