Append variables to an array using swift

I have 100 variables of type UITextField that are named as such

box00, box01, box02 ........ box99

I would like to assign to each of these boxes something, however I am stuck. I tried to programmatically stuff them all in an array but I am stuck with that as well.

When using a counter in the variable name my compiler doesn't recognize the variable. I tried making a nested for loop.

for i in 0...9{ for j in 0...9{ boxArray.append(box\(i)\(j)) } }

Any ideas what I do now that I'm in this situation? I want all of my 100 UITextField variables appended in an array without explicitly naming each one by one.
