Xcode 12: How to fix the error 'archiveRootObject:toFile:' is deprecated

I am using a beta of Xcode 12 (Version 12.0 beta (12A6159)). My project uses Firebase. When I try to build it, some errors appears, like this one :

'archiveRootObject:toFile:' is deprecated: first deprecated in iOS 12.0 - Use +archivedDataWithRootObject:requiringSecureCoding:error: and -writeToURL:options:error: instead

Xcode tells me to fix this problem in the folder "GoogleDataTransport", in a file at this line:

[NSKeyedArchiver archiveRootObject:self toFile:[GDTCORStorage archivePath]];

I tried to follow stupidly what the error message tells me to do, so I started to write what the error says. I taped:

[NSKeyedArchiver archivedDataWithRootObject:<#(nonnull id)#> requiringSecureCoding:<#(BOOL)#> error:<#(NSError *__autoreleasing  _Nullable * _Nullable)#>];

I have no idea what I'm supposed to write to complete the blanks. Would anyone have any idea?

Even if we update the Firebase SDK to the latest version, errors still appear (with Xcode 12 beta (12A6159)). I reported this issue to Firebase Support. They told me it looks like a problem with CocoaPods. However, they gave me a workaround.

I will update this post when I have more informations.
