Dear all
I've found a serious Bug in JSONEncoder SR-6131 <Issues · apple/swift-issues · GitHub; and would like to fix it.
This bug cause JSON encoding issues on Double when using a local that does not use dot as decimal separator e.g « fr_FR » (we use a coma)
Demonstration of the issue :
import Foundation
// Required to call setLocale
import Darwin
// Let's set to french
setlocale(LC_ALL,"fr_FR")
struct Shot:Codable{
let seconds:Double
}
let shot = Shot(seconds: 1.1)
do{
let data = try JSONEncoder().encode(shot)
if let json = String(data:data, encoding:.utf8){
// the result is : "{"seconds":1,1000000000000001}"
// The decimal separator should not be "," but "."
print(json)
}
}catch{
print("\(error)")
}
exit(EX_OK)
I would like to propose my fix, test it and, but i’m not mastering the contribution mechanism.
Where should i start?
I ve forked GitHub - benoit-pereira-da-silva/swift-corelibs-foundation: The Foundation Project, providing core utilities, internationalization, and OS independence
I have a very simple Unit test that demonstrates the issue.
How can i test my
Thanks
