All in Mobile

A few words about the project sample

The sample project is the part of our past Swift projects. This sample contains one module which is used to displays user content (statements) on 3 screens. The sample also contains the screen to create new content as a user.

Keep in mind that all requests are based on static .json files to allow you to compile the project and see all our content inside the app. To keep the sample small, we stripped down most of its features.

Rx - Reactive programming

The app implements MVVM architecture instead of MVC, which is recommended by Apple. MVVM approach is recently widely used by the iOS community. The app uses heavily the RxSwift library, which is the Swift implementation of ReactiveX.

Code style & lint

In AIM, we use SwiftLint to keep the same style guide in our Swift projects.

Continous Integration in All in Mobile

First of all, our Continuous Integration is based on the Jenkins platform which is installed locally on our machine. Each job inside Jenkins represents a version-type which has to be created. Usually, one project has 2 jobs in Jenkins. The first one is used for the Crashlytics builds for our testers and internal usage. The second job builds and sends a version to the iTunesConnect TestFlight platform, from where it is possible to publish the app on the market.

GitFlow

Continuous Integration has to be fully automated and supported by branching model, which will allow releasing new versions, hot-fixes or test builds. For that, we use GitFlow branching model which is described here. The basic setup of our branches is to have at least 2 main branches:

• develop - it is the place where developers merge their work via pull requests. Every push on this branch fires the Jenkins job and sends a version to the Crashlytics
• master - it represents the version which is available for users. Each push on this branch fires the Jenkins job to create the AppStore version and sends it there.

Fastlane

Jenkins and GitFlow represent when a version should be built and released. Fastlane is a tool which, supported by Twitter, allows to write scripts to create desired delivery process. Our basic setup covers:

• Increasing the build number
• Running unit tests (and fails on unit test fail)
• Slack notifications
• Building the version (including signing with proper certificates)
• Sending the version to the Crashlytics or Testflight/AppStore

More advanced setups allow also to create app screenshots and uploading them to the iTunesConnect (in every language which the app supports)
