Python has a couple of alternative ways of writing necessary statements. Doing an import abc seems to be up abc within the sys.modules and if it isn’t out there, Python will proceed to go looking by means of a listing of pre-installed built-in modules.
One other syntax of importing modules or submodules when it belongs to a different package deal: from xyz import abc.
Whereas utilizing a easy import assertion is probably the most identified manner of utilizing frameworks in your Swift codebase, you can too import submodules or courses or structs just like what we did in Python. Swift import statements assist the next syntaxes:
//Swiftimport [module]
import [module].[submodule]
import [import kind] [module].[symbol name]
Right here’s an instance of import submodules in Swift:
import UIKit.UITableViewController let tableVC = UITableViewController()
let vc = UIViewController() //works//orimport class UIKit.UITableViewController let tableVC = UITableViewController()
let vc = UIViewController() //error
Take notice, the second import assertion would throw an error when utilizing UIViewController. It is because we’re solely importing class with the image title UITableViewController.
One other attention-grabbing factor in Swift is that you simply can’t rename the imported useful resource as you’d do in Python: import abc as a. As a workaround, you should utilize typealias after the import assertion in Swift.
