Back in 2014, when apple revealed the brand new Swift programming language, it did not perform as well as expected. However, it picked up the pace in later years and now it is the primary language for app development. If you create app like SC for iPhone, then you can be sure that you will have to use swift. That is because of the fact that swift does not only cut the development time short, it is also great for developing applications with modern design & UI. Did you find this useful?
