FIRApp Linker Error [“_OBJC_CLASS_$_FIRApp”]

i0S Swift Issue

Question or problem in the Swift programming language:

I have scoured SO and Google but can’t find an answer that works. I have used the new Firebase Cocoapod on multiple projects but now, when adding it to a different project I am getting the following error.

I am using Xcode 7.3.1 with cocoapods 1.0.1.

Here is my podfile:

Any help is greatly appreciated!

How to solve the problem:

Solution 1:

Go to Build Settings > Other Linker Flags > on a new line $(inherited).

Do a Cmd+Ctrl+K for a clean, and then build.

Solution 2:

Uncomment this line to define a global platform for your project

platform :ios, ‘9.0’

target ‘AppName’ do # Comment this line if you’re not using Swift and don’t want to use dynamic frameworks inhibit_all_warnings! use_frameworks!

Pods for FCM

pod ‘Firebase’ pod ‘Firebase/Core’ pod ‘Firebase/Messaging’


Hope this helps!
