is duplicated by:

  • SR-4849 Fixed integer widths not supported as JSON objects on Linux

relates to:

  • SR-1610 Cross-platform NSNumber coercion behavior

Issue Description:

Sample code:

import Foundation

let a: UInt8 = 1
let arr = [a, a, a]

print("Is array of UInt8 valid JSON? \(JSONSerialization.isValidJSONObject(arr))")

Tested on 3.1.
On Ubuntu 16.04, it prints `Is array of UInt8 valid JSON? false`.
On OSX, it prints `Is array of UInt8 valid JSON? true`.

This is the case for other types as well. Including CGFloats

I think you have to manually create NSNumbers to be cross-platform compatible in Swift 3.1. Right, @phausler?

This looks fixed in 4.1.3:

$ ~/swift-4.1.3-RELEASE-ubuntu16.04/usr/bin/swift
 Welcome to Swift version 4.1.3 (swift-4.1.3-RELEASE). Type :help for assistance.
 1> import Foundation 
 2. 
 3. let a: UInt8 = 1 
 4. let arr = [a, a, a] 
 5. 
 6. print("Is array of UInt8 valid JSON?
\(JSONSerialization.isValidJSONObject(arr))")
 Is array of UInt8 valid JSON? true
