Create environments in iOS app(Swift)

So what is environment..??🤔
An environment is a area, scope or place for developing, testing and debugging an application or program.

Basically we have 3 environments,
1: Development

2: Pre-Production

3: Production

Sometimes we need to seperate the base url and do the initial work, Which should be done for that state or condition only.

1: Create enum to differentiate environments

enum Environment {
case development
case preProduction
case production
}

2: Create the environment variable

let currentEnvironment = Environment.development

3: Use switch to execute different branches of code based on certain conditions

switch currentEnvironment {
case .development:
print("do the code which you want to execute only if the environment is development")
case .preProduction:
print("do the code which you want to execute only if the environment is preProduction")
case .production:
print("do the code which you want to execute only if the environment is production")
default:
break
}

4: Where you can use this code ?

Well you can use it anywhere in the project,
just initialize the currentEnvironment variable and using conditions use it.
like i use to change the baseUrl in AppDelegate

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
let currentEnvironment = Environment.development
switch currentEnvironment {
case .development:
baseUrl = "developmentBaseUrl"
case .preProduction:
baseUrl = "preProductionBaseUrl"
case .production:
baseUrl = "productionBaseUrl"
default:
break
}
return true
}
