How do I use Swift for network requests?We first create a swift project, the project name is SwiftdemoThen create a new OC class in the project, and Xcode will ask if you are creating a Swiftdemo-bridging-header.h file that bridges OC and SwiftSelect Yes to generate the project name-bridging-header.h file, in which we introduce the OC framework corresponding to the header file can be implemented in the

First, IntroductionAs Swift matures, the use of swift development or hybrid development has become a trend, and Apple is recommending the use of Swift as a new language. Swift has now been updated to 3.0, and it is estimated that no more than 4.0 will come out. Then there are some unavoidable problems when developing w

By using a single line of code to do the same 10 exercises, let's take a look at the battle between Swift and other languages.　　Multiplies the value of each element in the array by 2Use map to implement var arr = [1,2,3,4]; var newArr = arr.map{$0*2} for item in NEWARR { print (item) }The code completes the array element by 2 simply and clearlyTo find a set of numbers andThis problem can be solved by using

Swift Programming Language-how to use Inheritance in Swift, swiftlanguage One class can inherit the methods, properties, and other features of the other class. When a class inherits other classes, the inherited class is called subclass, And the inherited class is called superclass (or parent class, superclass ). In Swift, inheritance is a basic feature that disti

[Ridicule Apple] the Swift language is the best language that is only second only to PHP. without such a second language, it makes up for the shortcomings of PHP. Of course, Swift can also do

"Objective-C" in the Language. Other projects can input content based on their actual conditions. After setting related project options, click "Next". The subsequent steps are similar. As shown in the figure below, a main. m file is generated in the left-side navigation pane. Open the main. m file and you can see its code in the Code interface on the right.

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 to develop a mixed-language application that can implement part of the app's functionality with the latest features of Swfit and seamlessly incorporate into existing objective-c code.Mix and Match OverviewObjective-c and Swift files can coexist in a project, whether the project was originally based on objective-c o

[Swift] learning notes (1) -- getting started with basic data types, code styles, tuples, assertions, and swift learning notes Since Apple released swift, I have been trying to learn about it and have never been fully involved in it. From today on, I will use blogs to drive my swift learning, it is also faster for ever

Hybrid programming in Apple system development (2): mutual calls between Swift and C, system development swiftWhen performing mutual calls between Swift and C, it is necessary to first understand the type conversion relationship between the two languages: C type Swift type Bool CBool Char, signed char CChar Unsigned ch

Navigation Bar BasicsThe navigation bar (NavBar) and the Navigation (NAV) described in the previous section have a different word and a "bar". In fact, in the bootstrap framework they are still the obvious difference. There is a background color in the navigation bar (NavBar), and the

type values.Generic typeTypically in generic functions, Swift allows you to define your own generic type. These custom classes, structs, and Enumerations Act on any type, as is the use of array and dictionary.This section shows you how to write a generic set-type –stack (stack). A stack is a collection of a range of ranges, similar to an array, but it is a more restrictive collection than the array type of Swift
