Apple's new place of OC for a high-level programming language!
This lesson we try to develop a simple command-line games，To complete the experience a so-called "development process"。
This is a board game，We guess the location of enemy ships，As long as the number of hits you can send them to sink。
We give these ships the label affixed to point it ...... such a variety of sites?so，This has become a site of attack Behind his program ......。
We want players to[……]
Before we in class，Take a look at the previously mentioned "SoC" concept，We say this is called "Separation of Concerns"，I translate it as separation of duties - the different sections that focus on their part。Or a target to achieve a goal。
The goal not only to make the code more modular and easier to maintain，Also let the system run more efficiently。So，We want Object[……]
We use var to declare a variable，Congguizili like a tube placed in the experimental stage；
We give a specified variable type，Just like in the test tube labeled the；
Then put reagents must be marked on the label - otherwise could cause an explosion or poisoning。
Same，If we try to give a reservoir into a wrong data type，Then the compiler[……]
A lesson on our first taste OOP Style，Ambiguous classes and objects in exactly what is it? This lesson we use a simple little chestnut to introduce to you。
We say that the relationship between classes and objects and the relationship between the design of products，Take Our house is，Certainly there will be a corresponding building design，But the design will not only correspond to a building，At least one cell must be met with a design is not it? our[……]
Some students did not take into account the iPhone，Swift language learning but at least we will have OS X operating system，Our code shows will be completed in OS X，Using the CLI interface。So although it looks old and was，But believe me take the GUI make you worry a lot - because that is another matter。
We take a look，With O[……]
We all know that in Java declare an abstract class or method you want to use the abstract keyword，But unfortunately familiar things always gone，In Swift has no label。
Then，How should we declare an abstract class it?
It touches people very familiar, right? Bar private constructor of that class certainly can not be initialized[……]
Haha! And we met again，The ten milk to give us a newProgramming Course！
This is the syllabus before programming methodology，I was very glad to do so a decision to throw in outline here：) Although the end of the course，But a separate reading this outline is a good choice，I will go back based on this update it，To accommodate the new live version of the programming methodology -
The courses weAlreadyWith Karel[……]
Early in the 1970s，Stanford University graduate Rich Pattis think if we make the novice programmer in a relatively complex programming language,，Comparatively simple learning environment，Will contribute to the programming language teaching。This simple environment characterized by a variety of programming languages from abstraction。So he designed such a program environment，Allow students to teach a robot to solve simple problems。This robot is Karel[……]
Update it!
This update adds a branch，Goal is to create the "Next" function，In addition to repair the ugly side of the white block interface!
Currently no more modifications，run.swift file more refreshing，No more double thread it!
With an array of state of static storage Karel，Thanks for the banana king!
Adjust the speed of the great dream is within reach!?[……]
Swift provides a high-performance、Compatible with Unicode strings to achieve，It has also become a part of its own standard library。In Swift 2 in， String Type no longer comply with CollectionType protocol，Time [cray[……]
In Xcode 7 among，Playground allows us to use Markdown syntax similar to rich text format code has comments，Now，We will briefly explain how the text rich text notes。
Open your Xcode 7，In the Playground，Editor select the menu bar > Sh[……]
Today, a friend recommended an interesting page，A domain name is like：

In the Swift，All functions are closures，Standard functions are just the most complete closures name with parameters。
All right，The following is the text

Swift programming language learning time may not experience this thing，But with the depth of learning，As you read other people's code when，You will probably encounter this type NS，This time you will certainly be curious，similar String and NSString In the end where the difference? They seem to be exactly the same way! and，As by keyword，We can also easily make data transfer between both of them[……]
The original from InfoQ，Author Guo Lin。
Based on the Swift case study of language，Introduction what is a multi-paradigm programming language；Also introduces several of today's more popular programming paradigm，Worth a read。Collection，Original linkIn this。
Programming paradigm is the idea behind the program language。Representing programming language designers believe that how the program should be built and implemented。Common programming paradigm：[……]
WWDC conference in June this year on, Apple released Swift 2.0 Programming language。This new version has improved performance，The new API error control and detection support class availability。And improved Apple SDK platform API to make it more native to Swift。
For new features for，Also worth noting is that Apple will open later this year Swift[……]
We all know that in the Swift language which is no longer the main function，You may understand C language or Java language students arrived at this point of deep discomfort。In short，Instead main.swift。

Looks like this topic has been very fire Solarized，This is a terminal text color color scheme，Very nice，There are two kinds of light and shade，but，According to my own guess，Some more than it should be dark ......
Click below to jump to the official website。⬇️
Because the terminal is generally a little good-looking black😜
In short，The color theme for many terminals provides configuration files can be imported directly into，[……]
No matter what language you are learning，Will probably encounter a called MVC concept，It is a program development model，"Isolation and show" as the core，In the hierarchical framework has a great influence。
MVC Is a shorthand，Three uppercase letters corresponding to Model View and Controller 。
Now we create a application software，Many cases will bring[……]
In the C language which，To convert type does not seem to how difficult，The learning Swift when there is confusion。
Which of them seem to remember spoken tutorial，But remember，This has found，On record：
