AppDebugMode

Swift Package AppDebugMode is a library that allows an iOS application to select an API Server and User for the app during runtime. This can be helpful during development and testing phases of the application. With AppDebugMode, developers and testers can easily switch between development, staging, and production environments without recompiling the application. Additionally, it allows developers and testers to select different users test different scenarios in the app.

Instalation

1. Add Swift Package

/// Package.swift
dependencies: [
    .package(url: "[email protected]:GoodRequest/AppDebugMode-iOS.git", .upToNextMajor(from: "1.2.0"))
]

2. Exclude AppDebugMode package from Release sceheme

Setup

/// AppDelegate.swift
#if DEBUG
import AppDebugMode
#endif

#if DEBUG
    enum ServersCollections {

        static let myAppBackend = ApiServerCollection(
            name: "My App backend",
            servers: [
                Servers.prod,
                Servers.dev
            ],
            defaultSelectedServer: Servers.dev
        )

        static var allCases: [ApiServerCollection] = [
            Self.myAppBackend
        ]

    }

    enum Servers {
        
        static let prod = ApiServer(name: "PROD", url: "https://api.production.example")
        static let dev = ApiServer(name: "DEV", url: "https://test.api")
        
    }
#endif

// `didFinishLaunchingWithOptions` (before starting coordinator):
#if DEBUG
    AppDebugModeProvider.shared.setup(
        serversCollections: ServersCollections.allCases,
        onServerChange: { 
            // logout user
        }
    )
#endif

Get selected server

#if DEBUG
import AppDebugMode
#endif

var baseURL: String {
    #if DEBUG
    return AppDebugModeProvider.shared.getSelectedServer(for: ServersCollections.myAppBackend).url
    #else
    return "https://api.production.example"
    #endif
}

Get selected user

#if DEBUG
import AppDebugMode
#endif

#if DEBUG
    AppDebugModeProvider.shared.selectedTestingUserPublisher
        .sink { [weak self] in
            self?.emailTextField.text = $0?.name
            self?.passwordTextField.text = $0?.password
        }
        .store(in: &cancellables)
#endif

Cache setup

Warning: To ensure the proper functioning of the cache manager, you need to utilize the GoodPersistence properties in your cache manager.

/// AppDelegate.swift
#if DEBUG
    AppDebugModeProvider.shared.setup(
        serversCollections: ServersCollections.allCases,
        onServerChange: { 
            // logout user
        },
        cacheManager: // optional - provide your own cache manager
    )
#endif

Push notifications

If you want to use push notifications in debug mode, you need to pass Messaging.Messaging() object into AppDebugModeProvider.shared.setup() method.

// didFinishLaunchingWithOptions

// essential configuration
FirebaseConfiguration.shared.setLoggerLevel(.min)
FirebaseApp.configure()

#if DEBUG
AppDebugModeProvider.shared.setup(
    serversCollections: C.ServersCollections.allCases,
    onServerChange: { },
    cacheManager: dependencyContainer.cacheManager,
    firebaseMessaging: Messaging.messaging() // Firebase messaging object
)
#endif

Console logs redirection

If you want to redirect logs call this snippet of code in appdelegate or a different prefered spot in if it's turned on in the app debug mode settings and if you are in a DEBUG configuration

// didFinishLaunchingWithOptions

#if DEBUG

if StandardOutputService.shared.shouldRedirectLogsToAppDebugView {
    StandardOutputService.shared.redirectLogsToAppDebugView()
}

#endif

Debugman connection

If you want to enable app to send logs to Debugman you need to add following to your Info.plist file.

<key>NSBonjourServices</key>
<array>
    <string>_Debugman._tcp</string>
</array>
<key>NSLocalNetworkUsageDescription</key>
<string>Proxy and debugger connection when running in DEBUG mode</string>

To enable proxy for Debugman you need to add AppDebugMode Proxy URL Sessiion Config to your Network session.

#if DEBUG
let urlSessionConfig = AppDebugModeProvider.shared.proxySettingsProvider.urlSessionConfiguration
#else
let urlSessionConfig = URLSessionConfiguration.default
#endif

session = NetworkSession(
    baseUrl: baseServer.rawValue,
    configuration: NetworkSessionConfiguration(
        urlSessionConfiguration: urlSessionConfig,
        interceptor: nil,
        eventMonitors: [monitor]
    )
)

Activation in App

• In app you can activate debug mode by shaking device or in simulator by CMD + CTRL + Z
• To open debug mode with other actions in the app initialize ViewController with let debugViewController = AppDebugModeProvider.shared.start()
