ios - 类型 'DispatchQueue.Attributes' 没有成员 'serial'

我已经使用Xcode8beta4将现有的Swift2.3代码转换为Swift3.0。Xcode自动将语法转换为Swift3.0,但它无法创建串行调度队列。privateletserialQueue=DispatchQueue(label:"identifier",qos:DispatchQueue.Attributes.serial) 最佳答案 不再有.serial属性,但是调度队列是默认情况下是串行的,除非您指定.concurrent属性:letserialQueue=DispatchQueue(label:"label")let
