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

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.

First of all, SWIFT is very popular. It ranks 16 in the month when it comes out. Why is it so hot? Is it because of the Apple brand? Or other reasons? As a code farmer (working for more than 15 years), I will talk about my personal opinions. There are many excellent PC-side development languages: JavaScript, Python, and Ruby. On the Mobile End, Java for Android is slow, and there is no freshness in addition. In iOS, objective-C is not slow, but the sy

What is the swift language? The following describes the swift programming language. Many of my friends are not familiar with swift because it is the latest programming language released by Apple on WWDC2014, let's take a look at the features of the language. Some people call Swift the best language. This is because ma

Swift 2.0 Exception HandlingWWDC 2015 announced the new Swift 2.0. This major update provides Swift with new exception handling methods. This article will be discussed mainly around this aspect.How do I build an exception type?In IOS development, we face a lot of exception handling. In Cocoa Touch we use Nserror for exception handling. In the new

An operator (operator) is a special symbol or phrase used to examine, change, or combine values. For example, the plus operator has two numbers added (such as let i = 1 + 2), and some more complex operators, such as logic and Operators () (e.g. if Entereddoorcode Passedretinascan) And the self-increasing operator (++i) (a convenient notation for the value of I plus 1). Swift supports most of the operators of standard C languages, and has improved so

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.

Swift identifier and keyword, swift identifier and Any computer language is inseparable from identifiers and keywords. The following describes the Swift identifiers and keywords in detail.
