Hey, try running run pod install in your terminal.

[framarini02]

Already done

[vitaliy-paliy]

Did it fix your issue?

[framarini02]

No

[vitaliy-paliy]

What version of Xcode do you have? Check out this StackOverflow question -- https://stackoverflow.com/questions/52077002/header-file-firebasecore-firebasecore-h-not-found-despite-importing-firebase

[framarini02]

Xcode 12

[vitaliy-paliy]

Oh, I see, do you use mChat.xcodeproj to run the app? You have to use the mChat.xcworkspace instead.

[framarini02]

i run mChat.xcodeproj

[vitaliy-paliy]

Yep, that is why some files are missing. You have to use mChat.xcworkspace in order for this app to work. More information here about the difference between the two ---> https://stackoverflow.com/questions/21631313/xcode-project-vs-xcode-workspace-differences

[framarini02]

so I have to start the file .xcworkspace first and press on run and then I have to use the other file .xcodeproj to start the app, right?

[vitaliy-paliy]

No, you now have to work only with mChat.xcworkspace. mChat.xcodeproj file does not support CocoaPods, that is why some files were missing.

[framarini02]

ok. now I try

[framarini02]

one last thing. Why does the program always give me an error when trying to archive? The error comes from lottoe-ios and says Undefined symbol: type metadata for Swift._StringObject.Variant

[vitaliy-paliy]

It might be a problem with Xcode 12 since it is still in beta. I would suggest using the one that is in the App Store right now. I think it is Xcode 11.5
airbnb/lottie-ios#1214

[framarini02]

I noticed one thing using the app. But aren't notifications supported?

[vitaliy-paliy]

Correct, this app does not support notifications.

[framarini02]

will you add them?

[vitaliy-paliy]

I'm not sure yet.
If you have any additional questions, email me. I'm closing this issue since the initial problem was resolved.
