SDK

Definition

A Software Development Kit (SDK) is a collection of software development tools in one installable package. They facilitate the creation of applications by having a compiler, debugger and sometimes a software framework.

Why It Matters

SDKs make developers' lives easier by providing pre-packaged tools, libraries, and documentation needed to build applications for a specific platform or service, such as iOS, Android, or a particular API.

Contextual Example

To build an app for an iPhone, developers use the iOS SDK, which includes the Swift programming language, simulators, and frameworks for accessing camera, location, and other device features.

Common Misunderstandings

• An SDK is more than just an API. An SDK often includes one or more APIs, but also contains other tools like debuggers and code samples.
• You don't always need an SDK to use an API. Sometimes, you can make direct HTTP requests to an API without a specific kit.
