swift-conditionals-lab's Issues

Laboratory do not have solution

I mean in Branch solution no files. I would like to compare I did my lab right or wrong!

Solution to Question 11

The solution to question 11 seems flawed: https://github.com/learn-co-curriculum/swift-conditionals-lab/blob/solution/MyPlayground.playground/Pages/solution.xcplaygroundpage/Contents.swift#L116

Statements like myAccount + 10 have no effect, as the new value is not stored in a variable. To update the value of myAccount, the code should be myAccount = myAccount + 10 or myAccount += 10.

However, Swift does not allow modifying arguments unless you put inout before the parameter type (e.g. myAccount: inout Int). I don't believe this concept has been covered in the curriculum so far.

I propose either revising question 11 itself, revising the solution to use inout and more effective statements like myAccount = myAccount + 10 (and including a note to students explaining the solution), or introducing inout before this lab.
