What is Xcode doing when it is Indexing?
You will lose features such as
- Autocomplete
- Ability to quickly jump to definition
- Get class and method help by alt clicking.
So, its recommended that let indexing get complete, so you could work smoothly in above areas.
Thanks.
Indexing in Xcode helps to
- speed up searching within project,
- autocompletion (if you for example add a method to your class, it helps you to use it in other part of your project in seconds without remembering its full name etc.),
- suggestions
Trigger events are for example:
- creating your own class
- implementation of a framework
- importing a module
- connecting a segue
- outlet connection with a view controller
It also depends on specific situation.
If you clean your project / build folder, it can reindex the project.
