What version of Xcode is needed for development for iOS 8?

Need xcode 6 or later. The possibilities of integration with Apple Watch in version 6.2, which is currently in beta testing, have significantly expanded.

[mfilonen2]

What is Swift?

Swift is Apple's new object-oriented language, a replacement for Objective-C and used (starting with iOS 8) to write applications for Apple's mobile operating systems.
Innovations and features of the language are as follows:

• New types of variables and arrays (tuples).
  
• Significant simplification of the syntax: a decrease in the volume of long names, it is not necessary to put; after each line, multiline comments are allowed next to the code to improve the comprehensibility of the program.
  
• Similarity to scripting languages: reducing the amount of code, making it easier for web developers to program in Swift.
  
• Sandboxes (PlayGrounds), where you can create variants of a particular code and observe the result of the change, without changing the source code or compiling the program again.
  
• Reducing the number of associated files, and, ka result, the amount of memory occupied by the application.

[mfilonen2]

A bit about WatchKit

The main feature of the watch is that the already compiled code that is stored on the iPhone is transferred to them. THAT is, in fact, without the Apple Watch iPhone can not work. The code and data are transmitted via Bluetouth, while only interface files and some other data are stored on the clock.
There are 3 types of applications for Apple Watch:

• Glance. The simplest application that does not provide user interaction from the interface will be used to display static information.
  
• Notification. Notifications are of two types - simple (which do not have buttons) and more advanced, with buttons and other interface elements, for example, to go to the appropriate application.
  
• Watch App. Full application for Watch, where all interface elements are used.

Elements that can be used in the clock interface:

• Button
  
• Label slider
  
• Image
  
• Separator
  
• Switch
  
• Date
  
• Map
  
• Menu
  
• Table

At the same time, since the code is executed on iOS, developers, with the exception of demanding tasks, all types of methods and functions from iOS 8 are available.
There are 2 main application files:

• InterfaceController.m is an application interface controller that runs on an iPhone.
  
• Interface.storyboard - application interface file stored on Apple Watch.

Accordingly, WatchKit itself links these 2 files into a single application.

Application Empowerment

In iOS 8, developers have received a new APi to expand the capabilities of their applications. Now they can use the Touch ID fingerprint scanner, previously used only to unlock and enter the iTunes Store. Also now, developers can integrate their items in the "Actions" and "Share" menus (which is relevant for both social networks and various extensions (translators, programs for storing passwords, etc.).
The user can swap items in this menu.
Also, applications can now exchange data, and the integration of third-party applications into the system has become deeper than before. At the same time, each program, as well as in other mobile OS, is located in its sandbox, which ensures the security of the system.

IOS Terminology and Tips.

Xcode - this is an integrated development environment fromApple (IDE) .
iOS SDK - iOS development kit released in March 2009 by Apple. iOS SDK Available for Mac OS X only .
Mac OS (Macintosh Operating System) - Apple’s proprietary operating system family.
Objective-c - a compiled object-oriented programming language used by Apple.
Ad hoc - a way to distribute applications without the AppStore, by directly installing the application build file through iTunes.

We now turn directly to the tips and instructions.

So,first instructionand included in it - advice:

Registration in the iOS Developer Program.

You have two options:

• iOS Developer Program- $ 99 per year
  
• iOS Enterprise Developer Program

The difference between them is as follows: when you participate in an Enterprise program, you cannot, unlike a regular program, upload your applications in the AppStore, but you can develop in-house applications — applications for internal use in your company without open access. If you decide to develop an in-house application for your customers, then they are encouraged to join this program. The iOS Developer Enterprise Program Support Center explains this question (the last question on the list)

Otherwise, the programs provide the same features:

• access to development tools and SDK (including beta versions);
  
• access to the Apple Developers Forums;
  
• access to learning resources (example programs, articles, videos);
  
• the ability to use Ad Hoc to distribute applications;
  
• the ability to test your applications on iPad, iPhone, iPod-touch;
  
• opportunity to receive technical support.
  

Is Mac Required When Developing?

Youwill definitely need Mac OS X , because on any other platform you will not be able to work with the iOS SDK. There are many different options for developing iOS applications, but you will need Mac OS X to build and load the application in the AppStore.

Ways to get Mac OS X:

• buy a mac (obviously)
  
• hackintosh.com
  
• virtual machine

Mac mini Now it is quite an accessible thing, although, of course, you always want more, and there prices at Apple are already beginning to bite.
Regarding the other two options: I heard feedback from people who are quite happy with the hackintosh or with Mac OS X on VMWare, but I also have enough accumulated negative experience. It all depends on the iron, straightforward hands and your desire.
In general, if you want to develop for iPhone, the operating system should not be an obstacle.

Tools you can use for development.

Here I will touch on only a few tools - after Apple removes the ban on non-native development tools, almost every day new IDEs and frameworks appear.

Native development tools:

It is primarily a language.Objective-c and development environment Xcode (for company with Interface builder , iPhone simulator and other applications from the developer’s package). You can also write to C and C ++ , but without Objective-c you in some moments will still not do.

Xamarin iOS - allows you to develop applications for iDevice on C #. A noticeable minus for .NET developers is the price - $ 399 for an individual license.

About Objective-C

Objective-C has built a very large class hierarchy. If you go down from the most specific (from the same UIButton button), down to the more general, then at the very bottom we will meet with the base class, which is called NSObject.
Any class is inherited from it.

So, let's begin.

1. To create a class, right-click on the group into which you want to place it and select New File:
   
   Screen

   
   
   
2. Choosing the Cocoa Touch - Objective-C class:
   
   Screen
   
   
3. Enter the name, I chose "MyClass", in the Subclass of line (which class heir) select NSObject - we will inherit from the base class itself.
   
   Screen
   
   
4. Select a folder to save the file and it appears with us:
   
   Screen

   

Now for the .h and .m files.

The file myclass.h is called the header file (header, heder) - it contains information about the class, namely its list of properties and methods available to other classes.
Here it contains the following lines:

#import<Foundation / Foundation.h>

@interface MyClass: NSObject

@end

This is the base class declaration. The first line means that we import Foundation classes — in fact, all of the main Objective-C classes are strings, numbers, etc. contained there.

Next, we declare the interface — that is, the list of available methods and properties of our class — with the @interface keyword and write the name of the class MyClass, and after the colon, the name of the class from which we inherit.

@end as it is not difficult to guess, completes the description of the interface.
Let's do something simple. For example, let our class have a "description" property, in which we will store its text description + it will have the "say hello" method, which will display the message "Hello, World!" To the console.

Add a description of the method and properties to the interface:

#import<Foundation / Foundation.h>

@interface MyClass: NSObject

- (void) sayHi;
@property (nonatomic, retain) NSString * myText;

@end

We first declared the sayHi method, which will print the messageHello, world .

Let me remind you that since it does not accept any parameters, there are no colons in it. And, since it does not return any data, we write- (void) before the start of the method.

Next comes the property declaration.
For now, we will not analyze it in detail - suffice it to say that we have an object of the class string (NSString) to which the pointer namedmyText .


Let's take a look at MyClass.m:

#import "MyClass.h"

@implementation MyClass

@end

The first line indicates the class description in the header.
And then we write@implementation , to show that there will be a code of methods.

Change it to look like this:

#import "MyClass.h"
@implementation MyClass
[B] @synthesize myText [/ B];
- (void) sayHi
{
NSLog (@ "Hello, world!");
}
@end

About@synthesize we are not going to talk yet, except to briefly say - instead of us, it generates code that will allow other objects to “read” the contents of the string myText and install it.

Then we write the sayHi method, very simple and straightforward :) It simply prints text to the console with the NSLog command.

Let's now add a button to our form and assign the askForHi method to it.
How to add a new method to ViewController, you should know from the old lessons - so add it so that it looks like this (from -

(IBAction) askHi: (id) sender
{

}

And do not forget to tie it to the button!

At the very top of ViewController.m, add the line:

#import "MyClass.h"

This line will tell the ViewController class that there is a class MyClass.
Now back to our method:

- (IBAction) askHi: (id) sender
{
MyClass * obj = [[MyClass alloc] init];
[obj sayHi];
obj.myText = @ "Some text";
}

The first line creates an object of class MyClass. On the creation of the object - in the following lessons, for a start we will know that the object is created that way.
Then we call the sayHi method, and in the third line we write the text into the string.

Now, if you start the application and click on the button, then in the console you will get the lineHello, world :

Screen

Creating a certificate signing request

To obtain a design certificate, you need to create a certificate signing request (CSR). Create a CSR with the utilityKeychain AccessatOS X . The utility is searched in the folder Utilities (Utilities) в†’ Applications (Applications). Open the menu Keychain Access, select Certificate Assistant , further indicate the option "Request a Certificate From a Certificate Authority" . Fill out the form where we enter your name and email address that you provided in the account of the Apple developer. We leave the email field of the authorization certificate empty, and do not forget to select the option "Saved to disk" , to save the certificate signing request to your system. Do not put a selection on the checkbox under the label "Let me specify key pair information" .



We press"Continue" , and specify the location of your CSR, then press the button "Save" . Check the folder you specified to see if the CSR was created. In Keychain Access, in the Keys category, we see public and private keys that have been added to your key chain for authorization.




Create a development certificate

We return to the iOS Provisioning Portal, and select the Certificates tab. Click on the “Request Certificate” and download the CSR that we generated in the previous step. We note that the status of the new certificate is set to Pending Issuance. After several updates of the page, the status should change to the issued, the download button should also appear on the right side. Click on the download button to download your new certificate of iOS development.TwiceClick on the certificate to add it to your authorization key chain.

Screenshots for instructions

Adding keys

Add iOS device

For you need to specify the devices on which your iOS application will run, adding the device to the iOS Provisioning Portal. We will review the iOS Provisioning Portal by clicking on the “Devices” tab, then click on the “Add Devices” button. To add a device, enter a descriptive device name and device ID.Device ID (also known as UDID) is an identifier that uniquely identifies an iOS device. Note that UDID is not the same as the serial number.



Find the UDID of the device by connecting it to the computer and running Organizer (Organizer) in Xcode. You can also open the organizer by choosing Window from the Xcode menu and then Organizer. Select the “Devices” tab at the top, then select the device you are interested in. Next you will be given a 40-character string next to the Identifier label - this will be the required UDID.

Frameworks

Any iOS application is created using Objective-C and frameworks. The frameworks developed by Apple include a library of functions that your application accesses. At the same time, several applications can have access to the framework library at once at the same time.

Apple creates frameworks that already contain all the necessary functions, which saves time and is a kind of guarantee of the quality of the work done.

Development tools for iOS 8.x.x

• Mogenerator
  In short: when you re-core the Core Data Entity, all changes are erased. Mogenerator separates generated from dataset. Judging by the reviews in the tracker, Swift 1.2 works fine.
  
• Swift Bootstrap
  Web service to simplify the selection of colors, creating screenshots of the application and training screens. Implementation, admit, not too interesting. The idea to create code based on the results of filling out a web form is more interesting.
  
• Bitrise
  CI for iOS in the cloud. First of all, there are not so many of them. Secondly, it has a free rate.

For codes

• Introducing Parse Push for OS X
  Nikita Lutsenko from Parse reports that the ability to send push notifications to OS X has been added to the SDK.
  
• Gaugekit
  Scales for displaying information, written in Swift, supported by @IBDesignable and @IBInspectable, lives in the form of a hearth. Take a look at the pictures in the readme.
  
• Valet
  A wrapper around Keychain for iOS and OS X. Before that, I used SSKeychain, but here's a young punk.
