We will stop only if the jump length from the current position is zero and the current position is the furthest we can jump from any preceding position.

func canJump(_ nums: [Int]) -> Bool {
    if nums.isEmpty {
        return false
    }
    var maxReach = 0
    for i in 0..<nums.count - 1 {
        if maxReach < nums[i] + i {
            maxReach = nums[i] + i
        }

        if nums[i] == 0 && maxReach == i {
            return false;
        }
    }
    return true
}
