iOS Error - "stringByEvaluatingJavaScriptFromString" Undefined #25

Closed peterkrieg closed 6 years ago

peterkrieg commented 6 years ago

Hello,

using tns-ios 3.4.1, on Mac OS I'm having the following error: JS ERROR TypeError: this.webView.ios.stringByEvaluatingJavaScriptFromString is not a function.

I created a repo of minimal code to quickly see this issue: https://github.com/peterkrieg/nativescript-webview-interface-test. You just have to clone the repo and run tns run ios to see the error.

Full error copied below:
