无法为类型“sqlite3_destructor_type”调用初始化程序

Question

到目前为止，answer from Martin R已经完美地工作了。但是从Swift2开始，它现在会引发错误

不能使用类型‘(Sqlite3_destructor_type) '(COpaquePointer)’的参数列表调用类型“COpaquePointer”的初始化程序

在这些行文中：

private let SQLITE_STATIC = sqlite3_destructor_type(COpaquePointer(bitPattern: 0))      // https://stackoverflow.com/a/26884081/1271826
private let SQLITE_TRANSIENT = sqlite3_destructor_type(COpaquePointer(bitPattern: -1))

Answer 1

摘自由@MartinR提供的github邮件，答案是

internal let SQLITE_STATIC = unsafeBitCast(0, sqlite3_destructor_type.self)
internal let SQLITE_TRANSIENT = unsafeBitCast(-1, sqlite3_destructor_type.self)
