Does anyone know of a good tutorial on iPhone GUI design using just code and not Interface Builder?
I am new to iPhone development, and I wanted to better understand what is going on behind the scenes.
Interface Builder is a software development application for Apple's macOS operating system. It is part of Xcode (formerly Project Builder), the Apple Developer developer's toolset. Interface Builder allows Cocoa and Carbon developers to create interfaces for applications using a graphical user interface.
To create a project in UIKit programmatically, we create a new Xcode project and initially select Storyboard as we did before. Xcode creates a storyboard by default and makes it the initial screen. We go to Project Navigator and remove any references to Storyboard. We also make some configuration changes to Info.
First, in Xcode, go to the Resources folder from the tree view on the left and select MainMenu. xib . It will open in the main view. This is where you are going to build you UI.
SwiftUI is a user interface toolkit that lets us design apps in a declarative way. That's a fancy way of saying that we tell SwiftUI how we want our user interface to look and work, and it figures out how to make that happen as the user interacts with it.
Check out the UI Catalog example in the SDK.
It showcases all of the individual controls being used in multiple ways. All of the screens, the view controllers and the navigation bars are generated from code.
