Swift:搜索数组中包含数字的数组索引的更好方法？

func searchIndex(in array: [Int], for number: Int) -> [Int] {
    var indexes: [Int] = []
    for (index, value) in array.enumerated() {
        if value == number {
            indexes.append(index)
        }
    }
    return indexes
}

func searchIndex(in array: [Int], for number: Int) -> [Int] {
    let indexes = array.enumerated().filter { $0.element == number }.map { $0.offset }
    return indexes
}

func searchIndex(in array: [Int], for number: Int) -> [Int] {
    let indexes = array.indices.filter { array[$0] == number }
    return Array(indexes)
}
