Swift中打印日志

Swift提供了两种打印方式

public func print(_ items: Any..., separator: String = default, terminator: String = default)

public func debugPrint(_ items: Any..., separator: String = default, terminator: String = default)

将需要打印的参数用(parameter)包裹即可

var name="jack"
print("name is \(name)")
debugPrint("name is \(name)")
