如何使用OR子句在Swift中过滤数组(How to use an OR clause to filter an array in Swift)

 我试图通过匹配用户名或全名来过滤Swift中的对象数组。 
 
   filteredRegUserArray = regUserArray.filter {
                $0.userName.lowercaseString.hasPrefix(lowercasePrefix) || 
                $0.fullName.lowercaseString.hasPrefix(lowercasePrefix)}

I am trying to filter an array of objects in Swift by matching username or full name. 
 
   filteredRegUserArray = regUserArray.filter {
                $0.userName.lowercaseString.hasPrefix(lowercasePrefix) || 
                $0.fullName.lowercaseString.hasPrefix(lowercasePrefix)}
