Have fun discovering! Ever wonder how that Great Apps was created, or how they created that cool mobile games? Or maybe you just want to know how to do some really awesome stuff in Xcode8. Well, then, this app is for you! Contact us] Email:tapinfinity gmail.
This app has been updated by Apple to display the Apple Watch app icon. Optimizations for the user experience 2. Bug fixes. The app is very easy to utilize and follow instructions on guided steps on how to use iOS coding for Apple software. I found it very informative and and was humored.. It fails to allow an opportunity to use or apply the skills in tutorials. Graphics and steps okay but no utilization available. The developer, Li Fazhan , has not provided details about its privacy practices and handling of data to Apple.
The developer will be required to provide privacy details when they submit their next app update. I suppose its adequate to make use of some of your concepts!! Chris, I am new to this Xcode stuff and I have searched and searched for the answer I hope you can help. Thanks in advance. Hello chris.. Hi Chris, you have been asked this many times already, but do you have a quick resorce guide pdf that i can reference to?
Chirs, Do you have PDF of these files. Please mail me auminfotechin gmail. You were really close! How can i make sure it works perfectaly?? Do you know why? Maybe the simulator is too large? Try a different zoom level.
Otherwise I think the tutorial is fantastic thus far!! This was a great guide! One thing though, when I click the run button, it only shows the bottom of the screen. Do you think you could help? Hi Chris, I want to learn how to develop iphone apps.
Basically like a normal weblink but for xcode. I am completely new to this…any help is appreciated. Nearby, I have found your tutorial, when I was looking for a hint to where the nice popup for filtering objects by sections formerly placed nearby the objects tab in Xcode 4 is gone in Xcode 5?
Do you have the tutorials for the various app templates such as single view or master detail app version?? Hey Suriya, not at the moment, but thanks for that suggestion! Motivating Tutorial. Thanks for making the App development not that intimidating after all. Hey Nejc, I want to introduce the syntax commands little by little.
Is that a good way for you to learn, in your opinion? Instead of trying to learn all the commands at once before doing any practice. I appreciate your feedback! The clarity and detail is perfect. Thank you. Thank you for this wonderful website… i am new to programming and it helped me a lot… I was wondering if i could get some more information like dealing with tables and images…. Are there any books on xcode 5 in the market or any links for free!!!
Hey Rashu, thanks for your comment. There are actually a lot of UITableView tutorials out there! Hope that helps! Chris, Thank you for the Tutorial. I am totally new to the mobile app development environment. I am on Microsoft Window platform. Do I have to have Mac in order to develop the iPhone and iPad apps? Hello Rose, unfortunately you do, but some people have had success using a virtualization program like vmware to run OSX on their PC and have been able to install Xcode and build iOS apps.
Hey Melody, which version of OSX do you have? Do you have the Mac App Store? You made my day! Amazing article the effort you put in to make this article will definitely help a lot of people. Keep it up!! Great tutorial so far. Thank you…. Followed all your parts. Eagerly waiting for part 5. Thank you again. Is there a date for part 5 release? This is absolutely fantastic write-up!

If the above constraints causes problems on smaller screens, remove the width constraint, and add some space by setting the leading and trailing constraints to about You can do so by clicking View as: at the bottom of Interface Builder.
Then, select a different Device. The UI should now update and show you the different device, with different dimensions. Before we can create the game with Swift code, we need a way to change the User Interface UI with code. First, open the GameViewController. It looks a bit like this:. The GameViewController is the class that will govern what happens in the Add 1 game, and specifically its User Interface.
Connecting a UI component, from Interface Builder, to code in the view controller class, takes 2 steps:. The property will then hold a reference to the UI component, when the view controller loads.
First, add the following lines of code to the top of the GameViewController class:. All properties are optionals. The next step is connecting the UI elements to the outlet properties in Interface Builder. Do you see those small circles next to them? You should now see Score Label next to the scoreLabel property.
Make sure to repeat the steps for the other 3 outlets! You should end up with 4 outlet connections. Note that a default outlet connection, for view , is already present. This string, such as "" , consists of 4 characters. A new Swift file appears! First, add the following statement to the file.
You can add it right below import Foundation. The extension block tells Swift we want to extend the String type. The above code is called a function declaration. It has one parameter length of type Int , and its return type is String. Differently said, the function accepts an integer as input and produces a string as output. The static keyword is used to add this function to the class String , rather than an instance of String. This is often called a class method , as opposed to an instance method.
You can use it to include a variable in a string. First, switch over to the GameViewController. Then, add the following property to the top of the class, below the outlet properties:. Easy, right? But what is the type of the score property? In the above code, the 0 is an integer literal of type Int.
Based on that, we can infer that score has type Int. These functions will help us manage the game, later on. It merely updates the score label, with the current score. Two things stand out here, though! Quick question: Why are we adding such simple functions to the class? Whenever we need to update the score or number labels, we can just call that function. The viewDidLoad function is the starting point of any view controller.
At that point, the view is loaded but not yet shown on screen. At the start of the Add 1 game app, the score needs to be set to zero, and we also want to show the first random number to the user. Guess what? We just coded the perfect functions for that purpose. Your function should now look like this:.
What does override mean? Every view controller subclasses that UIViewController class, and inherits its functionality. When we want to customize some of its functionality, we can override the function and customize its implementation. The super. Quick Question: Can you assert what the text inside the score label and number label is, at the start of the game?
The first step is to respond when the user has edited the text of the input field. First, make sure to add the following function to the GameViewController class:. This function is going to be called when the user edits the text in the input field. This is similar to an outlet. You can also connect actions to UI elements with code. This mechanism is called target-action. Next up, we want to grab hold of the text inside the input field.
First, add the following code inside the inputFieldDidChange function:. What you get, is a guard let block that evaluates whether an expression is nil. When a guard let expression is nil , the else block is invoked, which will return and exit the function. With guard let , the constant you defined can be used throughout the function scope. We can use numberText and inputText constants in the rest of the function. This is counter-intuitive compared to if let , whose constants are only available inside the conditional.
However, guard exits the function, and scope, which hopefully makes up for the confusion…. The inputFieldDidChange function will be called for every change in the input field, which means for every character the user types in there. We only want to respond to complete input, i. Add the following code to the inputFieldDidChange function, below the previous code. The code will return and exit the function when the number of characters in the inputText string is not 4.
By the way, we could have used an if statement here, but a guard statement is often more descriptive. Here, check out these two:. We now have a handle on both the number string, and the input string.
Both have type String. If each of the digits is equal to the other, plus one, we have a correct result. To that end, we need a way to access the individual digits in the number strings. In many programming languages, you can just treat the string as an array of characters, and get, for example, the third character like this: inputText[ 2 ].
Unfortunately, dealing with strings in Swift is not that easy. There are 2 things you need to understand here:. Note: The integer at: function is only meant for the Add 1 game app! This approach makes sense, because the user only needs to make one mistake for the entire input to be incorrect. First, add the following code below the last guard statement:.
Simple, right? This variable is going to keep track of whether the result is correct.
