var buckets: [[Int]] = .init(repeating:[],count:base)

the above code in book has errors message popup in xcode.

I changed to var buckets:[[Int]] = .init(repeatElement([], count: 10))

var buckets: [[Int]] = .init(repeating:[],count:base)

the above code in book has errors message popup in xcode.

I changed to var buckets:[[Int]] = .init(repeatElement([], count: 10))

I tested on my 9.4.1, and `var buckets: [[Int]] = .init(repeating: [], count: 10)`

is the correct syntax.

Itâ€™s not clear to me why this is an error. Could you give it another try?

hi, Kelvin:

I tested again in the morning, it work fine now. it is weird.

import Foundation

extension Array where Element == Int {

```
public mutating func radixSort()
{
let base = 10
var done = false
var digits = 1
while !done {
//var buckets:[[Int]] = .init(repeatElement([], count: base))
var buckets: [[Int]] = .init(repeating:[],count:base)
done = true
forEach {
number in
let remainingPart = number/digits
let digit = remainingPart%base
buckets[digit].append(number)
if remainingPart > 0
{
done = false
}
}
digits *= base
self = buckets.flatMap{$0}
}
}
```

}
