In Swift, you can directly use the APIS provided by Objective-C language (including the system framework and custom code), and use the classes and APIs provided by Swift in Objective-C, it can also use both Swift and Objective-C languages in a single project. The two languages can interwork and interact with each other. Any Objective-C framework or C library (inc

Swift provides a C-like process control structure that includes a for and while loops that can perform tasks multiple times, select if and switch statements that execute different branches of code based on specific criteria, as well as break and continue statements that control the flow to other code.In addition to the traditional for conditional increment loop in C, Swift also adds a for-in loop to make it

Dictionaries (dictionary)A dictionary is like a container that can hold a number of values of the same type. Each value has a unique key associated with it, and the key in the dictionary acts as if it were an identity card for each value. Unlike elements in an array, each element in the dictionary does not have a fixed sequence. When you use a dictionary and you want to query a value, You need to use the value's identity (key). It's like you use a dictionary in your life to find the definition o

A class can inherit (inherit) and has a class method, property, and other features. When a class inherits other classes, the inherited class is called subclass, And the inherited class is called superclass (or parent class, superclass ).

As the name implies, when we look up a dictionary, we look at the resources we need to find based on the index, and in Swift, every object in the dictionary contains a key and a value, and we use key to find the value corresponding to the current key. Unlike arrays, data items in a dictionary do not have a specific storage order in the dictionary.Similar to the array in swift, the
