Crashlytics not reporting crash in Release mode

Crashlytics has been installed in the app in question for a couple of releases now. It's been working great.

But as we prepare the next release Crashlytics has stopped reporting crashes in Release mode. Here are the things I can think of that have changed since our last release.

  • Xcode 7.1. The last release was prepared with Xcode 6.

  • We upgraded to Fabric.

  • We're testing the app on iOS 9.1.

Anyway, with all those changes crashes are still being reported just fine in Debug. Just not in Release (installing from TestFlight after archiving and uploading to iTunes Connect).

Here are the things I've checked:

  • On the Fabric site the app is there, the version and build are there. When I click on Missing DSYMs it tells me there are none missing.

  • startWithAPIKey
    is being called in
    (added after trojanfoe's question).

  • The api key is correct. Checked and double-checked.

  • In the build script there isn't (and never was) a distinction between Debug and Release. It looks like this:

  • In Build Settings
    is already set to
    DWARF with dSYM File
    (added after StormXX's question):

What am I missing?

Mike from Crashlytics and Fabric here.

With Fabric, the initialization of Crashlytics did change slightly. Using the following code should work (Obj-C):

#import "AppDelegate.h"
#import <Fabric/Fabric.h>
#import <Crashlytics/Crashlytics.h>

@interface AppDelegate ()


@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    [Crashlytics startWithAPIKey:@"YourAPIKey"];
    // You can comment out the above line if you have your Twitter Fabric API key in your info.plist.
    [Fabric with:@[[Crashlytics class]]];
    return YES;

Updating the run script build phase to the following is also recommended:

./Fabric.framework/run <YourAPIKey> <YourBuildSecret>
