SWIFT cooperates with international organizations for defining standards for message format and content and is also Registration authority (RA) for ISO standards.

Swift has total interoperability with existing Objective-C programming language. Swift code can even co-exists alongside existing Objective-C files in the same project, with full access to Objective-C API.
It’s a modern and safety language, with an advanced error handling model, easy syntax, and is intended to become open source sooner.
