Ready to get your hands dirty in Xcode and build something? Want to learn Swift programming too? In this Xcode tutorial, you’ve learned about the various parts of the IDE and how to use Xcode for writing code and building user interfaces. If you chose Storyboards as your UI building option when you created the Xcode project, then your project will have a file called Main.Storyboard.Ĭlick this file and the Editor Area will change to the visual UI designer known as Interface Builder. How to use Storyboards and Interface Builder In this Xcode tutorial however, I’ll show you how to work with both options inside the Xcode Editor Area. I’ve written a SwiftUI tutorial so check that out if you want to move forward with that! However, since Apple is moving forward with SwiftUI, it’s a better investment for the future but at the present moment, you’ll be limited with the amount of help and educational content you can find on it. Most of my tutorials are based on Storyboards because it was the easiest way for beginners to grasp. Should you use Storyboards or SwiftUI?Īs a beginner, most of the tutorials you’ll find on the internet right now will based around Storyboards and UIKit since SwiftUI was just released. Xcode 11 has a special Preview Canvas pane that shows your user interface change in real time as you write the code to modify your user interface. Lets see these in below example.SwiftUI was released in late September 2019 as a new way to build user interfaces by writing code. Some other useful String functions are strlen() that returns the length of the String and strpos() that can be used to search any character or text in the String. We can use period (.) to concat two Strings. String is a stream of characters and in PHP we can use single or double quote with value to create a String and we can assign it to any variable. 
Parameter Scope – A parameter is a local variable passed to the function by the code calling it. We can use static variable to count the number of times a function is executed. The static variable is however local to the function only and can’t be referenced in other functions. Static Scope – If you want a local variable not to be deleted after the function is executed, you can declare it as static. PHP also stores all the global variables in an array $GLOBALS and using variable name, it can be accessed using this array directly anywhere in the PHP script.Ībove PHP script can also be written in following way Global Scope – If the variable is declared outside of a function then its scope is global and if we want to access a global variable inside a function, we need to use global keyword. The above script won’t print anything because echo statement is trying to lookup the local scope variable $var that is not initialized. 
Local variables are deleted as soon as the function is executed. Local Scope – If we declare a variable inside a function, then its scope is local and it can only be accessed with in the function.PHP Variables has four different scopes – local, global, static and parameter. We don’t need to declare the type of variable, PHP automatically converts the variable to correct data type.
Variable names are case sensitive ($a and $A are two different variables). A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ). Variable name must begin with a letter or the underscore character. A variable starts with the $ sign, followed by the name of the variable like $abc.
