Integrate sentry into your swift application.

// AppDelegate.swift

import Sentry

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        // Create a Sentry client and start crash handler
        do {
            Client.shared = try Client(dsn: "https://515b3example:5d302example@sentry.io/123456")
            try Client.shared?.startCrashHandler()
        } catch let error {
            print("(error)")
            // Wrong DSN or KSCrash not installed
        }

        return true
    }

    .
    .

}

The sentry listener will automagically send the stack trace when the app crashes. But what if you want to send arbitrary messages whenever you want?

// SomeView.swift

import Sentry

func someFunction() {
    let tokenEvent = Event(level: .debug)
    tokenEvent.message = "localToken"
    tokenEvent.extra = ["localToken": localStorage.value(forKey: "token") as! String]
    Client.shared?.send(event: tokenEvent) { (error) in
        // Optional callback after event has been send
        print("localToken sent")
    }

    let someEvent = Event(level: .debug)
    someEvent.message = "something"
    someEvent.extra = ["something": "wow so cool"]
    Client.shared?.send(event: someEvent) { (error) in
        // Optional callback after event has been send
        print("someEvent sent")
    }
}

There’s probs more but this is all I used it for so far…
