It is important to know the differences between a variable and a constant. These are things you will use every day and luckily, it’s really simple to understand. Choosing the correct declaration (var or let) when creating objects makes your code safer and it encourages you to know your code inside and out. Declaring an object as a variable or constant is not only for integer values (as shown on this page), the same also apply to other types like strings, integers, arrays and dictionaries.var In Swift, var means variable. A variable is an object that can be mutated, or changed.Example: In our example code below, we create an object named interestRate. We declare it as a variable by adding “var” before the name. Because we declared it a variable, this object can be updated whenever our interest rate changes.

Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works.

This book provides: - A tour of the language. - A detailed guide delving into each language feature. - A formal reference for the language.

Swift makes creating and modifying arrays really easy.  When you create your array, you don’t have to initialize it with a certain type, if all of your given values are the same type.  Example: If you create an array and all of the initial values are Strings, Swift automatically infers that the array will be a string array.

Although Apple writes that “Swift’s String type is bridged seamlessly to Foundation’s NSString class.” assuming you have added and imported the Foundation framework, the containsString method should be available to use but unfortunately, this doesn’t seem to be the case currently.  So we must manually bridge it.
