Swift provides three main collection types: array, set, and dictionary. This section describes array.
An array is a set of the same type of storage order. The same value can appear in different positions multiple times.

The concept of generics also exists in Java. Generics can make code more refined and are an optimization for data types. Now there is the same requirement: Write a struct, and then judge whether the integer is equal. The implementation code and output are as follows:

Migration processes (the migration process)
Problem solving tips (troubleshooting tips and Reminders)
Migration provides an opportunity to revisit existing objective-c applications and to better optimize the architecture, logic, and performance of the application by replacing some of the swift code. In
This series of articles focuses on learning and researching OpenStack Swift, including environment building, principles, architecture, monitoring, and performance.(1) OpenStack + Three-node Swift cluster + HAProxy + UCARP installation and configuration(2) Swift Principles and architecture(3) Swift monitoring(4)
Migration provides an opportunity to re-examine existing objective-c applications, as well as the Swift code to better optimize the architecture, logic, and performance of your application. Directly, you will use the previously learned mix and match and the interoperability between the two languages for incremental migration work. The Mix-and-match feature makes it easy to choose which features and functions to use with

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

Translator's nonsense:
I stayed up late a few hours ago and watched WWDC. I was so excited that this year was very promising! When Swift came out, it was a dumb to learn a new language. This article is from Apple's official book "The Swift Programming Language", which is about 500
Sometimes, it may take some time to read English documents. If you read Chinese documents, you may be afraid of inaccurate translation. In some cases, you do not need to write any word. If the translation is inaccurate, ambiguity may occur, so let's take a look at Swift in this way.Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C, without the constraints of C compatibility.
Basic Swift data type, swift data typeConstants and variables
Constants and variables are represented by a specific name, such as maximumNumberOfLoginAttempt or welcomeMessage. A constant points to a specific type of value, such as a number of 10 or the character "hello ". The value of a variable can be modified as needed, but the value of a constant cannot be changed twice.Declaration of constants and vari
