我有以下Swift 2.x语法：
if let columnType = String.fromCString(sqlite3_column_decltype(pStmt, i))?.uppercased() {
我正在尝试将我的代码转换为swift 3.0。但是我不能让这个声明发挥作用。目前我有以下内容，但它给了我：“不能对'String'类型的非可选值使用可选链接”
if let columnType = String(cString: sqlite3_column_decltype(pStmt, i))?.uppercased() {
答案 0 :(得分：2)
String(cString:)不返回可选：
