usewkwebview=yes not working

[jacobweber]

Bug Report

Problem

What is expected to happen?

Opening an in-app browser with usewkwebview=yes works, when cordova-plugin-wkwebview-engine is installed.

What does actually happen?

Fails with an error in the Xcode console. Works when usewkwebview=yes is removed.

Information

See below.

Command or Code

cordova create CordovaTest com.test.cordovatest CordovaTest
cd CordovaTest
cordova platform add ios@5.0.1
cordova plugin add https://github.com/apache/cordova-plugin-wkwebview-engine#master
cordova plugin add cordova-plugin-inappbrowser@3.1.0
cordova prepare

Open in Xcode, select development team, and run.

Inspect in Safari debugger, and run command below in console. No browser appears. Running a second time shows a different error:

We are experiencing exactly the same issue when using cordova-plugin-ionic-webview v2.5.2

Environment, Platform, Device
iOS 13.1.2, iPhone 6S

Cordova CLI 9.0.0
Xcode 11.0 (11A420a), Mac OS 10.14.6

Hello,
I'm experiencing the same issue. This was not happening when I was using the iOS 12 SDK (works with Xcode 10.x, doesn't work with Xcode 11)

[Stephane84]

Hello,
same here. I have an ionic3 app, and, the latest version of cordova-plugin-ionic-webview 4.1.2 and inAppBrowser 3.1.0. Build the app with Xcode11 and with the option usewkwebview, the opening of an inAppBrowser display it and close it instantanly. With Xcode 10, no pb

To reproduce :

ionic start (choose a name, a template, set yes to add cordova, and no pour ionic dev tool)
ionic cordova platform add ios@5.0.1
ionic cordova plugin add cordova-plugin-ionic-webview@4.1.2
ionic cordova plugin add cordova-plugin-inappbrowser@3.1.0
npm install @ionic-native/in-app-browser

In app.module.ts add "InAppBrowser" in the providers
In app.component.ts add InAppBrowser in the constructor, and the create to open the iab when device ready :

constructor(private iab: InAppBrowser) {
this.iab.create('https://www.google.fr/', "_blank", "usewkwebview=true");

Launch in an emulator with Xcode11, on ios13 terminal. It's ko
On ios12 terminal, it is ok.

With cordova-plugin-ionic-webview version in 2.5.2 or 3.1.2 (older last stable), it's the same.

Last thing, at the begining, i was using cordova-plugin-ionic-webview 1.2.1 and inappbrowser 2.0.2. Without the usewkwebview option, the result was the same, when build with xcode11, and testing on ios13 only, the inappbrowser opened and closed just after. That's why i upgraded those 2 plugins, and try to set usewkwebview, because of the Apple Warning mail when using code containing UiWebview.
With the latest versions, without usewkwebview=true, it works, but preparing the future with WkWebview because of a probably removal of uiWebView, i'd prefer to usewkwebview now...

I am having this problem as well, albeit possibly for a different reason. I am using Capacitor which already uses WKWebView and, for that reason, does not allow me to install cordova-plugin-webview or cordova-plugin-wkwebview-engine. That said, since others are having this issue, this may not be relevant.

Should be fixed by #534

[gelinger777]

can somebody hint what exactly should we put in config.xml and where so that we activate this feature in ios for ionic?
