Cannot run new iOS app since latest upgrade

@gdorbes

I'm also encountering the same issue. Could you please explain how you resolved it in detail?

[gdorbes]

The issue was that in my latest app version I requested device info during script loading, before deviceready event. For some timing reason it worked with my android device, but not with my iphone one. I fixed the issue just by moving my request after deviceready.

NodeJS 20, or any current LTS is sufficient.

A white screen generally means there was a JS error on launch. This often isn't reported in Xcode, but it will be reported in Safari Web Inspector.

I have a guide that details how to use the web inspector. Safari Web Inspector doesn't capture log events that occurred before it was attached, so once attached, use cmd + R with the inspector window focused, it will refresh/reload the webview. Any JS errors on launch occurring should be logged and it should give you more insight on the underlying issue.

@gdorbes I have the same Issue, could you please provide more detail how have you resolved this issue? I would really appreciate it.

[TejasSatpute077]

Hi @Jakub-Horacek , I encountered the exact same issue before, but I managed to resolve it. Could you provide more details about the error you're facing? That way, I can offer you some assistance

[TejasSatpute077]

@Jakub-Horacek in your package.json check required node version mentioned in
"engines": {
"node": ">=18.18.2 <19"
},

and check which version of node you are using on terminal

node -v

and also check cordova version

cordova --version

and

cordova platform ls

[Jakub-Horacek]

@TejasSatpute077 Okay, thank you a lot for your time.

I'm getting this in a WKWebView-based app (not Cordova, but in-house framework) on Catalyst. The app seems to work fine, but it does look worrying.

[gdorbes]

My bad: the issue was elsewhere

[arlo1990]

@gdorbes what was the issue and how did you resolve?

[Jakub-Horacek]

@TejasSatpute077 Yes, I can try to provide as many details as you need, however I am really newbie iOS developer, so I am not sure what details I need to provide you.

When I launch my app in the simulator, it is stuck on the Launch Screen and the rest of the application is not displayed. There are no errors in the XCode Log. Only the warning mentioned in my previous message.

My app is using Ionic, Cordova, Capacitor and React.

@Jakub-Horacek if possible, provide me a screenshot of the page

[Jakub-Horacek]

@TejasSatpute077 It is just a blank screen with app logo.

[TejasSatpute077]

@Jakub-Horacek in your config.xml file set AutoHideSplashScreen as true and clean and build project again

[Jakub-Horacek]

@TejasSatpute077 When I set the AutoHideSplashScreen to true, the result is same, but without the logo. 😕

[Jakub-Horacek]

@TejasSatpute077

There is no

"engines": {
        "node": ">=18.18.2 <19"
      }

in my package.json, however it is MANY times (thousands) in the package.lock.json and each time with different node value.
I am currently sing the v20.11.0 node version in my terminal.

I found in my package.json only this information about the cordova: "cordova-plugin-ionic": "5.5.3",
and I am using the 12.0.0 ([email protected]) in my terminal.

@Jakub-Horacek

I encountered the same problem you're facing and resolved it by starting fresh with a new setup. Before that, I tried various solutions for the white screen issue and warnings you're experiencing, but none worked. You might want to try a fresh setup, ensuring compatibility with your current Node.js version.

[Jakub-Horacek]

@TejasSatpute077 So I managed to successfully connect to the Safari inspector for the JSContent as @breautek mentioned in the message above.

And I have these errors and warnings in the inspector:

The App is still not working but now I have some more informations, thank you.
