{Print ("same message")}else{Print ("Not the same message")}Conditional logic is very common in programming. Sometimes, you want-to-execute certain part of the code only if a certain condition is met. An if-else statement are one of the ways in Swift-control program flow. Here we compare the content of Message1 and message2 variables using the = = operator. If they ' re equal, the program prints "same messa

The switch statement in Swift, as long as the first match (case) completes, not through the bottom of subsequent cases (case), as it does in C and C + + programming languages. The following are common syntax for switch statements in C and C + +: Copy Code code as follows: switch (expression) { Case Constant-expression: statement (s); Break * Optional * * Case Constant-expression: st

(1) Swift and C language communicationIn Xcode, when the C language file is added to the SWIFT project, Xcode asks if the Create bridging Header is selected.The C language header file is then referenced in the bridging header.You can then use the C language function in the swift file.(2) Swift and OBJECTIVE-C communica

APP Store: Programming Dictionary-Swift version V1.0This is a dictionary that covers Swift's basic vocabulary and is also a word book that you can customize. The premise of learning programming is to learn English well, the traditional dictionary writing speed has not caught up with the speed of inventing new words in the computer industry. The application focuse

inference statement of the while loop body, and then decides whether the next iteration of the loop can continue to run. Attention: Assuming that the break statement above does not use the gameloop tag, it interrupts the switch code block rather than the while loop body. Using the Gameloop tag is a clear indication of which block of code the break is trying to interrupt. At the same time, note that it is not strictly necessary to use the Gameloop tag when calli

The framework packaging and swift programming languages have been introduced since iOS 8.0. We can mainly use the SWIFT programming language to package our own code into the framework. However, the current Xcode 7.x is not too smart to automatically import the framework package, so you need to do some cleanup.First, wh

Playground is the "what you can read and write" programming model as Swift launches. Playground literally means a playground, a casino. That is, in swift you can write code while previewing the programming effect. This programming developer or starter developer brings unprec

codes in these two methods that can abstract these different places and write them as a single, more general function? As shown below:Func Computeintarray (xs: [int]), [int] { var result: [int] = [] for x in xs { result.append (/* Something Using X */)} return result} To complete the above definition, we will need a new parameter to abstract out these different places:Func Computeintarray (xs: [int], f:int-i, int), [int] { var result: [int] = [] for x in xs { r
