无法为类型'sqlite3_destructor_type'调用初始化程序 [英] Cannot invoke initializer for type 'sqlite3_destructor_type'

问题描述

到目前为止，Martin R的答案运作良好.但是从Swift2开始，现在会引发错误

So far the answer from Martin R has worked perfectly. But starting with Swift2 it now raises the error

无法使用类型为((COpaquePointer)''的参数列表来调用类型为'sqlite3_destructor_type'的初始化程序

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

在这些行中:

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))

推荐答案

来自github帖子，由@MartinR提供，答案是

Taken from the github post provided courtesy of @MartinR the answer is

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