swift - 无法为类型“sqlite3_destructor_type”调用初始化程序

Question

到目前为止，Martin R 的回答非常有效。但是从 Swift2 开始，它现在引发了错误

无法使用类型为“（COpaquePointer）”的参数列表调用类型“sqlite3_destructor_type”的初始化程序

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

取自@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)
