Xcode Warnings

Hi,
Are you sure those warnings are related to I2 Localization? What they are saying is that some libraries are being compiled with a different "Symbols Hidden by Default" value.

I tried deploying an empty I2 Localization with the latest xcode and I'm not getting any warning.

Can you please, try removing I2 Localization and seeing if you still get warnings. If you don't get them again, did the warnings started showing after updating unity as well? It could be that the latest il2cpp is deploying some libraries with the wrong visibility.

Also is there a way to disable auto translation so that my app won't cause an error when there is no internet available.

Your app shouldn't cause an error where there is no internet. Is that happening?

What should be happening is that when you have Google Live Synchronization enabled, the app will try contacting the spreadsheet, if there is no internet, then it will fail, print a log to let you know what happened, and revert to using the localization data you had when you deployed or the last one that was downloaded.

So, you will only get a message in the log, but no crashes, hard warnings or any other issue for your app.

If you get anything else than a line in the log saying it was unable to download the data, please, let me know, that will certainly be a bug!

EDIT: You can also disable Google Live Synchronization by opening the I2Languages.prefab and in the Spreadsheet tab, select NEVER as the update frequency.

Hope that helps,
Frank
