How To Make iPhone Apps – An XCode 5

1. Where Can You Download XCode? The easiest way to get XCode is through the Mac App Store Click the

link to go to the listing.

You can also download it manually if you don’t have the Mac App Store. Just visit the Apple Developer Page for Xcode.

How To Make iPhone Apps – An XCode 5


2. Demystifying The XCode InterfaceThe diagram below is from the Apple Documentation for Xcode.If your interface looks different, make sure you have XCode 5 and not an earlier version.

The reason this is a great diagram is because it lets me refer to these different sections of the interface and you can refer back to this diagram to see what I’m talking about.

As you can see from the diagram, there are 4 major areas: the Navigator, Editor, Debug Area and Utility Area.

Keep in mind that you can adjust the size of each of those panes by hovering your cursor over the boundaries of each area and dragging.

Project Navigator

◦ This is where you’ll see all the files associated with your project.


3. The Navigator Area


You can also right click on the project navigator and create new files or add existing files to your project. Or you can drag folders or files from your computer directly onto the project navigator and will popup a dialog asking how you want to add the files.

If you click on a file in the project navigator, it will display the file’s contents in the Editor area. If you double click a file instead, it will open a new window which can be useful when you have dual monitors.

Search Navigator

With the search navigator tab, you can easily look for pieces of text in your project.

Issue Navigator

The issue navigator shows you all the problems with your app.

The editor area is where we’ll probably be spending most of our time! This

is where all the coding happens.


3. The Editor Area


Navigation within the editor areaThere are these little back and forward arrows in the upper left corner of the editor area. Unfortunately these arrows aren’t labeled in the trusty XCode interface diagram at the beginning of this article so I’ll call them “XCode back and forward arrows” and show you an image of them here:

These guys are actually pretty useful. They act like the back and forward buttons on your browser and they let you navigate to previously viewed files.

Three types of editor views

The editor area has three different views and you can toggle between them with the set of buttons in the upper right hand corner:


Interface Builder ViewSo far we’ve been talking about editing code files and writing code, however XCode has interface builder integrated in and when you’re viewing the Storyboard or a XIB file, the editor area will turn into a visual designer.

Finding and replacing within the fileJust hit Command-F to bring up a search popup in the upper right corner that will look for whatever you type in within the current file. This is also a great way to jump to various areas of your file. You can also use this popup to do replacements within your file.

Jumping to definitionsIf you’re looking at some code and you see a classname that you want to jump to the definition of, you can hold down Command and click the classname to quickly jump to that file.

The XCode utility area is comprised of two panes: the inspector pane and the library pane.


4. The Utility Area


Inspector pane

The Inspector pane will give you details about the file you’ve got highlighted in your project navigator. However, when you’re looking at a XIB file, the inspector pane will show you the different attributes that you can modify for a selected element.

library pane

The library pane won’t be very useful either until you’re looking at a XIB file. When you’re using the Interface Builder part of XCode, you can drag UI elements from the library pane onto the editor area to add that element to your user interface.

The debug area will show you console output and the state of various variables when you run your application.

You’ll be using this a lot while debugging your code and trying to figure out why things aren’t working out the way you expect them to! I’ll need to write a separate XCode debugger tutorial because there’s too much to mention here.


5. The Debug Area

We’ve talked about some of the buttons on this tool bar already. Let’s start from the left.

The left-most button is the run button. This will build and run your application and launch your app in the iOS Simulator. The button beside it will stop the execution of your application and return you to XCode.

If you click and hold down the Run button, you’ll get more options to run your app.


6. The Toolbar

The Organizer button on the far right of the toolbar brings up a separate window called the Organizer. There are several different purposes of the organizer and we’ll highlight them below.

Devices There are a lot of things you can do in the devices tab that I can list them

all. However, the main uses are to manage your provisioning profiles on your system AND on various devices.


7. The XCode Organizer

We haven’t talked about provisioning profiles yet, but they’re important for deploying your app on actual physical iOS devices. I’ll need to create a separate tutorial for that.

You can look at crash log from devices, enable development use for various connected devices and more.

Repositories

This only applies to XCode 4.In XCode 5, Repositories are now managed in XCode->Preferences->Accounts

In the repositories tab, you’ll be able to manage local and remote repos that you have set up for your projects.


ProjectsIn the projects tab, you can see a list of projects you’ve opened before so you can quickly open them again and you’ll be able to manage derived data and snapshots of your projects as well.

ArchivesIn the archives tab, you can manage your archives for various projects. You would archive your app when you want to deploy it to the store or distribute it in some other manner.

Documentation

This is only for XCode 4.In XCode 5, Repositories are now managed in XCode->Preferences->Downloads

You can view various iOS SDK



7. The iOS Simulator


XCode 5 comes bundled with a wonderful iOS Simulator for you to test your application on. In fact, you can use the iOS simulator for most of your development and then find a device to test on when you’re nearly done.

You can actually do a lot with the simulator including:

-Device rotation-Simulating various GPS coordinates-Device shake-Simulating low memory scenarios

If you want to test various network or low bandwidth conditions, there’s a tool called Charles Proxy that works brilliantly.
