1.Introduction to SwiftThe new development language, released by WWDC in 2014, works with OC on Mac OS and IOS platforms to build apps based on Apple platforms.After the swift2.0, the syntax was stable, and the swift4.0, released in 2017, changed, but only added some new features. These new features need to be run on Xcode9 to show the effect. It is worth mentioning that it supports UNICODE9, which means that you can use some image icons to act as variables.2.

Sometimes, it may take some time to read English documents. If you read Chinese documents, you may be afraid of inaccurate translation. In some cases, you do not need to write any word.

In Swift, a member variable (property) of a class does not need to be evaluated, but wants to execute a piece of code before (or after) assigning it a new value, which can be handled using Willset and didset. For example, the following code sample, the side length of a triangle (triangle) is always associated with a quad ( Square) is the same length as the edge.Class Triangleandsquare {var Triangle:equilateraltriangle {Willset {Square.sidelength = New

should understand, because in the objective-c = = comparison is a reference, because arr1 and arr2 are two different objects, so even if their values are the same, but their references are not the same. So = = comparison will fail. The second comparison is Nsarray's Isequaltoarray method, which is used to compare values because the values of the two arrays are the same, so the isequaltoarray comparison method returns 1.equatable ProtocolWe learned about the workings of the equality operation th
