swift - 无法为类型 'sqlite3_destructor_type' 调用初始值设定项

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

Cannot invoke initializer for type 'sqlite3_destructor_type' with an argument list of type '(COpaquePointer)'

在那些行中:

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@MartinR 提供的 github 帖子，答案是

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