迁移到 Swift 5 后 SQLite.swift 出现问题

Question

我使用 SQLite.swift 并在升级到 Swift 5 后库中出现错误。请帮我重写方法。

错误：

'withUnsafeBytes' is deprecated: use `withUnsafeBytes<R>(_: (UnsafeRawBufferPointer) throws -> R) rethrows -> R` instead

代码：

public var datatypeValue: Blob {
    return withUnsafeBytes { (pointer: UnsafePointer<UInt8>) -> Blob in
        return Blob(bytes: pointer, length: count)
    }
}

Answer 1

Till SQLite.swift 没有发布任何带有修复的更新，您可以尝试手动修改 SQLite/Foundation.swift for fromDatatypeValue(_ dataValue: Blob) 函数和计算的属性 datatypeValue这样：

public static func fromDatatypeValue(_ dataValue: Blob) -> Data {
    return Data(dataValue.bytes)
}

public var datatypeValue: Blob {
    return withUnsafeBytes { (pointer: UnsafeRawBufferPointer) -> Blob in
        return Blob(bytes: pointer.baseAddress!, length: count)
    }
}
