how to get bearer token from firebase on ios in swift

To get a firebase auth bearer token on iOS with Swift, you can use FirebaseAuth framework to sign in with user's credentials to get the token. Here is an example:

First, import FirebaseAuth:


main.swift
import FirebaseAuth

2 lines

Then, sign in with user's credentials:


main.swift
Auth.auth().signIn(withEmail: email, password: password) { [weak self] authResult, error in
    // check if there's an error
    guard let StrongSelf = self else {
        return
    }
    
    if let error = error {
        // handle the error
        print(error.localizedDescription)
        return
    }
    
    // get the token for current user
    authResult?.user.getIDToken(completion: { (idToken, error) in
        if let error = error {
            // handle the error
            print(error.localizedDescription)
            return
        }
        
        print("Id Token: \(idToken)")
    })
}

In the above code snippet, we first sign in the user with the email and password. After successful authentication, we get the token associated with the user using getIDToken(completion:) function.

Note: This token can be used to authenticate Firebase Services by providing it in the Authorization header of the request.
