I am working on a project and for some reason there is a main.storyboard and a screen.xib file both in the same objective-c project. The project is done on Xcode. To my understanding, it should only be one or the other. Am I mistaken?
An Xcode project can use a combination of .nibs, .xibs, and storyboards.
iOS uses nibs as an implementation detail that supports storyboards,
the iOS user interface design layout format. Storyboards allow you to
design and visualize the entire user interface of your app on one
canvas. For iOS developers, using storyboards is the recommended way
to design user interfaces.
*the same holds true for OS X as well, although depending on what you're creating storyboards might not be recommend.

I have an android background, but am just learning how to build iPhone apps using swift. I am using the book Beginning iPhone Development with Swift 2: Exploring the iOS SDK.
Problem is that it refers to Buttons and such being in the Object Library and I don't have anything in my object library. I have clicked on the View as instructed.
I have a newly installed MacBook and am running Xcode 8.1, which is newer than the book's directions. It refers to iOS UIkit, but I don't know how to install this.
I did Single View Application under iPhone to get where I am. Can anyone point me to what I need to do? I am brand new to the Apple world entirely.
Aha! In the main window, I clicked on the storyboard and that allowed the Object Library to contain the view items, including buttons.
So, click on the storyboard in the main window, then click on the view in the IB.
I got this error "There was a problem rendering this document" when i tried to load my storyboard in my xamarin iOS application. I created another xamarin iOS project and still got the same error.
You can not do much there right now.
There are two options one should do:
1. Use Xcode storyboard if you can.
2. If the first one is not an option, create and use multiple storyboards in your project, since after your storyboard gets big enough xamarin has a lot of problems rendering and working with it. You have a lot of documentation on how to use multiple storyboards in your project.
I am just starting out learning to build interfaces, but the book I am following is a little dated and it says that Xcode should create it for me with my new project, however it didn't. So now I need to link my buttons to my app delegate, but I can't because it isn't showing up when I right click on my buttons. And yes, I did define my methods and instance variables.
Xcode very much will create a MainWindow.xib if you choose Cocoa Application as the project type. Check to make sure you aren't either creating an iOS project or a command-line tool... both can be easy to accidentally select when you are just starting to learn.
(FYI, I just verified in Xcode 4.2.1 that a MainWindow.xib was created for me.)
Fairly new to the Xcode Developer API and need a little help. When a project is first opened in Xcode, the Object Library displays the full list of UIKit objects available (and other linked frameworks I believe). However, when I switch files in the project navigator to/from any file (.m, .h, .xib, etc), the Object Library list changes; most of the objects are missing - such as NSButton, NSTableView etc. The standard objects are still visible - Label, Round Rect Button, Text Field, etc.
Closing and re-opening the same project appears to restore the Object Library list, but the same issue happens once a different file is opened.
Using Xcode Version 4.2.1, Build 4D502.
Help!
I think I see what you are describing. When I first open an iOS project the Object Library is showing objects that are valid for OS X but not iOS (like File Menu Item). When I switch to a xib file the Object Library gets updated to show only the objects that are valid for iOS. Ideally I suppose that wouldn't happen but since you can't do anything with the Object Library while a source file is in the editor no harm is done.
If you are developing application for iOS(iPad or iPhone) you will not get that library which contains pop button , check box ,NSButton, NSTableView etc,that library is available for OS X app development.
OS and OS X don't use the same graphics library. iOS and OS X development are similar, but not the same. For example - you don't have Cocoa Bindings on iOS.
I you want to check then make one project for iOS & then see your library contents,then create another project for OSX & see your library contents... :D
Is there any way to create an app for the Mac App Store in much the same way as you do for the iPhone/iPad app store? Using Interface Builder or some similar program for creating views that will connect to the code with IBOutlets and IBActions?
If not, can anybody outline what is needed to create Mac Apps as opposed to iOS apps and perhaps point to a good tutorial, sample source code, or documentation resource?
Thanks for your help!
The technology is much the same for both Mac OS and iOS. You use Xcode and Interface Builder. iOS uses CocoaTouch whereas Mac OS X uses Cocoa (from which CocoaTouch was derived).
It's basically the same, but instead of UIViewControllers you use NSViewControllers. NSView is slightly different from UIView but the subview-mechanism is identical.
