Installation

pod 'Harlow', :configurations => ['Debug'] # Make sure to only use Harlow for development only.

Usage

#if DEBUG
import Harlow
#endif

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    #if DEBUG
    lazy var debugger: Harlow = Harlow()
    #endif

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

        #if DEBUG
        debugger.isEnabled = true
        #endif
    }
}

Other options

debugger.isDebuggingDataPersistenceEneabled = true /// Enables local data persistance
debugger.enabledServices: [Service] = [.logs, .errors] /// The services you would like to enable. Default is se to `allCases`
debugger.tintColor = .red /// Change the tint color
debugger.errorCodesExceptions = [4097] /// Add error code exceptions
debugger.isShakeEnabled = true // Defaults to `true`. When this is `true`, shaking the device will enable/disable the Debugger
debugger.isEnabled = true

Adding logs

Analytics

Option 1.

Set up your tracking payload:

public func payload() -> [String:String] {

    var payload: [String:String] = ["eventName": eventName]

    if let itemId = itemId {
        payload["itemId"] = itemId
    }

    if let category = category {
        payload["category"] = category
    }

    if let contentType = contentType {
        payload["contentType"] = contentType
    }

    if let screenName = screenName {
        payload["screenName"] = screenName
    }

    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"

    payload["createdAt"] = dateFormatter.string(from: Date())

    return payload
}

Post it to:

func post(_ payload: [String:String]) {
    let notificationCentre = NotificationCenter.default
    let notification = Notification.init(name: Notification.Name(rawValue: "io.stanwood.debugger.didReceiveAnalyticsItem"), object: nil, userInfo: payload)
    notificationCentre.post(notification)
}

Option 2.

Use StanwoodAnalytics as your tracking framework

#if DEBUG
analyticsBuilder = analyticsBuilder.setDebuggerNotifications(enabled: true)
#endif

Networking

Harlow works by default with URLSessiosn.shared and request are beeing logged for free. You can also register a custom condiguration:

let configuration = URLSessionConfiguration.waitsForConnectivity

debugger.regsiter(custom: configuration)

/// Use with URLSession || any networking libraries such as Alamofire and Moya
let session = URLSession(configuration: configuration)

Error

Harlow will log NSError by default. To add log exceptions:

debugger.errorCodesExceptions = [4097] /// Add error code exceptions

Logs

Harlow will log print && debugPrint by default.

Configuration:

1. Create a new Bridging-Header file and add -DEBUG suffix

2. Import Harlow

@import Harlow;

Note: Make sure to add any other imported libraries from your main header file

3. Set Bridging-Header-DEBUG.h in the relevant configurations in the build settings.
