Dear swifters.
I have an proposal for autocreation of optional variables
This idea came from below situation
I have to addtional header to NSURLSessionConfiguration like this
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
config.HTTPAdditionalHeaders?["Some-Additional-Info"] = "1992-08-01"
here is the problem
how to be sure not nil for HTTPAdditionalHeaders in
defaultSessionConfiguration
may be nil or not nil, I read api reference of HTTPAdditionalHeaders but,
did't see for value state of creation.
yeah, I know. it's optional. so may be I should thought it must be nil. but
really must be? I think it's not very clear logic.
anyway, HTTPAdditionalHeaders was nil. so i have to solve, and solve like
this.
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
var headers = config.HTTPAdditionalHeaders ?? [NSObject: AnyObject]()
headers["Some-Additional-Info"] = "1992-08-01"
May be another way to solve this.
*so I suggest autocreate parameter or something like that*
NSURLSessionConfiguration have this variable
public var HTTPAdditionalHeaders: [NSObject : AnyObject]?
*change above things to like below*
public *autocreate* var HTTPAdditionalHeaders: [NSObject : AnyObject]? {
*create* { return [NSObject: AnyObject]() }
}
let headers = config.HTTPAdditionalHeaders must be return nil
but
config.HTTPAdditionalHeaders["SomeThinkConvenient"] = "YEAH~"
this is automatically create Dictionary and set key and value
What about this idea, Dears?
Thank you for reading.
