Objective C to Swift translate

Question

I am having difficulties translating an Objective C "method" to swift. Any help would be greatly appreciated. Thank you.

Objective C

NSDictionary *fields = @{@"msg": @"connect", @"version": version, @"support": support};

My attempt in Swift (wrong)

let fields:Dictionary = {"msg": "connect", "version": version, "support": support}

Answer 1

Swift uses square brackets for Array and Dictionary:

let fields: Dictionary = ["msg": "connect", "version": version, "support": support]

it's just the format of the content between the brackets which determines what it is
