Legacy Constructor Violation: Swift constructors are preferred over legacy convenience functions. (legacy_constructor)
提问by etayluz
I'm getting a SwiftLintwarning on this line:
我在这一行收到SwiftLint警告：
return UIEdgeInsetsMake(topInset, leftInset, bottomInset, rightInset)
This is the warning :
这是警告：
Legacy Constructor Violation: Swift constructors are preferred over legacy convenience functions. (legacy_constructor)
Legacy Constructor Violation：Swift 构造函数比遗留的便利函数更受欢迎。(legacy_constructor)
I'm getting a warning on this line as well:
我也在这条线上收到警告：
return CGRectInset(bounds, insetX, insetY)
Legacy CGGeometry Functions Violation: Struct extension properties and methods are preferred over legacy functions (legacy_cggeometry_functions)
遗留 CGGeometry 函数违规：结构扩展属性和方法优于遗留函数（legacy_cggeometry_functions）
What is the Swift version for UIEdgeInsetsMakeand CGRectInset?
UIEdgeInsetsMake和的 Swift 版本是CGRectInset什么？
回答by keithbhunter
Swift wants you to update to the new struct initializers for those types, instead of the old C constructors. So your inset initializer would be changed to this:
Swift 希望你更新这些类型的新结构初始化器，而不是旧的 C 构造器。因此，您的插入初始化程序将更改为：
return UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
The CGRectInsetC method was changed to be a method on the CGRectstruct.
在CGRectInsetC法改变为是对一个方法CGRect结构。
return bounds.insetBy(dx: insetX, dy: insetY)
