Create custom Xcode templates
Everytime we create a new file, Xcode suggests some built-in templates that may be useful. Luckily, we could also create our own templates.
Technically, Xcode looks for templates in ~/Library/Developer/Xcode/Templates and /Applications/Xcode.app/Contents/Developer/Library/Xcode/Templates. Let’s call the first path P1 and the second path P2. A template could be iferred by a folder MY_TEMPLATE.xctemplate.
Assume we gonna create a template for MVVM. It should create 3 files: [Feature]Model.swift, [Feature]ViewModel.swift and [Feature]ViewController.swift. Ex: LoginModel.swift, LoginViewModel.swift and LoginViewController.swift
- First of all, create a xctemplate folder in P1:
~/Library/Developer/Xcode/Templates/Custom/MVVM.xctemplate. Note: we should place the xctemplate folder in P1 instead of P2 b/c P2 is only particular for a specific version of Xcode. - The folder should include these files (you could copy it from P2 and modify it a little bit):
___FILEBASENAME___Model.swift___FILEBASENAME___ViewModel.swift___FILEBASENAME___ViewController.swift
- Create placeholder for the 3 files above. Here is the sample for
___FILEBASENAME__ViewController.swift:
//
// ___FILENAME___
// ___PROJECTNAME___
//
// Created by ___FULLUSERNAME___ on ___DATE___.
//___COPYRIGHT___
//
import Foundation
import UIKie
public class ___FILEBASENAMEASIDENTIFIER___ViewController: UIViewController {
private let viewModel: ___FILEBASENAMEASIDENTIFIER___ViewModel
public init(viewModel: ___FILEBASENAMEASIDENTIFIER___ViewModel) {
self.viewModel = viewModel
super.init(nibName: nil, bundle: nil)
// Initialization goes here
}
public required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
And then, magic happens :D
