AI BriefingiOS Developer Mode Built into a Hybrid App
Key point
An Oliveyoung iOS engineer introduces a custom developer mode built with SwiftUI to improve debugging efficiency in a hybrid app environment.
Details
The Oliveyoung app has a hybrid app structure in which many services run on a WebView basis. To resolve the frequent debugging requests between FE (Front-end) and iOS developers caused by this, as well as the hassle of two-way debugging, a dedicated developer mode was built.
The developer mode was quickly implemented using SwiftUI, and can be accessed via a floating button while the app is running. Its main features are as follows.
- WebView Debugger: Provides URL and User Agent modification, exploration of web logs (WKScriptMessage, JS execution logs), inspection of web storage (Session/Local Storage, Cookie), and runtime script execution.
- Stack Screen Log: Visualizes the app's view hierarchy and groups and manages logs by screen.
- Local Flag: Allows feature flags to be toggled On/Off directly within the app without changing server settings, reducing inefficiencies in the QA and development process.
By introducing these tools, debugging productivity was improved and communication costs with FE developers were dramatically reduced.
