Being with iOS on fastlane

About me

Things to consider

• Enterprise app - not deployed on App Store
• 2 devs cranking out the product for iOS
• Different urls and configuration for different purposes - dev, staging, production
• Talks to a SOAP API
• Fairly complex with offline update and "sync when online" mechanism
• Backed by CoreData

Where did we begin

• A fairly manual build and archive process involving Xcode
• ~ 30 mins of work
• Mailing the built .ipa to the testers for testing
• Few test cases either didn't run or were misconfigured
• Swift 2.3

Where did we want to get to

• Testers be able to test the code, as and when they want
• Developers be able to quickly build and publish an ipa
• Stable codebase with good test coverage
• Minimum setup required for new developers

Let's talk about the journey

Dealing with multiple environments

enum Environment: String {
  case Develop = "Develop"
  case Testing = "Testing"
  case Production = "Production"

  var baseURL: String {
    switch self {
      case .Production: return "https://prod.eam360.com"
      default: return "http://dev.eam360.com"
    }
  }


  var pubnubPubKey:  String {
    return "pub-c-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  }

  var pubnubSubKey:  String {
    return "sub-c-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  }

  var logLevel: XCGLogger.Level {
    switch self {
      case .Production: return .error
      default: return .debug
    }
  }
}

struct EnvironmentConfig {
  lazy var environment: Environment = {
    if let configuration = Bundle.main.object(forInfoDictionaryKey: "Configuration") as? String {
      switch configuration {
        case "Production": return Environment.Production
        case "Testing": return Environment.Testing
        default: return Environment.Develop
      }
    }

    return Environment.Develop
  }()
}

Testing

• Quick / Nimble
• Calabash

Last but not least

• Cocoapods
• Carthage

Where are we?

• Testers be able to test the code, as and when they want - Done
• Developers be able to quickly build and publish an ipa - Done
• Stable codebase with good test coverage - In progress
• Minimum setup required for new developers - We need new developers to come and test this for us! ;)
