ionic 5 iOS app stuck on Splash Screen with no error logs

Question

I'm trying to build my ionic iOS mobile app which based on cordova-ios 6.1.0 and ios 13.6. My app gets stuck on the Splash screen and the following are the XCode logs. I'm stuck in this issue for days and still no luck. Does anyone have a solution for this?

Answer 1

Finally, after trying so many ways, I was able to solve the issue.

I have solved the issue by running the below commands to my project directory :

npm install

sudo gem install cocoapods

pod repo update

ionic cordova platform add ios@5.1.0

cordova plugin update cordova-plugin-ionic-webview@latest

then I add the following to my config.xml under ios platform

<feature name="CDVWKWebViewEngine">
<param name="ios-package" value="CDVWKWebViewEngine" />
</feature>
<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

do not add
<preference name="WKWebViewOnly" value="true" />

and again in project directory,

ionic cordova prepare ios

cordova build ios
