Cocoa is the application environment that unlocks the full power of OS X. Cocoa provides APIs, libraries, and runtimes that help you create fast, exciting apps that automatically inherit the beautiful look and feel of OS X, as well as standard behaviors users expect.

Cocoa Helps You Create Great Apps for OS X

You write apps for OS X using Cocoa, which provides a significant amount of infrastructure for your program. Fundamental design patterns are used throughout Cocoa to enable your app to interface seamlessly with subsystem frameworks, and core application objects provide key behaviors to support simplicity and extensibility in app architecture. Key parts of the Cocoa environment are designed particularly to support ease of use, one of the most important aspects of successful Mac apps. Many apps should adopt iCloud to provide a more coherent user experience by eliminating the need to synchronize data explicitly between devices.

Common Behaviors Make Apps Complete

During the design phase of creating your app, you need to think about how to implement certain features that users expect in well-formed Mac apps. Integrating these features into your app architecture can have an impact on the user experience: accessibility, preferences, Spotlight, services, resolution independence, fast user switching, and the Dock. Enabling your app to assume full-screen mode, taking over the entire screen, provides users with a more immersive, cinematic experience and enables them to concentrate fully on their content without distractions.

Get It Right: Meet System and App Store Requirements

Configuring your app properly is an important part of the development process. Mac apps use a structured directory called a bundle to manage their code and resource files. And although most of the files are custom and exist to support your app, some are required by the system or the App Store and must be configured properly. The application bundle also contains the resources you need to provide to internationalize your app to support multiple languages.

Finish Your App with Performance Tuning

As you develop your app and your project code stabilizes, you can begin performance tuning. Of course, you want your app to launch and respond to the user’s commands as quickly as possible. A responsive app fits easily into the user’s workflow and gives an impression of being well crafted. You can improve the performance of your app by speeding up launch time and decreasing your app’s code footprint.

How to Use This Document

This guide introduces you to the most important technologies that go into writing an app. In this guide you will see the whole landscape of what's needed to write one. That is, this guide shows you all the 'pieces' you need and how they fit together. There are important aspects of app design that this guide does not cover, such as user interface design. However, this guide includes many links to other documents that provide details about the technologies it introduces, as well as links to tutorials that provide a hands-on approach.

In addition, this guide emphasizes certain technologies introduced in OS X v10.7, which provide essential capabilities that set your app apart from older ones and give it remarkable ease of use, bringing some of the best features from iOS to OS X.

Ulysses

The first three apps on this list all take a similar no-frills approach to writing. They sport clean, minimalist interfaces, keep all your writing in a single window, can swap documents between their iOS and Mac versions, and use some variation of the Markdown syntax to handle all text formatting.

Ulysses impressed me most among this crowd for its breadth of features and ease of use. An outstanding series of introductory texts ease you into using Ulysses, one simple step at a time. Their witty writing allows you to learn the program while you're using it.

If you want to track your own productivity, or challenge yourself to meet a certain word count, it's easy to set goals from Ulysses's dashboard. Don't know Markdown XL, Ulysses's native tongue? No worries — a handy cheat sheet of syntax waits behind a button at the top of the program. (Ulysses also supports old faithful keyboard shortcuts for bold, italic, and linked text, if you don't want to type Markdown XL's extra characters.)

Ulysses keeps these two features and a handful of others, including options to export your work to text, ePub, HTML, PDF, or DOCX formats, in pop-over menus that you can tear off and keep onscreen for easy reference.

Ulysses isn't WYSIWYG; you can download themes to change up its color scheme at the Ulysses Style Exchange, but you can't view the effects of your formatting until you preview or export it. The Style Exchange also offers a host of free templates for PDF, HTML, and ePub exports, with different looks, fonts, and styles.

Ulysses comes with built-in iCloud support to hand off documents between its Mac and iOS versions. It can also publish your work directly to your Medium or WordPress site, once you enter your account info. And its subscription model means that your monthly $4.99 fee unlocks the app on both the Mac and iOS.

Ulysses offers a lot of options in a polished, user-friendly package. Unfortunately, it has a good portion of its thunder stolen by…

Bear

Nearly everything Ulysses does, Bear does just as well, in an arguably prettier package. Bear's fonts and color scheme, while still clean and stark, go easier on the eyes than Ulysses's utilitarian gray. Its stats panel is much easier to read, though less detailed. And Bear strikes a happy medium between full WYSIWYG formatting and Markdown simplicity by clearly labeling different header tags as you create them, and offering the option to actually show text as bold or italic when properly marked.

I liked Bear's tagging system, which makes it really easy to organize files. Just type in a hashtag anywhere in your document, and Bear will either create a category for it on the fly in its list of documents, or add that document to an existing category. I was also impressed with Bear's ability to share a note to any program you've added to your Mac's Sharing menu, including Facebook, Twitter, and Reminders.

Beyond that, Bear duplicates a lot of Ulysses's virtues, from its overall interface to its friendly help files. And the program's basic version, which packs plenty of power, is absolutely free on both Mac and iOS. However, to match Ulysses's features, you'll need to subscribe to Bear Plus, for $1.49 a month or $14.99 a year. That subscription gets you features like iCloud synching, ePub export, and customizable export themes, all of which Ulysses includes right out of the box.

iA Writer

iA Writer is inexpensive -- just a one-time $15 fee -- and it packs a reasonably robust feature set. iCloud sharing and synching with its iOS sibling is built in, as is WordPress and Medium support. Like Bear and Ulysses, iA Writer offers downloadable export templates, and its help files include instructions to make your own with HTML, CSS, and JavaScript. But for all these virtues, iA Writer still falls short.

Its stark black-and-white interface makes Ulysses look colorful. It feels brusque and utilitarian, not welcoming. On first use, the program dumps you right into its interface with no introduction. Its lean, efficient Help files explain the program well, but after Ulysses and Bear's gentler tutorials, iA Writer's lack of frills can feel jarring.

Word count and other stats are crammed into a tiny menu at the bottom of the window, and you can't set goals for any of those parameters. They're squeezed into the same small space as iA Writer's Format and Syntax menus, which can format text or quickly highlight all the nouns, adverbs, adjectives, or other parts of speech in your document — a nifty feature undercut by lackluster interface design.

Finally, a real-time preview window can show you what your text will look like when it's finished and formatted. But it feels odd to have the same text side by side; if you want to see what text looks like when formatted, why not just have a WYSIWYG editor?

iA Writer isn't bad on its own merits, but with such impressive competition, it can't help but suffer in comparison.

Scrivener

How To Write Apps For Mac Free

At the opposite end of the spectrum from its spartan rivals, Scrivener is a jumbo-sized Swiss army knife stuffed with a sometimes overwhelming array of fun and useful tools. The other programs in this roundup are undeniably more versatile, lending themselves just as well to note taking, blog posts, journalism, or technical writing as they do to writing fiction. In contrast, Scrivener's built to serve the needs of folks writing novels, short stories, screenplays, and — given its ability to store pictures, cached web pages, and other research material alongside a given text — possibly term papers. For $45, you'll definitely get your money's worth.

Scrivener's somewhat long in the tooth compared to its rivals here, with a dense but coherent interface filled with the kinds of colorful icons that seem to have fallen out of fashion among Mac apps. It arguably needs such a crowd of buttons to display even a fraction of the features stuffed into its every nook and cranny. (My favorite: A ridiculously options-laden name generator for authors in need of inspiration.) Scrivener's user manual, however engagingly written, is 546 pages long. It's not messing around.

Even after years of using Scrivener, I still sometimes find myself hunting through its menus in search of that one command I need. Consistently formatting text files in a given project to anything other than Scrivener's default settings can be a pain, and it keeps its settings for targets and statistics in separate popup windows.

But despite this complexity, Scrivener does a good job of getting out of your way. Scrivener offers an outline mode, and a corkboard mode that displays each of your scenes as virtual notecards on which you can hash out what happens when. But if you just want to start writing without worrying about its bells and whistles, you won't have a problem. Because it's so like the Finder, Scrivener's system for storing scenes in various folders makes sense immediately. And like all the programs mentioned here, Scrivener offers a fullscreen mode that blots out everything but the text you're working on, to avoid distractions.

Scrivener also offers a respectable if occasionally glitchy screenplay mode. It won't replace Final Draft, but if you want to have fun writing a cinematic masterpiece about Dominic Toretto battling Dracula, you'll end up with a decently formatted final product.

Scrivener also shines when it's time to publish your work. Its voluminous list of export formats includes all the usual suspects, plus ePubs, Final Draft screenplay files, and even Kindle books. You can even select only specific chapters or files to compile and export — handy when you've got multiple drafts of a novel in a given file, but only want to create a PDF of the most recent one. However, this versatility has one glaring exception: Scrivener doesn't support iCloud, though it can share documents between its iOS and Mac versions.

Which app is best?

How To Write Apps For Mac Pro

If you want a jack-of-all trades writing app with WordPress, Medium, and iCloud support built in, Ulysses is your best bet. If you're not willing to shell out $4.99 a month indefinitely, try the similar Bear first. You may not ever need its advanced features, which would give you a terrific writing app for free.

But if you're serious about creative writing, and you want a stalwart companion to help drag stories out of your brain, Scrivener's your best bet. Its learning curve is steeper, but its powerful features make that climb worthwhile.
