No such module 'FirebaseDatabase'

Question

I am developing iOS app with Swift 3 with Firebase database.

My Podfile:

target 'MyApp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp
  pod 'Firebase/Core'
  pod 'Firebase/Auth'
  pod 'Firebase/Database'
end

I run pod install, which installs the pods.

I created a class:

import Foundation
import FirebaseDatabase // Error: no such module 'FirebaseDatabase'

class MyDatabase {
    var ref: DatabaseReference!
    ...
}

But I get compiler error no such module 'FirebaseDatabase', why?

Solution 1

Just try this , Make sure to Update all pods and secondly we don't need to explicitly import FirebaseDatabase , Just write import Firebase and you are done

import Foundation
import Firebase

class myDatabase {
    var DbReference = DatabaseReference()
}

My podFile

pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'Firebase/Storage'
pod 'Firebase/Database'

Solution 2

Build the project.

The project needs to be built once for modules that come from CocoaPods to get installed into Xcode's ModuleCache (~/Library/Developer/Xcode/DerivedData/ModuleCache/) and be available for the editor's syntax checking.

Solution 3

As per previous comment please check the above whether you are using:

1. .xcworkspace or not
2. Check your target name
3. Uninstall all pod and update your pod repo and than re install Pod

I did everything you mentioned, I get use of unresolved identifier 'DatabaseReference'

[iOS Geek]

Did you Tried Clean (window+shift+k) and close project , Reopen and Build (window+b)

This is a necessary runtime step as well. But he got a buildtime error, so he needs to look elsewhere ;)
