Swift 3 - 将 Int32 转换为 Int

Question

使用 Swift 3 并且在 IF 语句中比较 Int32 和 Int 时遇到问题。

// myIntFromCoreData is an Int32
// kMyConstant is an Int

if myIntFromCoreData == kMyConstant // error: Binary operator "==" cannot be applied to operands of type 'Int32' and 'Int'
{
     Log("Cool")
}

因此，我尝试使用以下方法将值转换为 Int32 或 Int：

myint32.intValue // Value of type 'Int32' has no member 'intValue'

myint32 as Int // Cannot convert value of type 'Int32' to type 'Int' in coercion

kMyConstant as Int32 // Cannot convert value of type 'Int' to type 'Int32' in coercion

但一直出现上述错误。任何人都可以提供一些指导如何处理这个吗？
