iOS build issues

mobile
1

Heyo,

we just built our app for Android, which is working smoothly. However, the iOS build just does not want to work.

Xcode can load the projekt properly, and it will even start the app. Then it asks for GPS permission (which is good). The problem arises when it is supposed to load the content of the app - it just stays white. Again, it works on Android so Im guessing this is an issue with the setup?

Here is the relevant excerpt from the system log

Having the exact same issue. Can’t seem to find a solution.

Could not signal service com.apple.Webkit.WebContent: 113: Could not find specified service.

3

+1 having same issue - am able to run the app with ‘meteor run ios-device’ but not if I build the app and try to run it.

4

I am having exactly this issue on iOS 10, on iOS 11 it seems to be fine however :frowning:

6

Same issue. Getting Using WKWebView and then shortly thereafter CDVPlugin class CDVUIInAppBrowser (pluginName: uiinappbrowser) does not exist.w

Typically I have seen this error when running on a WIFI network that doesn’t allow guests to see each other. One way around that is to use a service like ngrok or zero tier to proxy requests using a VPN.

You should be able to verify if this is the case by checking that URL it’s trying to retrieve from. You can use Safari iOS debugging to see it’s actually to connect to that URL (or even try it in Safari on iOS)

Thanks @hexsprite, I ended up finding that if I needed to clear the configs and app builds:

rm -rf .meteor/local/cordova-build    
meteor remove-platform ios                 
meteor add-platform ios

then building with meteor build ../output-example --mobile-settings settings.json --server https://example.com
