ios - NSDictionary vs [String:AnyObject] in Swift -

-

i updated external swift library, , 1 of methods has changed face from:

public convenience method(data:nsdictionary?) { ... }

to:

public convenience method(data:[string: anyobject]?) { ... }

  1. what mean?

  2. initially, old, @{@"optiona":@yes} passed data argument. new need pass 2 items. thinking write @{@"optiona":@yes,@"optionb":@no}, correct?

  1. it means parameter swift dictionary , no objective-c nsdictionary anymore.

  2. to pass data, use square brackets instead of curly brackets , remove "@" (in swift)

["optiona":true, "optionb": false]

if calling method objective-c, method parameter should exposed nsdictionary , right @{@"optiona":@yes,"optionb":@no} missed @-sign before optionb
