Create multiple targets in Xcode

When we write some code, we don’t think about reusable code.Just start to create multiple copies of that project. Many of times we need same code or classes in different projects then we start making copies of that files and moving that copies here and there. There is the solution to use single project creates multiple targets for that.Here question arises what are targets.So here are the steps to create and use multiple targets in Xcode:-

• Click .proj  file in Xcode. right click on that create a duplicate copy of the existing target.

• You can also change a name of the new target and new info.plist file generated for that target.Go to the build settings and search for info.plist enter your .plist file name

• Then again go to the build settings of the original one target. Search for preprocessor macros Add your macros MARKETPLACE=0 you can also change according to your need.

• Then go to the build settings of the copied one target. Search for preprocessor macros Add your macros MARKETPLACE=1 you can also change according to your need.

• Search for other swift flags in copied target -DMARKETPLACE because swift doesn’t support macros directly

• How to know which target is selectable in code:-
  
  1 2 3 4 5 6 7 8 9 10 11

  enum EnvironmentType {     case normal, marketplace }   #if MARKETPLACE     static let serverUrl = "Your Url"     static let environment:EnvironmentType = .marketplace #else     static let serverUrl = "Your Url"     static let environment:EnvironmentType = .normal #endif

  
  You have created only two targets that’s why it contains only 2 cases you can add much more to it.
• So each target has its own .plist file so you can easily differentiate App icon, LaunchScreen and bundle identifier according to your need.
• If you have implemented firebase in your project assign different  GoogleService-Info.plist to each target
  
  1 2 3 4 5 6 7 8 9 10 11 12

  switch environment { case .marketplace:     let filePath = Bundle.main.path(forResource: "GoogleService-InfoMP", ofType: "plist")     if let options = FirebaseOptions(contentsOfFile: filePath!) {         FirebaseApp.configure(options: options)     } case .mobikul:     let filePath = Bundle.main.path(forResource: "GoogleService-Info", ofType: "plist")!     if  let options = FirebaseOptions(contentsOfFile: filePath) {         FirebaseApp.configure(options: options)     } }

  
   

  So you have successfully added a stretchy header in your app.
