A specific format enables applications on the iOS platform to communicate with each other and respond to requests initiated by other apps or web pages. It functions as a unique identifier, allowing one application to open another and, optionally, pass data or commands. For example, a mapping application could be launched directly from a website by specifying a particular identifier within a hyperlink.
This inter-application communication mechanism is fundamental to the iOS ecosystem, providing a seamless user experience by allowing applications to work together. Historically, its adoption facilitated deeper integration between apps, enhancing functionality and user workflows. The consistent application of this addressing system allows developers to offer cross-application functionality, driving user engagement and promoting a more connected digital environment.
