| Swift- Programming Language | |
| Swift is apples new rendition of a modern programming Language. It is an object orientated Language and element’s from JavaScript, C++, ruby, and many others. | |
| Using swift and xcode gives you access to auto complete methods, and a huge array of development tools at your fingertips. | |
| This will be a short introduction to they syntax of the Language. | |
| - Declaring a variable | |
| Any variable described outside the 'general' function is a golbal variable. | |
| must always like Javascript place 'var' infront of variable name | |
| -Delcaring Structures | |
| struct 'hashname'{ | |
| var name = "un-Named" | |
| var desc = "description" | |
| } | |
| - Delcaring Functions | |
| func 'Function Name'(argument : argument-type) -> 'output'/optional { | |
| - logic | |
| } | |
| example : | |
| func textFieldShouldReturn(textField: UITextField!) -> Bool{ | |
| textField.resignFirstResponder(); | |
| return true | |
| } | |
| - Declaing an array/ adding to an array | |
| first declare a variable - | |
| var array = [] or var array = []()' using the closed parenthases gives a closed description to an object if its native state was not that of an array' | |
| a simple function to add elements to our new array variable | |
| struct list{ | |
| var name = "un-Named" | |
| var desc = "description" | |
| } | |
| var lists = list[]() // Sets lists to empty array | |
| func AddElementsToArray(name: String, desc: String){ // passes fuc two arguemnts both strings | |
| var list.append() | |
| } |
