Podcast Do polyglots have an edge when it comes to mastering programming Featured on Meta. Now live: A fully responsive profile. Linked 1. Each subsequent test run compares performance, displays the change over time, and—by highlighting the problem area—alerts you to sudden regressions a code commit could introduce. Asynchronous code testing. You can now create tests for network operations, file IO, and other system interactions that execute using asynchronous calls in a straightforward and simple manner.
For more information, see Testing with Xcode. Live rendering. Interface Builder displays your custom objects at design time exactly as they appear when your app is run. When you update the code for your custom view, the Interface Builder design canvas updates automatically with the new look you just entered in the source editor, with no need to build and run. You can use the Interface Builder inspector to see properties automatically as well.
Take advantage of new APIs that allow you to customize the behavior of custom controls on the Interface Builder canvas—for instance, you can load sample data on the fly.
Size classes. Size classes for iOS 8 enable designing a single universal storyboard with customized layouts for both iPhone and iPad. With size classes you can define common views and constraints once, and then add variations for each supported form factor. Custom iOS fonts. Interface Builder renders embedded custom fonts during design time, giving a more accurate preview of how the finished app will look, with correct dimensions.
View debugging. Using the view debugger makes it immediately obvious why an image may be clipped and invisible, and the order of the graphical elements becomes clear. By selecting any view, you can inspect the details by jumping to the relevant code in the assistant editor source view. The view debugger also displays Auto Layout constraints, making it easy to see where conflicts cause problems.
Enhanced queue debugging. The debug navigator records and displays recently executed blocks, as well as enqueued blocks. Debug gauges. Debug gauges provide at-a-glance information about resource usage while debugging. They call your attention to previously unknown problems, especially related to areas that could create poor user experience or drain excess battery on portable Mac computers and devices. The iCloud debug gauge includes support for the new Documents in the Cloud and CloudKit features that provide access to files outside the app-specific container.
Graphics and game development. Support for SpriteKit has been significantly enhanced with a new SpriteKit level designer and improved display of SpriteKit variables when debugging. Support for iOS.
Create scenes for your SpriteKit games from within Xcode. It is easier than ever to define how your characters, backgrounds, and the rest of your game comes together—it has never been easier to share code when creating great games for both iOS and OS X. Extensions support. Xcode connects to the extension when launched, debugging the extension as it runs in the safe, embedded OS context.
Frameworks for iOS. Frameworks are a collection of code and resources to encapsulate functionality that is valuable across multiple projects. Frameworks work perfectly with extensions, sharing logic that can be used by both the main application and the bundled extensions. For more information, see App Extension Programming Guide. New iOS Simulator configurations allow you to keep data and configuration settings grouped together. Run one configuration for one version of an app, with its own data, and another configuration for a different app version.
XLIFF import-export. Xcode can package your localizable strings into the industry standard XLIFF format to send off for localization. Xcode automatically generates the base language. Preview in Interface Builder. While designing in Interface Builder, the preview assistant can show how the interface appears in other languages. You can see how your interface responds to longer or shorter languages.
Run in locale. Xcode can run your app on iOS Simulator, or directly on devices, as it would appear to customers in other countries.
For more information on Xcode 6 localization, see Internationalization and Localization Guide. Profile Guided Optimization. You can also exercise your app manually to generate a performance profile.
PGO uses the profile to further optimize your app, targeting the areas that most need optimization, improving performance beyond what setting optimization options alone can achieve. Downloading 7. The modern Interface Builder though is hobbled by concepts that IMO were quickly surpassed by other, easier concepts.
SuperCard had a better layout system in the late 90's, that properly scaled pretty much anything for any resolution. Search by keywords or tags Submit Search Clear search query Additional information about Search by keywords or tags Supported Searches:. Interface Builder is bad and getting worse.
Click again to start watching. Hi, I've been a Mac developer since the late 80's. And if I'm having problems with this, I guarantee this is a stumbling block for new users. Interface Builder.

Post marked as solved. Posted by bob It adds unwanted complexity. Hence your post. My opinion only of course.
You're free to do as you wish. Let me guess - Autolayout? Posted by jpdev Posted by donarb. If you do not, then spend the time you waste in Interface Builder laying out your UI in code. Posted by Floating Wrench. Hi, I do agree that IB isn't great at all, but for many things, not that bad either, provided that you learn how to use it. I'd understand people doing everything in code Not only, but it helps in many other points: - Portability: You can duplicate a view very quickly, and modify the class attached to it pretty good when you have a custom template - Memory leaks: Many elements can be controlled purely in IB with no need to have them as property in code, which reduces the risks of memory leaks.
Posted by EinharchAltPlus. They certainly don't have a lock on interface design. Because of forum rules, I won't tell you what I suggest you do. No need to get on the offensive, there was nothing personal in my comment. I'm hesitant to adopt Autolayout in my apps though. Posted by Macho Man Randy Savage. I've been fighting with autolayout since 7.
