WKWebViewJavascriptBridge did not support Swift?

[kmyhy]

I used WebViewJavascriptBridge in my Xcode6.4 project(Swift),it is ok.
But when I tried to import WKWebViewJavascriptBridge in the same project,I got that compiler error:
Undefined symbols for architecture x86_64:
"OBJC_CLASS$_WKWebViewJavascriptBridge", referenced from:
__TMaCSo25WKWebViewJavascriptBridge in WKWebViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have the same issue. It works for UIWebView but WKWebView throws said error... :(

I'm seeing the same error on an Objective-C project in Xcode 7.0.1. I was using WebViewJavascriptBridge fine with UIWebView, but when I tried to switch to WKWebViewJavascriptBridge for WKWebView, I started seeing this linker error.

Same issue here. Is there a workaround?

@rexpie I needed to move on and was able to drop iOS 7 support, so I personally switched to just using WKScriptMessage/WKScriptMessageHandler.

@dwieringa Okay thanks for that.
Hey I just worked out a way to get this right.

In file WKWebViewJavascriptBridge.h, find these lines:

#if (__MAC_OS_X_VERSION_MAX_ALLOWED > __MAC_10_9 || __IPHONE_OS_VERSION_MAX_ALLOWED > __IPHONE_7_1)
#define supportsWKWebKit
#endif

Then remove the #if #endif pair, just leave the #define supportsWKWebKit bit out. But make sure you are using iphone 7.1 or above or it won't support WKWebkit.

Hey guys,

WKWebView is only available in iOS 8 and later (https://developer.apple.com/library/ios/documentation/WebKit/Reference/WKWebView_Ref/).

I believe the problem you're seeing is due to attempting to use WKWebViewJavascriptBridge.h in iOS 7 when you should be using WebViewJavascriptBridge.h.

Feel free to reopen if you think I got it wrong.

Cheers!
