无法为类型'sqlite3_destructor_type'

Question

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

  

无法使用类型为'（COpaquePointer）'的参数列表调用类型'sqlite3_destructor_type'的初始值设定项

在这些方面：

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

从@MartinR提供的github帖子中获得答案

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