Doubt with creation of For on Swift 3

Asked

I’m following an iOS course and in the course shows the for in this way:

for var i = 1; i <= 10; i++ {

}

But I have an error message, has it changed? How could this be done in the new way?

error: Creatureloop.playground:6:1: error: C-style for statement has been Removed in Swift 3

  • It has. That’s one for that came from C. The IDE is saying that you have a better way to do it and that you should follow the language with its syntax. https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/ControlFlow.html
