Being an app developer is a pleasant and challenging profession that requires extensive computer knowledge. If it is for the Apple operating system, they must be able to respond to the needs of the open-source Swift language that was developed by “Chris Lattner” in July 2010 with the final collaboration of many other developers at Apple. The Swift language took ideas from Objective-C, Rust, Haskell, Ruby, Python, C, and many other languages to build its frontend for creating an app for WatchOS, iPhone, iPad, MacOS, TvOS, and also can use databases such as MongoDB or RealM for the backend. Android also created a program called Android Studio to expand applications related to Android operating systems. In addition to all of this, in 2017 Google created an open-source software development kit called Flutter for Android, IOS, Microsoft Windows, MacOS, Linux, Google Fuchsia, and Web platforms. Creating an application that is compatible with IOS or other operating systems is a very pleasant and useful task
