I recently updated my Mac system from macOS 10.12.6 with Xcode 9.2 and iOS SDK 11.2 to macOS 10.13.6 with XCode 10.1 and iOS SDK 12.1 (cannot update to a more recent macOS right now).
My Ionic app was using UIWebView. Keyboard stopped working. When I restored the older macOS and rebuild Cordova, it worked again. But we all know UIWebView is deprecated so I started to migrate to WKWebView built against the newer iOS SDK. Keyboard still does not work. I tried and checked the following:
- Put
NSAllowsArbitraryLoadsinInfo.plist
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
-
Adding
cordova-plugin-wkwebviewxhrfixfrom https://github.com/TheMattRay/cordova-plugin-wkwebviewxhrfix -
Editing the Cordova library source code, to replace the call to
loadFileUrlmethod with loadRequest even for file:// URLs, as hinted at https://github.com/syrjs/core/blob/develop/ios/SyrNative/SyrNative/SyrBridge.m . It did not work, so I reverted the source.
Currently, with WKWebView, my start page is displayed in the simulator, but the virtual keyboard is not presented when I focus on a Text Box.
The following error messages are printed in iOS Simulator console:
Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service
Could not signal service com.apple.WebKit.Networking: 113: Could not find specified service
I added several log messages to Cordova to help diagnosing the problem.
Here are the messages I have :
