Swift 1.1 language 7th function and closureIn programming, as the processing problem becomes more and more complex, the amount of code increases rapidly. Where a large number of code tends to repeat or approximate each other. The code will be difficult to maintain if it is not addressed in an effective manner. In order to solve this problem, the concept of functi

Ongetdata (Platform.width + x-scenewidth) }After this is done, we switch to the Gamescene class to continue coding: first let Gamescene follow the Protocolmainscene protocol, define a variable, and receive the variable that the platformfactory passed over:var lastdis

A For loop is a loop control structure that can be effectively written to perform a specific number of loops.
