On the other hand, if you are familiar with C, C#, C++, or other languages of C, then you may find the learning curve of iOS development easier.
One thing to note here is that if you are familiar with any programming language, especially the Object-oriented ones and know how object-oriented languages work, learning to develop either iOS or Android apps should not be a problem. However, it’s a completely different story if you have zero knowledge of coding.
