Jul 28, 2015 I found a question on Stack Overflow in which someone suggested that the asker look in the application's bundle to verify that the file that the asker's application was unable to access is actually in the bundle. He said to look in the 'Products' subfolder of the app's derived data folder. Aug 22, 2014 Xcode users can free up space on your Mac Howdy! Update Oct-19-2015: Updated for Xcode 7.0.1 (original post was for Xcode 5). First of all, this post is strictly for Xcode users.

The OS X operating system combines a stable core with advanced technologies to help you deliver world-class products on the Mac platform. Knowing what these technologies are, and how to use them, can help streamline your development process, while giving you access to key OS X features.

Apr 09, 2018 macOS Library Directory Details The Library directories are where the system and your code store all of their related data and resources. In macOS, this directory can contain many different subdirectories, most of which are created automatically by the system. Spoke to soon. I did not add the code back to the event. Still have the issue on IOS. I'm the user with the less internet speed, one of my friend downloaded iPhone Simulator in his Xcode 4.5 to test the code in iOS 5.1, 5.0, 4.3 os too, now if I want those simulators in my mac, is there any way from there I can copy those simulators and simply paste it somewhere in my XCode.app folder that I will get those simulators in my Xcode too? With the introduction of CoreSimulator in Xcode 6, each simulated device now has its own data. Previous versions had all devices share the same data for each version of iOS.

At a Glance

This guide introduces you to the range of possibilities for developing Mac software, describes the many technologies you can use for software development, and points you to sources of information about those technologies. It does not describe user-level system features or features that have no impact on software development.

OS X Has a Layered Architecture with Key Technologies in Each Layer

It’s helpful to view the implementation of OS X as a set of layers. The lower layers of the system provide the fundamental services on which all software relies. Subsequent layers contain more sophisticated services and technologies that build on (or complement) the layers below.

The lower the layer a technology is in, the more specialized are the services it provides. Generally, technologies in higher layers incorporate lower-level technologies to provide common app behaviors. A good rule of thumb is to use the highest-level programming interface that meets the goals of your app. Here is a brief summary of the layers of OS X.

The Cocoa (Application) layer includes technologies for building an app’s user interface, for responding to user events, and for managing app behavior.
The Media layer encompasses specialized technologies for playing, recording, and editing audiovisual media and for rendering and animating 2D and 3D graphics.
The Core Services layer contains many fundamental services and technologies that range from Automatic Reference Counting and low-level network communication to string manipulation and data formatting.
The Core OS layer defines programming interfaces that are related to hardware and networking, including interfaces for running high-performance computation tasks on a computer’s CPU and GPU.
The Kernel and Device Drivers layer consists of the Mach kernel environment, device drivers, BSD library functions (libSystem), and other low-level components. The layer includes support for file systems, networking, security, interprocess communication, programming languages, device drivers, and extensions to the kernel.

You Can Create Many Different Kinds of Software for Mac

Using the developer tools and system frameworks, you can develop a wide variety of software for Mac, including the following:

Apps. Apps help users accomplish tasks that range from creating content and managing data to connecting with others and having fun. OS X provides a wealth of system technologies such as app extensions and handoff, that you use to extend the capabilities of your apps and enhance the experience of your users.
Frameworks and libraries. Frameworks and libraries enable code sharing among apps.
Command-line tools and daemons. Command-line tools allow sophisticated users to manipulate data in the command-line environment of the Terminal app. Daemons typically run continuously and act as servers for processing client requests.
App plug-ins and loadable bundles. Plug-ins extend the capabilities of other apps; bundles contain code and resources that apps can dynamically load at runtime.
System plug-ins. System plug-ins, such as audio units, kernel extensions, I/O Kit device drivers, preference panes, Spotlight importers, and screen savers, extend the capabilities of the system.

When Porting a Cocoa Touch App, Be Aware of API Similarities and Differences

The technology stacks on which Cocoa and Cocoa Touch apps are based have many similarities. Some system frameworks are identical (or nearly identical) in each platform, including Foundation, Core Data, and AV Foundation. This commonality of API makes some migration tasks—for example, porting the data model of your Cocoa Touch app—easy.

Other migration tasks are more challenging because they depend on frameworks that reflect the differences between the platforms. For example, porting controller objects and revising the user interface are more demanding tasks because they depend on AppKit and UIKit, which are the primary app frameworks in the Cocoa and CocoaTouch layers, respectively.

Bring Your iPad App to Mac

Get a huge head start on creating a native Mac app based on your existing iPad app. Your Mac and iPad apps share the same project and source code, so any changes you make translate to both platforms. And your newly created Mac app runs natively, utilizing the same frameworks, resources, and even runtime environment as apps built just for Mac.

Sidecar

Apps on macOS Catalina automatically support an expanded workspace with iPad and Apple Pencil. Users can use iPad as a secondary display alongside Mac and draw with Apple Pencil on iPad. There’s no need to make any adjustments to your app — it just works. Apps can use Tablet Events in AppKit to enable full drawing tablet support, including pressure and tilt.

Machine Learning

With on-device model training and a gallery of curated models, there’s never been a better time to take advantage of machine learning. Core ML 3 seamlessly takes advantage of the CPU, GPU, and Neural Engine to provide maximum performance and efficiency, and lets you integrate the latest cutting-edge models into your apps. The new Create ML app lets you build, train, and deploy machine learning models with no machine learning expertise required.

AR Tools

Mac Os Library Developer Coresimulator 2017

Reality Composer is a powerful new app for iOS and Mac that makes it easy to create interactive augmented reality experiences with no prior 3D experience. Move seamlessly between your Mac, iPhone, and iPad as you build with live linking. RealityKit is a new high-level framework with photo-realistic rendering, camera effects, animations, physics, and more, built from the ground up specifically for augmented reality.

Metal

Metal gives the GPU even greater control of the pipeline, adds features that make it easier to perform advanced GPU processing, and simplifies the work you need to do to support different kinds of GPUs. New tools, including hardware-accelerated support in Simulator, help you get started faster and understand whether your app is using Metal correctly.

Accessibility

macOS Catalina introduces transformative Accessibility features that help users with disabilities get the most out of their Apple devices. All-new Voice Control lets users control their Mac and iOS devices entirely with their voice. And there are many exciting updates including new zoom features, VoiceOver enhancements, and color filters.

DriverKit

Mac Os Library Developer Coresimulator Version

The new DriverKit framework provides a fully modernized replacement for IOKit to create device drivers. Drivers built with DriverKit run in the user space, rather than as a kernel extension, for improved system security and stability.
