All these calls return nil for me:
所有这些调用都为我返回nil:
Int("ff000000", radix: 16)
Int("#ff000000", radix: 16)
Int("0xff000000", radix: 16)
I must be doing something wrong.
我一定是做错了什么。

Use this code, this is working properly.
使用这段代码，这段代码运行正常。
let value1 = Int64("aabb00ddff",radix: 16)
The instead of using Int you should use Int64, because when you convert Hex to Int resulted value will be bigger than expected.
与使用Int不同，您应该使用Int64，因为当您将十六进制转换为Int结果值时，结果值将大于预期值。
Int will also work.
Int也会工作。
