About this article:1, explain the purpose of this article writing2. The basic syntax tree of Swift is collated3, look at the picture compositionI. Purpose of writingYesterday read a knowledge column, the author is about "How to study learning." The whole course 1个小时9分钟, it cost me 19 yuan. There is one point of view that I like very much. That is, "to learn new knowledge as a study." So I'm going to put it into action today and learn how to study

Basic operators of Swift, Swift Operators Today, I learned the most basic knowledge about Swift language. Here are some of my understandings and conclusions. I hope to help more people understand the area. If anything is wrong, I hope you can point out that, so that timely correction can be made. 　　 　　Basic Operators An operator is a special symbol or phrase that

1.Introduction to SwiftThe new development language, released by WWDC in 2014, works with OC on Mac OS and IOS platforms to build apps based on Apple platforms.After the swift2.0, the syntax was stable, and the swift4.0, released in 2017, changed, but only added some new features. These new features need to be run on Xcode9 to show the effect. It is worth mentioning that it supports UNICODE9, which means that you can use some image icons to act as variables.2. Features :① is fast , secure , us

Welcome to SwiftCurated to: iOS enthusiast, titleI try to use my spare time to translate Apple official documents, limited to the level, inevitably wrong, welcome to correct me.June 3, 2014Recommendation Number: 123-4567About Swift (Swift)Swift is a new development language for iOS and OS X applications, built on OC (OBJECT-C) and C, but without the limitations o

Readonly,readwrie directly by declaring a variable Var, declaring a constant let to indicate Copy is declared through the @nscopying directive. It is important to note that String,array and dictionary appear

When I first saw the swift extension, I thought about the extensions and categories of OC, so I was looking for Swift's expansion and OC extensions and categories. After several searches, the expansion of swift and the category of OC were found to be the same. But I'm a little more than a piece of the way to find out what it is like for the OC extension of Swift.

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 simple to start with, first study the mixed use in

Interoperability is a feature that enables swift and objective-c to be interfaced, enabling you to access and use code written in another language in a file written in one language. When you are ready to start incorporating swift into your development process, you should know how to use interoperability toInitialize (initialization) in order to instantiate the Objective-c class with

Swift uses closure expressions and swift expressionsThe closure expressions in Swift are flexible. The standard syntax format is as follows:{(Parameter list)-> return value type inStatement Group}The parameter list is the same as the parameter list in the function. The return value type is similar to the return value type in the function, but the difference is th

Swift up and running--integers and floating-point numbersThe original study of the parkParking Learning Techniques VideoIn Swift , numbers are divided into integers (for example: 1/10/100/1000, etc.) and floating-point number (for example: 3.14/1.44/2.71, etc.). Let's look at integers first. Integers-Int UIntAccording to the content space (8/16/32/64-bit) occupied by an integer variable and whether t

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 swift call OC

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 Swift code in the OC project, is also very convenient.
