1. Take the steps described in Integrate DevMateKit if you haven't done it yet.
  2. Add the following code snippet to the applicationDidFinishLaunching method of your application delegate class:
[DevMateKit setupIssuesController:nil reportingUnhandledIssues:YES];
DevMateKit.setupIssuesController(nil, reportingUnhandledIssues: true)
  1. Build and run your application.

To test issue the reporting functionality, run the following command in the terminal:

<executable> [-test_crash [delay_sec]] [-test_exception [delay_sec]]


  • <executable> is a path to the main executable of your app (e.g., <my_app_path>/MyApp.app/Contents/MacOS/MyApp). You can drag and drop your application from Xcode to Terminal and add MyApp.app/Contents/MacOS/MyApp.
  • test_crash is an argument to initiate crash.
  • test_exception is an argument to initiate exception.
  • delay_sec is time in seconds before an issue dialogue appear (don't specify to open an issue dialogue immediately).

To learn more, see an example on GitHub.


You can automatically fill in 'Name' and 'Email' fields of an issue reporting dialog with the values specified by a user during activation. Also, you can add some predefined text to the problem description field.

@property (nonatomic, retain) NSDictionary *defaultUserInfo;
FOUNDATION_EXPORT NSString *const DMIssuesDefaultUserNameKey; // NSString
FOUNDATION_EXPORT NSString *const DMIssuesDefaultUserEmailKey; // NSString
FOUNDATION_EXPORT NSString *const DMIssuesDefaultCommentKey; // NSString

To send a custom app log in an issue report to DevMate, specify URL to this log file(s).

@property (nonatomic, retain) NSArray *logURLs;

To track the relaunch of an application after crash, pass an object that implements the reporterWillRestartApplication method as delegate for the issue controller.

@protocol DMIssuesControllerDelegate <NSObject>
- (void)reporterWillRestartApplication:(DMIssuesController *)controller;

To customize the UI, you need to subclass DMIssuesWindowController class and set it to the main controller using the -[DMIssuesController setIssuesWindowControllerClass:] method.



To ensure correct work of the issue reporter, implement DMIssuesWindowController subclass and all other resources/classes in a separate framework.
