LastCrash iOS Sample Application

SDK Setup Instructions

Add LastCrash to your project:

• Copy LastCrash.xcframework from this repository into your project
• Make sure it's included under Targets > YOUR TARGET > General > Frameworks, Libraries, and Embedded Content

Initialize SDK:

• Replace LASTCRASH_API_KEY with your LastCrash API key.

Optional Delegate

Setting the delegate is optional. If you would like to control the logic behind sending crash reports then implement the LastCrashDelegate interface and call setDelegate.

The lastCrashDidCrash method will be called when crash reports are available to send. This allows you to implement your own logic or ask the user for permission to send crash reports.

LastCrash.send() must be called to send the crash reports if the delegate is used.

Application not responding support

A call to LastCrash.applicationInitialized() must be made after your app is initialized in order to track application not responding (ANR) errors.

The reason this call to LastCrash.applicationInitialized() is required is to starting ANR monitoring only after everything in your app is initialized/loaded so false positives can be avoided.

Swift:

import LastCrash
...
class AppDelegate: UIResponder, UIApplicationDelegate, LastCrashDelegate {

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    ...
    LastCrash.configure("LASTCRASH_API_KEY")
    LastCrash.enabledLogging()
    LastCrash.setDelegate(self)
    LastCrash.applicationInitialized()
    ...
  }

  func lastCrashDidCrash() {
    // logic to handle crash here
    LastCrash.send()
  }

}

Objective-C:

AppDelegate.h:

#import <LastCrash/LastCrash.h>
...
@interface AppDelegate : UIResponder <UIApplicationDelegate, LastCrashDelegate>

AppDelegate.m:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  ...
  [LastCrash configure:@"LASTCRASH_API_KEY"];
  [LastCrash enabledLogging];
  [LastCrash setDelegate:self];
  [LastCrash applicationInitialized];
  ...
}

- (void)lastCrashDidCrash {
  // logic here to handle crash
  [LastCrash send];
}
...

Testing

Run app in Release mode with debugging turned off. For best results, run on a physical device, rather than a simulator.

Tap Test Crash to trigger a crash. Then re-run the app and watch the output log for the crash being uploaded. Go to your LastCrash account to view the crash recording.
