Xcode shows us that a SIGABRT was thrown inside main. In the editor pane, Xcode highlights that function in main.m. Xcode highlights main in thread #1 since uncaught exceptions вЂњbubble upвЂќ to that location in the application. On the left-hand side, the debug navigator displays the application threads. Next, click the iOS appвЂ™s button until the application throws the exception and the debugger comes up in Xcode. After the build completes, the application will start in the simulator. Make sure that you have Run selected on the left-hand side, and debug build enabled on the right. We want to be sure we run a debug build, so start by holding the option key and clicking the run icon on the upper left-hand side of Xcode. LetвЂ™s start with replicating the error in the simulator. So, you can debug your application on your development desktop.

You can install and run applications with a single click, and the environment has integrated support for the lldb debugger.

The simulator supports all current iOS platforms. Xcode provides iOS developers with an integrated environment for developing, testing, and debugging iOS applications. So, weвЂ™ll need to run the application in a debugger to find the exact location. Since weвЂ™re dealing with an uncaught exception, the backtrace only provides us with a rough idea of where the error is occurring somewhere in UIKit. Raygun also provides a backtrace for the error.

NSRangeException indicates that the code exceeded the bounds of a data structure, and the report suggests a subscript out of range is causing the crash. The class name and error message tell us a lot about the error. But in the event of any errors happening in deployed applications, the date and time can be advantageous. Since we forced the error now, we donвЂ™t need the date and time.

( BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions ДЇortunately, you integrated your application with Raygun Error Monitoring and Crash Reporting, so you can use the information to get an idea of where to look for the bug. After you check out the project, add your Raygun API (Application Programming Interface) key to didFinishLaunchingWithOptions in AppDelegate.m

WeвЂ™ll use a single view iOS application for this tutorial. So, letвЂ™s get started! Step 1: Sample project The source code for this project is available on Github. WeвЂ™ll be using the current version of Xcode at the time of this writing, which is version 10. This tutorial requires a macOS computer with Xcode installed.
