[instruction 1]
why it doesn’t accepted?

print(transform ( strings: strings, transformer: {(str: String) -> String in
  return String(str.reversed())
}))

and provided solution doesn’t accept too

print(transform ( strings: strings, transformer: {(str: String) -> String in
  return String(str.reversed())
}))

these alert " Did you call the transform function with the strings array and an inline closure? Be explicit with the types."

edit > provided solution is this.

print(transform ( strings: strings ) { (str: String) -> String in
  return String(str.reversed())
})

Hi there. Even it is already answered, I agree with your soluation as it is the most explicit as possible and the one provided in soluation benefits from trailing closure and omits label “transformer” that’s why cannot be considered as the most explicit one.

Can someone explain this portion to me? where does str come from? and is there a way to define a variable a different way?

The Closure syntactic sugar question needs to be re written.

Hmm, what variable are they pulling from as it is not what is set at the beginning.

I second duckate. The hint makes reference to the closure parameter so I would expect it to be in the answer. Sad to see that in 3 years nothing has changed. What are we paying for?

Agreed. Most explicit is not recognized.
