9,439 PointsOut of range error.
So I've tried out the following code in Xcode playground but it didn't work.
var results: [Int] = []
for multiplier in 1...10{ results[multiplier] = multiplier * 6 }
It seems valid to me but the compiler says "fatal error. Out of range" Since it says "out of range" I somewhere try to refer to a non-existing element in the array. Why is it invalid? Am I allowed to use only "append" method in Swift in such case and not assigning a value directly to the pointed element?

9,439 PointsNevermind, I see the error... Here's the valid code: var results: [Int] = []
for multiplier in 1...10{ results[multiplier-1] = multiplier * 6 }
