I want to start using the Swift ternary operator so that I don't set values but I fire different functions.

if position.x < kWidth / 2 ? fireLeft() : fireRight()

It does not work, and I am actually quite by that. What can I do to make it work?


The if keyword is not needed in the ternary operator.

Swift Ternary Conditional Operator (With Examples), For simple conditions, you can evaluate it in a single line with less code than if-​else. Example 1: Simple example using ternary conditional operator. print(true &&  Swift Ternary Conditional Operator Swift Ternary Conditional Operator In this article, you will learn to use conditional or ternary operator to alter control flow of the program. The ternary conditional operator "? :" is a shorthand for if-else statement.


You should not write if keyword while using ternary operator.

Your statement would be:

position.x < kWidth/2 ? fireLeft() : fireRight()

The ? operator reads as if the statement before ? returns boolean TRUE, then call the fireLeft() function else call fireRight() function.

Ternary Operator in Swift - SyntaxDB, Ternary Operator in Swift. The ternary operator is used to execute code based on the result of a binary condition. It takes in a binary condition as input, which makes it similar to an 'if-else' control flow block. It also, however, returns a value, behaving similar to a method. Like I said, the ternary operator is used with three values: the check to run, what to return if the check is true, and what to return if the check is false. For example, if we had a score constant that contained an integer, we could make a result constant equal either to “Pass” or “Fail” depending on the value of score :


use : (condition) ? (option 1) : (option 2) it works like this :

if (condition = true) {
(option 1)
}else {
(option 2)
}

Basic Operators, Like C, Swift has only one ternary operator, the ternary conditional operator ( a ? b : c ) The same method is applied when calculating the remainder for a negative the operator is used to determine an initial value for a String variable called  In the above program, the function accepts two parameter of type Int. The function call uses the argument label of & and which makes sense while calling the function as sum(of: 2, and: 3) instead of sum(a: 2, b: 3). Also, the function body uses the parameter name a and b instead of of & and which also makes more sense while applying operations.


Custom Ternary Operators in Swift, Curried functions. A curried function is one that, instead of being called one time with multiple parameters, can instead be called multiple times,  Function Declaration − tells the compiler about a function's name, return type, and parameters. Function Definition − It provides the actual body of the function. Swift 4 functions contain parameter type and its return types. Function Definition. In Swift 4, a function is defined by the "func" keyword.


Swift 3 Ternary Conditional Operators, These are formatted so you can copy the code straight into your Swift Playground files. Ternary Conditional Operators are a shorthand way of making something Swift 3 Gesture Recognizers · Swift 3 Delaying a Function Call (aka Perform  Expressions¶ In Swift, there are four kinds of expressions: prefix expressions, binary expressions, primary expressions, and postfix expressions. Evaluating an expression returns a value, causes a side effect, or both. Prefix and binary expressions let you apply operators to smaller expressions.


Swift Ternary (?:) Operator, In swift, ternary (?:) operator will perform the same operation whatever is performed by the if-else statement but it's a shortcut method to perform if-else statement  The operator is a compound assignment operator because the operator performs both task subtraction and assignment at the same time. You can find examples on bitwise operators on this article Swift Bitwise operators .
