Cocoa is Apple's native object-oriented application programming interface (API) for its desktop operating system macOS.
A computing platform or digital platform is the environment in which a piece of software is executed. It may be the hardware or the operating system (OS), even a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed with it. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.
The iPod Touch is a line of iOS-based mobile devices designed and marketed by Apple Inc. with a touchscreen-controlled user interface. As with other iPod models, it can be used as a music player and a handheld gaming device, but it can also be used as a digital camera, a web browser and for messaging. It is similar in design to the iPhone, and it connects to the Internet only through Wi-Fi and does not use cellular network data, thus it is not a smartphone. As of May 2013, 100 million iPod Touch units had been sold since 2007.
A mobile operating system is an operating system for mobile phones, tablets, smartwatches, 2-in-1 PCs, smart speaker, or other mobile devices. While computers such as typical laptops are 'mobile', the operating systems used on them are generally not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This distinction is becoming blurred in some newer operating systems that are hybrids made for both uses.
iOS is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that powers many of the company's mobile devices, including the iPhone and iPod Touch; the term also included the versions running on iPads until the name iPadOS was introduced with version 13 in 2019. It is the world's second-most widely installed mobile operating system, after Android. It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. It is proprietary software, although some parts of it are open source under the Apple Public Source License and other licenses.
Cocoa Touch is the application development environment for building software programs to run on iOS for the iPhone and iPod Touch, iPadOS for the iPad, watchOS for the Apple Watch, and tvOS for the fourth-generation Apple TV, from Apple Inc.
The iOS SDK, formerly the iPhone SDK, is a software development kit (SDK) developed by Apple Inc. The kit allows for the development of mobile apps on Apple's iOS operating system.
The version history of the mobile operating system iOS, developed by Apple Inc., began with the release of iPhone OS 1 for the original iPhone on June 29, 2007. Since its initial release, it has been used as the operating system for iPhone, iPad, iPod Touch, and HomePod, seeing continuous development since then, resulting in new major releases of the software typically being announced at the annual Apple Worldwide Developers Conference and later released in September, coinciding with the release of new iPhone models. The latest stable versions, iOS 14.2 and iOS 14.2.1, were released on November 5, 2020 and November 19, 2020, respectively; iOS 14.2.1 was released only for iPhone 12 and iPhone 12 Pro models. The latest beta version, iOS 14.3 beta 3, was released on December 2, 2020.
Jailbreaking refers to privilege escalation on an Apple device to remove software restrictions imposed by Apple on iOS, iPadOS, tvOS, watchOS, bridgeOS and audioOS operating systems. Typically it is done through a series of kernel patches. A jailbroken device permits root access within the operating system and provides the opportunity to install software not available through the iOS App Store. Different devices and versions are exploited with a variety of tools. Apple views jailbreaking as a violation of the End-user licence agreement, and strongly cautions device owners from attempting to achieve root access through exploitation of vulnerabilities.
webOS, also known as LG webOS and previously known as Open webOS,HP webOS and Palm webOS, is a Linux kernel-based multitasking operating system for smart devices such as smart TVs that has also been used as a mobile operating system. Initially developed by Palm, Inc., HP made the platform open source, at which point it became Open webOS.
FaceTime is a proprietary videotelephony product developed by Apple Inc.

Force Touch is a technology developed by Apple Inc. that enables trackpads and touchscreens to distinguish between various levels of force being applied to their surfaces. It uses pressure sensors to add another method of input to Apple's devices. The technology was first unveiled on September 9, 2014, during the introduction of Apple Watch. Starting with the Apple Watch, Force Touch has been incorporated into many products within Apple's lineup. This notably includes MacBooks and the Magic Trackpad 2. The technology is known as 3D Touch on the iPhone models. The technology brings usability enhancements to the software by offering a third dimension to accept input. Accessing shortcuts, previewing details, drawing art and system wide features enable users to additionally interact with the displayed content by applying force on the input surface.
The sixth-generation iPod Touch (stylized and marketed as the iPod touch, and colloquially known as the iPod touch 6G, iPod touch 6, iPod touch or iPod 6, is a multipurpose handheld device designed and marketed by Apple Inc. with a touchscreen-based user interface.

The iOS mobile operating system developed by Apple Inc. has had a wide range of bugs and security issues discovered throughout its lifespan, ranging from security exploits discovered in most versions of the operating system related to the practice of jailbreaking, as well as bypassing the user's lock screen, to issues relating to battery drain, to crash bugs encountered when sending photos or certain Unicode characters via text messages sent through the Messages application, and general bugs and security issues later fixed in newer versions of the operating system.
