Apple has made the switch from using static libraries to dynamic libraries, and has added this functionality to its programming language, which means it is developing faster than iOS itself. Developers can now easily submit their app along with the libraries they have written. Previously, it was necessary to wait for a new release of iOS, but now the situation has changed. Dynamic libraries provide the opportunity for more flexible improvements and changes to the code than ever before.

Swift is a more functional and accessible language that, like Objective-C, supports the official Cocoa and Cocoa Touch frameworks. There are many open source projects available online, including from major companies like Airbnb, which allow you to use all the modern techniques and solutions when writing code.
