How To Build iOS Apps Without interface Builder
This document discusses the benefits of building iOS apps without Interface Builder including avoiding context shifts, inheritance issues, and performance problems when using constraints and storyboards. It provides code examples for initializing a window and navigation controller programmatically in AppDelegate, loading views directly in code instead of a storyboard, and demo apps using common UI elements like login screens and table views without Interface Builder.
How To Build iOS Apps Without interface Builder

- 3. IB vs. Code(I) • Context shift • More evil conflicts • Options all over the place • Harder to get help • No betas for you
- 4. IB vs. Code(II) • No inheritance • Harder to DRY • Hard to see contraints • Really bad performance

- 6. AppDelegate.swift import UIKit @UIApplicationMain class AppDelegate:UIResponder, UIApplicationDelegate { var window: UIWindow? = UIWindow(frame: UIScreen.mainScreen().bounds) func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { window?.rootViewController = ViewController() window?.makeKeyAndVisible() return true } }
- 7. UINavigationController import UIKit @UIApplicationMain class AppDelegate:UIResponder, UIApplicationDelegate { var window: UIWindow? = UIWindow(frame: UIScreen.mainScreen().bounds) func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { window?.rootViewController = UINavigationController(rootViewController: ViewController()) window?.makeKeyAndVisible() return true } }
- 8. Loading The View overridefunc loadView() { view = FirstView() }
- 9. Demo • Login-Screen • AutoLayout • UIStackView • UITableView / UITableViewCell • UINavigationController • UITabBarController
