1、 Vertical Whitespace Violation: Limit vertical whitespace to a single empty line. Currently 2.
空白问题,要求代码之间的空白行为一行,当前是2行或多行就会提示,修改的话删除多余空白行就可以 2、 Type Body Length Violation: Type body should span 200 lines or less excluding comments and whitespace: currently spans 325 lines类的大小问题,当前要求一个类的大小是小于等于200行,不包括空白行和注释,当前是325行。修改这个很麻烦,只能进行类的拆分,但是有些类并不是越小越好,所以这条就根据当前类的自行考虑,并不一定需要照做 3、 Control Statement Violation: if, for, guard, switch, while, and catch statements shouldn't unnecessarily wrap their conditionals or arguments in parentheses.当使用if、for、guard、switch、while、catch等语句时,并不需要加多余的括号 错误 if (plateNo.count > 1) { ... } 复制代码正确 if plateNo.count > 1 { ... } 复制代码 4、 Opening Brace Spacing Violation: Opening braces should be preceded by a single space and on the same line as the declaration.括号前应该空一格,而不是紧挨着语句,并且要求与声明在同一行 5、 Vertical Parameter Alignment Violation: Function parameters should be aligned vertically if they're in multiple lines in a declaration.如果一个方法的参数分多行书写,则参数应该对齐 6、 Function Body Length Violation: Function body should span 40 lines or less excluding comments and whitespace: currently spans 48 lines方法大小的问题,方法应该小于等于40行,不包括空白行和注释 7、 Colon Violation: Colons should be next to the identifier when specifying a type and next to the key in dictionary literals.冒号违规问题,冒号应该靠左,并且右边有一个空格 let left:CGFloat = 90 错误 let left : CGFloat = 90 错误 let left: CGFloat = 90 正确 8、 Trailing Semicolon Violation: Lines should not have trailing semicolons.swift在行的结尾处不应该有分号 let left: CGFloat = 90; 错误 let left: CGFloat = 90 正确 9、 File Line Length Violation: File should contain 400 lines or less: currently contains 496文件应该小于等于400行 10、 Identifier Name Violation: Variable name should only contain alphanumeric characters: 'safe_bottom'变量名不能包含除字母数字外的其他字符 public let safe_bottom: CGFloat错误 public let safeBottom: CGFloat正确 11、Identifier Name Violation: Variable name should be between 3 and 40 characters long: 'vc'变量名定义应该在3-40个字符之间,用vc就只有2个字符,可以改为control等 12、 Force Cast Violation: Force casts should be avoided避免直接的类型强转 let show = item as! Chemistry 复制代码错误 if let show = item as? Chemistry { } 复制代码正确 13、 Unused Closure Parameter Violation: Unused parameter "model" in a closure should be replaced with _.当参数并没有使用的时候,建议把参数名用_替代 14、 Mark Violation: MARK comment should be in valid format. e.g. '// MARK: ...' or '// MARK: - ...'注释的格式错误,//和MARK中间需要有空格 15、 Comma Spacing Violation: There should be no space before and one after any comma.逗号格式违规,逗号应该紧跟字符,不要有空格,逗号后空一格 16、 Trailing Newline Violation: Files should have a single trailing newline.文件的结尾应该有一个空行 17、 Opening Brace Spacing Violation: Opening braces should be preceded by a single space and on the same line as the declaration.左大括号间距违规:左大括号前面应该有一个空格,并与声明在同一行 18、 Implicit Getter Violation: Computed read-only properties should avoid using the get keyword计算的只读属性应避免使用 get 关键字 19、 For Where Violation: where clauses are preferred over a single if inside a for在for循环语句中,如果你的判断语句只有一句,应该使用where而不是if 20、 Multiple Closures with Trailing Closure Violation: Trailing closure syntax should not be used when passing more than one closure argument.当函数有多个闭包的时候,最后不要使用尾随闭包,但是这个是一个非常恶心的提示,因为你用xcode的时候,xcode会自动帮你用尾随闭包,所以想不出现就需要自己手动改,很影响开发效率 foo.something(param1: { $0 }) { $0 + 1 } 错误 foo.something(param1: { $0 }, param2: {$0 + 1}) 复制代码正确 21、 Weak Delegate Violation: Delegates should be weak to avoid reference cycles.代理应该添加weak修饰符,避免循环引用 |
