created swift programming language

This article focuses on the simultaneous use of swift and OBJECTIVE-C code in a project, and the simultaneous use of swift and objective-c mixed language programming in one project.Swift's compatibility with objective-c allows you to use both languages in the same project. You can use this feature called mix and match

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 Bo

Swift is a type-safe language, and the type-safe language requires a very clear type of value in the code. If you have a partial value in your code that requires a string type, you cannot pass int incorrectly. Given Swift's type safety, when compiling code, Swift performs type checking and marks any type mismatch as a

[Swift learning] Swift programming tour-character and string (5), swift tour String is the String type of swift. A string is a valid Character Sequence. Therefore, a character set can be expressed in combination. You can use the + symbol to connect to a string. String type

familiarize yourself with the swift syntax, You can use Swift quickly in the project. 3. Do iOS 8 and OS X Yosemite applications only use the swift language? No. Swift can interact smoothly with objective-C, and vice versa. Apple has not completely converted objective-C AP

After the swift language comes out, new projects may be developed directly using SWIFT, but some situations may occur in the process, some classes or encapsulated modules that have been written with OC, if you don't want to write it again in swift, you can use mixed encoding. This is allowed in ios8. First, it is simpl

, people use it because they have no choice in the long run and it makes sense. Wheeler said Swift quickly took him down and thought Apple would continue to patch objective C, "I wonder where it is now?" "Wheeler said. Language instincts Mainstream languages in the mainframe era had similar origins: Fortran from IBM, and COBOL was largely based on Grace Hopper's Flow-matic, which was

learn swift.Just take the time to familiarize yourself with the Swift syntax,Swift can be quickly used in the Project.3. IOS 8 and OS X Yosemite applications use only the Swift language?No. Swift language can interact smoothly wi

In the development of iOS apps, Swift will replace OC, the trend is "short-term coexistence, long-term replacement." But there have been too many code in the OC language, and Swift's development has inherited a lot of features from OC, and there are a lot of similarities. Swift and OC can now be seamlessly mixed-programming.I will implement a simple

A string is an ordered set of characters, such as "Hellow,world" or "Albatross." The strings in Swift are represented by string types and correspond to a collection of Character type values. The String type in Swift provides a high-speed, Unicode-compliant text-handling style for your programming. Swift's syntax for creating and processing strings is light and r

Integer An integer is an integer without a decimal number, such as 42,-23. Integers can be signed (positive, 0, negative), or unsigned (positive, 0). Swift provides a 8,16,32,64-bit form of signed and unsigned integers that follow a naming convention similar to the C language. The type of a 8-bit unsigned integer is the type of the uint8,32-bit signed integer, which, like other types of the

Learning Swift from scratch (Day 71) -- Data Type ing between Swift and C/C ++ Mixed ProgrammingFor Original Articles, please reprint them. Reprinted Please note: Guan Dongsheng's blog If necessary header files are introduced, the C data type can be used in Objective-C. C Data type cannot be directly used in Swift. Apple provides the data type that corresponds to

Google introduced the idea of go for the first time in 2009, and Facebook brought in hack last spring, and Apple released its swift language shortly thereafter.In war, winners write history books; in technology, winning companies are writing programming languages. Interconnection is built on the development of standards and code, but social networks and cloud com

Swift's compatibility with objective-c allows you to use both languages simultaneously in the same project. You can use this feature called mix and match to develop a hybrid-language application that can use the latest features of Swfit to implement a subset of the functionality of the application and seamlessly incorporate existing OBJECTIVE-C code. Mix and Match Overview Objective-c and Swift files can

Comments Use annotations to inject executable text into your own code as your own notes or hints. Comments are ignored when the Swift compiler runs. Swift's comments are very similar to the C language, with Single-line comments beginning with two backslashes: This is a line of comments Multiline comment begins with///ends with/*: See more highlights of this column: http://www.bianceng.cnhttp://www.b

As followsLet someresolution == Videomode ()Any class or struct instance created in this way will be initialized to the default value.　　Property accessUse point syntax to access the attributes contained in the instance. The syntax rule is that the instance name is followed by the property name, both by the dot number (.). Connection:println ("Thewidth of someresolution is

Since I'm talking about the hybrid programming of Swift and OC, my last blog, Swift and objective-c mixed programming--swift call OC, is about calling OC code in a swift project, and now we're going to implement calling
