3

After having converted my project to swift 3 I get the following error when I post a simple message (log) from JS though the userContentController

contentController.add(self, name: "log")

func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage){
    return
}

window.webkit.messageHandlers.log.postMessage(args)

Sample(961,0x1b8f6dc40) malloc: *** error for object 0x1740b38c0:
pointer being freed was not allocated

I run my application on an iPhone 6/10.2. No error with the simulator.

I was able to reproduce this error with another application I downloaded from the web

It seems that's a bug of the framework (JSContext deallocation).

Any idea ?

Bug reported to Apple (29898945)

See below the stack (image).

Thank you so much

    To avoid this issue I've to uncheck "Automatically Show Web Inspector for JSContexts" in safari or to close Safari when I run my application – Frédéric Dal Bo Jan 06 '17 at 16:48
