[Swift] Bool value conversion

[orkenstein]

There is an issue with Bool value conversion to GET URL parameters.
It's described here, as well as the solution:
http://stackoverflow.com/questions/36185530/how-to-check-dictionary-value-to-be-exactly-a-bool/36186159#36186159

Swagger server implementation accepts Bool as true/false only. So this breaks some logic.

@orkenstein thanks for sharing the fix. May I know if you've cycle to contribute a fix?

A good starting point is to add convertBoolToString to APIHelper: https://github.com/swagger-api/swagger-codegen/blob/master/modules/swagger-codegen/src/main/resources/swift/APIHelper.mustache

Yep, no problem, I will, whet I get some time.
Swift templates requires 2 more crucial improvements:

• support array as root object of http body
• support body and query parameters at the same time.

Alamofire does not allow to do this by default. I've already found the solution, but I use custom templates and need somebody to review my code.

@orkenstein thanks!. To run the integration test for Swift Petstore after making the change, please do the following:

mvn clean && ./bin/swift-petstore.sh
cd samples/client/petstore/swift/SwaggerClientTests && mvn integration-test

support body and query parameters at the same time.

That's a pretty big issue indeed :( is there a specific issue on this repo for that?

[orkenstein]

@cjolif looks like no.

thanks @orkenstein, I created #2483 to track this one...

[wing328]

@cjolif thanks for opening an issue to track it and hopefully they will add the support soon.

PR merged. Issue closed.

For Swift 3 version:

static func convertBoolToString(_ source: [String: Any]?) -> [String:Any]? {
	guard let source = source else {
		return nil
	}
	var destination = [String:Any]()
	let theTrue = NSNumber(value: true)
	let theFalse = NSNumber(value: false)
	for (key, value) in source {
		switch value {
		case let x as NSNumber where x === theTrue || x === theFalse:
			destination[key] = "\(x.boolValue)"
		default:
			destination[key] = value
		}
	}
	return destination
}

Sample:

var quantity: Int64? = 4
var formParams: [String:Any?] = [:]
formParams["type"] = "abc"
formParams["quantity"] = quantity
formParams["hidden"] = NSNumber(value: true)
formParams["enabled"] = NSNumber(value: false)
formParams["easy"] = true

let nonNullParameters = APIHelper.rejectNil(formParams)
// output: ["hidden": 1, "quantity": 4, "enabled": 0, "easy": true, "delivery_type": "abc"]
let parameters = APIHelper.convertBoolToString(nonNullParameters)
// output: ["hidden": "true", "quantity": 4, "enabled": "false", "easy": "true", "type": "abc"]
