Error "Command failed due to signal: Segmentation fault: 11"

[catmans1]

import Firebase
......
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FIRApp.configure()
}

When I add firebase into my project via cocoa pod, It occurs error " Command failed due to signal: Segmentation fault: 11"
Please help me.
Thank!

Can you turn on debug mode by adding the argument flag -FIRAnalyticsDebugEnabled (see http://goo.gl/Y0Yjwu) and give us the log and stack trace? Thanks

Thank.

I am having the same problem (Segmentation Fault:11). After upgrading Firebase in our project, I get a segmentation fault.

func updateRealtimeFoo(snap: FIRDataSnapshot) {

}

This method declaration is causing the problem.

[baolocdo]

I have not encountered this issue before. It is probably the Swift compiler crashes due to initial project setup. Would you mind clearing the module cache, cleaning the build folder, and uninstalling and reinstalling the Pods? There are a few solutions here that you can try.
Also, make sure that you have added -ObjC in your other linker flags in build settings and that you have added the required frameworks as mentioned in here.
Please let us know if it works.

I do have the same issue with FIRDataSnapshot. None of the solution suggested in the Baolocdo's comment link have helped.

Hi all - is anyone still seeing these issues with Xcode 8 and the updated samples?

[jeremybroutin]

Yep, just implemented a copy of the FCM demo app (https://github.com/firebase/quickstart-ios/tree/master/messaging) and am getting the segmentation fault error. This also occurred in my own project while trying to implement FCM.

The error is located in the AppDelegate: "While deserializing AppDelegate".
I tried moving the extensions (to handle the delegates methods) into the class itself, but no better luck.

I also have same error.

Same problem. I actually didn't add my own code to the project - I'm just following the FriendlyChat tutorial instructions from Google Codelabs....

Same here when adding the Messaging delegates via the extensions

Trying updating cocoapod to the latest version, that was my issue ;)

@jeremybroutin I updated to 1.0.1 and dit a pod update but it didn't solve the issue. Also tried the 8.1 xcode beta to no avail 😞

edit: turns out I had use_frameworks off.. thanks!

[1amageek]

Do you use the use_frameworks! ?
I was solved with this.

In the project that can not use the use_frameworks!, I used the static library.

Firebase Integrate without CocoaPods

target 'YOUR_APP' do
  # Comment this line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!
  pod 'Firebase'
  pod 'Firebase/Messaging'
  pod 'Firebase/Database'
  pod 'Firebase/Crash'
  pod 'Firebase/Auth'

  target 'YOUR_APP_Tests' do
    inherit! :search_paths
    # Pods for testing
  end 

  target 'YOUR_APP_UITests' do
    inherit! :search_paths
    # Pods for testing
  end 

end

Closing - I think this one is generally either use_frameworks! or old cocoapods, but there is a lot of stuff that seems to segfault the toolchain!
