Build IOS xcode warnings

I am trying to build my Ionic app for IOS but I am having a few problems - so I started a new ‘blank’ project and in xcode it has 16 warnings - do these need to be fixed?

xcode warnings:

I think they have sth. to do with cordova - and as long they are only warnings and your app will sill build proberly. I see nothing to be worried about.

Thanks @user5555 I think you are correct - still have not submitted app to store yet - I just don’t like having warnings hanging around.

Feel free to open a PR to cordova-ios that replaces all these usages with their replacements :wink:

Yes but is it a cordova problem? or is it a cordova running within Ionic problem?

I’ve got like a lot of Xcode warnings, like a loooooot (> 80). My app is in store since something like a year, this was never a problem.

Ionic uses Cordova for everything native, iOS or Android. So as soon as you run a commadn with cordova in it and work with the results, it is always coming from Cordova.

In this case, the code for the iOS project Cordova is using uses some deprecated methods.

Thanks @Sujan12 I will raise a PR with Cordova as soon my broadband gets back to normal - it is currently running very slow making everything difficult.
