Introduction to Closures in Swift 3
Jayven N

Thanks, easy to follow for a beginner. One thing I could not figure out in general is the intention of the „in“ keyword. As I understand Swift syntax and APIs shall be in a form that its easy to build an English sentence with it. As a non native English speaker I’m not able to do that with a closure and the „in“ keyword. Also found no explanation in the internet. Do you have one for me? Would be easier to recognize :)
