Let's say the addition operator + can speak two numbers together.Other complex examples are logic and or self-increment + +. Swift supports most of the operators in C, and adds some enhanced features to reduce errors in the code. The assignment Budget character = does not return a value.
Swift is a new programming language for the development of IOS and OS X applications, however, its development experience has much in common with C or objective-c.
Swift provides all the underlying types in C and objective-c, including int representing integers, Double and float for floating-point numbers, bool for Boolean values, and String that represents plain text data.

At this time, everyone is standing at the same starting line, and the Swift language will be the next popular programming language in the programmer field. It is close at hand to seize the lead.
We recommend a video tutorial on the Swift programming language in this issue, including: basic use of the development environment, data types and constants, automatic data check and inference, definition and use of
The Swift language uses VAR to define variables, but unlike other languages, Swift does not automatically assign an initial value to a variable, which means that the variable does not have a default value, so it must be initialized before it is required to use the variable. If you do not initialize before using the variable, you will get an error: var stringvalue:string//error:variable ' stringvalue ' use

Apple released a new Swift programming language for developing iOS and OS X applications. Its purpose is self-evident: To give old Objective-C a suitable successor! Therefore, it is not hard to predict that the next 10 years will inevitably be an age of
Swift struct and class, Swift structIn a process-oriented programming language (such as C language), struct is used a lot, but after object-oriented, such as in C ++ and Objective-C, struct is rarely used. This is because struct can do things, and classes can be replaced completely.The Swift language attaches great importance to struct and uses struct as an impor
