Sentinel is a simple library that gives developers the possibility to configure one entry point for every debug tool. The idea of Sentinel is to give the ability to developers to configure a screen with multiple debug tools which are available via some event (e.g. shake, notification).
Sentinel has a tab bar that contains five screens. Three of those aren't configurable, and two of them are. The first screen is the Device screen which allows the user to look into some of the device-specific information. The second screen is the Application screen which allows the user to look into some of the application-specific information from the info.plist. The third, the first configurable screen, is the Tools screen. Tools screen allows you to add as much Tool object as your heart desires which can be used by the user to find out some specific information. The fourth, last configurable screen, is the Preferences screen. Preferences screen allows you to add options that allow or deny some activity inside the app. The last, but not the least, is the Performance screen which contains performance-specific information. Later on, we'll explain how you can configure those screens.
This library supports both Swift and Objective-C.
- iOS 10 and above
- Xcode 10 and above
Sentinel is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'Sentinel'If you are using SPM for your dependency manager, add this to the dependencies in your Package.swift file:
dependencies: [
.package(url: "https://github.com/infinum/ios-sentinel.git")
]To add the Sentinel to your project, install the library as instructed above. After that, define Sentinel configuration with mandatory parameters and call Sentinel.shared.setup: in the AppDelegate method application(_:didFinishLaunchingWithOptions:).
let configuration = Sentinel.Configuration(
sourceScreenProvider: SourceScreenProviders.default,
trigger: Triggers.shake,
tools: [
GeneralInfoTool(),
UserDefaultsTool(),
LoggieTool(),
],
preferences: [
OptionSwitchItem(
name: "Analytics",
setter: { AppSwitches.analyticsEnabled = $0 },
getter: { AppSwitches.analyticsEnabled },
userDefaults: .standard,
userDefaultsKey: "com.infinum.sentinel.optionSwitch.analytics"
)
]
)
Sentinel.shared.setup(with: configuration)Sentinel is the main class used to setup the Sentinel which will be used in the application. The Sentinel object can configured via setup: method by Configuration object.
To be able to configure the Sentinel object, the Configuration object is introduced. This object contains multiple objects which define general Sentinel behaviour. The inputs which this object needs are; trigger, sourceScreenProvider, tools, and preferences.
The trigger object is a type of Trigger which defines on which event the Sentinel will be triggered. Currently, three types of are supported; ShakeTrigger, ScreenshotTrigger, NotificationTrigger. New triggers can be added as well, just by conforming the Trigger protocol.
The sourceScreenProvider object is a type of SourceScreenProvider which should provide a view controller from where will Sentinel be presented. Currently, one type is supported; default.
The tools object is an array of Tool objects. Tool objects represent tools which will be available from Sentinel. There are multiple tools already supported by the library, but custom tools can be created and added to the Sentinel.
The last, but not the least, is the preferences object which is an array of OptionSwitchItem objects. OptionSwitchItem is used to allow the user to switch of some of the preferences which are contained in the app. e.g. The app supports Analitycs and you can add an OptionSwitchTool which will be shown on the Preferences screen and the user can turn it off if he doesn't want it.
To be able to create a custom tool that will be available through the Sentinel, a new class should be created which conforms the Tool protocol. This protocol is defined as:
public protocol Tool {
var name: String { get }
func presentPreview(from viewController: UIViewController)
}Based on this, only name should be provided as well as presentPreview: method which will present the tool view controller from the sourceScreenProvider view controller defined in the Sentinel configuration.
A common custom tool that might be needed is Pulse network logger. It can be defined in the following way:
class PulseTool: Tool {
var name: String { "Pulse" }
func presentPreview(from viewController: UIViewController) {
let pulse = UIHostingController(rootView: ConsoleView())
let pulseNavigation = UINavigationController(rootViewController: pulse)
viewController.present(pulseNavigation, animated: true)
}
