使用firebase swift3时出现异常

Question

I am doing such as this example in the link:

https://www.raywenderlich.com/139322/firebase-tutorial-getting-started-2

but I am getting this exception

Terminating app due to uncaught exception 'FIRAppNotConfigured', reason: 'Failed to get default FIRDatabase instance. Must call FIRApp.configure() before using FIRDatabase.

I downloaded the final project from the same page and getting the same exception even if I put GoogleService-Info.plist and enabled the keychain!

any help is appreciated

Answer 1

You need to call FirebaseApp.configure() in your AppDelegate didFinishLaunchingWithOptions method, the name of firebase app now is FirebaseApp instead of FIRApp the tutorial is outdated

and use this pod file content

project 'Grocr.xcodeproj'

# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'

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

  # Pods for Grocr
  pod 'Firebase/Core'
end

also you need delete the pod folder and perform a pod install --verbose
