Working w/Environments in Swift

According to Wikipedia, an Environment Variable is a dynamic-named value that can affect the way running processes will behave on a computer. They are part of the environment in which a process runs. Basically, many developers create 3 environments

• Dev
• Preprod
• Prod

Sometimes we need to separate the base URL and do the initial work which should be done for the following state or condition only.

Create enum for environments

if you need a refresher on enum check out the following article

enum Environment { 
   case dev 
   case preprod 
   case prod 
}

Environment Variable

let currentEnvironment = Environment.dev

Execute using a switch statement

switch currentEnvironment {
   case .dev:
       print("execute only if the environment is development")
   case .preprod:
       print("execute only if the environment is preprod")
   case .prod:
       print("execute only if the environment is prod")
   default:
   break
}

Execute code now

First, we initialize the currentEnvironment variable and using conditions use it. Now we can change the baseUrl in AppDelegate along with other interesting code.
