How do I send a message from JavaScript to the Swift host?

You can use the built-in utility window.__bridgeCore.sendToSwift('event_name', { data: 'payload' }) to trigger the bridge's onMessage handler or delegate.

Can I use WebViewBridge to debug JavaScript console logs in Swift?

Yes, by registering the core modules, console.log messages are automatically captured and sent to Swift as 'console_log' type messages.

Why does callJavaScript require a return statement in this framework?

The macOS WebPage.callJavaScript() API requires an explicit 'return' statement to pass values back to Swift. Without it, the call will return null even if the expression evaluates correctly.

Which macOS versions are supported by WebViewBridge?

WebViewBridge is designed for macOS 26.0 and later, utilizing the modern WebPage API for enhanced performance and security.

개발자 도구

Simplifies bidirectional communication and JavaScript injection for macOS WebPage components using the WebViewBridge framework.

소개

WebViewBridge Guide is a specialized resource for developers building macOS 26.0+ applications that require deep integration between native Swift code and web content. It streamlines the implementation of bidirectional communication, allowing for seamless JavaScript injection, message handling via delegates or closures, and sophisticated data exchange using the WebPage API. This skill is essential for bypassing common implementation hurdles, such as the specific return requirements for JavaScript execution, and provides standardized patterns for registering modules and intercepting network traffic.
