Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate Mercuryo Widget into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'MRCRWidget'

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate Mercuryo Widget into your Xcode project using Carthage, specify it in your Cartfile:

github "mercuryoio/Mercuryo-Widget-Wrapper-iOS" ~> 1.0

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but Mercuryo Widget does support its use on supported platforms.

Once you have your Swift package set up, adding MRCRWidget as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/mercuryoio/Mercuryo-Widget-Wrapper-iOS.git", .upToNextMajor(from: "1.0.0"))
]

Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate Mercuryo Widget into your project manually.

Embedded Framework

Open up Terminal, cd into your top-level project directory, and run the following command “if” your project is not initialized as a git repository:

$ git init

Add Mercuryo Widget as a git submodule by running the following command:

$ git submodule add https://github.com/mercuryoio/Mercuryo-Widget-Wrapper-iOS.git

Open the new MRCRWidget folder, and drag the MRCRWidget.xcodeproj into the Project Navigator of your application’s Xcode project.

It should appear nested underneath your application’s blue project icon. Whether it is above or below all the other Xcode groups does not matter.
Select the MRCRWidget.xcodeproj in the Project Navigator and verify the deployment target matches that of your application target.
Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the “Targets” heading in the sidebar.
In the tab bar at the top of that window, open the “General” panel.
Click on the + button under the “Embedded Binaries” section.
You will see MRCRWidget.xcodeproj folder.
And that’s it!

The MRCRWidget.framework is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.

Usage

For the first, you should create a configuration for your widget. You can choose one of the standard environment production or sandbox

import MRCRWidget

do {
    let configuration = try WidgetConfiguration(
        widgetId: "67710925-8b40-4767-846e-3b88db69f04d",
        environment: .production,
        params: nil
    )
} catch {
    assertionFailure(error.localizedDescription)
}

or use your own widget url

import MRCRWidget

do {
    let configuration = try WidgetConfiguration(
        widgetId: "67710925-8b40-4767-846e-3b88db69f04d",
        widgetURL: URL(string: "https://exchange.mydomain.io"),
        params: nil
    )
} catch {
    assertionFailure(error.localizedDescription)
}

Next, you should create WidgetAssembly and call build method. It returns a ViewController that you can show as you want.

import MRCRWidget

let vc = WidgetAssembly(
    configuration: configuration,
    uiDelegate: self
)
    .build()

self.present(
    vc,
    animated: true
)

You can also support the error handling from Mercuryo Widget. Just implement WidgetUIDelegate.

import MRCRWidget

extension ViewController: WidgetUIDelegate {

    func widgetDidReceiveError(_ error: WidgetError) {
        switch error.errorCode {
        case .photoLibraryAuthorizationFailed:
            showAlert()

        default:
            break
        }
    }
}
