What do you like best?
iOS SDK allows me to build apps for iOS. This is easy to use as well as easy to learn from others. It also has a simulator which helps me a lot. There are so many resources and tutorials for self-learning. So that developers can quickly solve any problem with this. Swift and Objective-C languages are supported.
What do you dislike?
Still is not fully compatible with new languages such as Swift.
What problems are you solving with the product? What benefits have you realized?
The iOS SDK is one of the most used software development kits. It also comes with many inbuilt features that help developers to build apps for the iOS operating system. The important thing here is that this allows us to work on Apple iOS while others won't allow it. I have been using iOS SDK for many years to build many iOS apps.
