Description Larry O'Brien 2017-08-01 00:53:48 UTC
According to https://developer.apple.com/documentation/vision/vndetectbarcodesrequest the types for the properties are:

class var supportedSymbologies: [VNBarcodeSymbology]
var symbologies: [VNBarcodeSymbology]


while the current iOS 11 bindings have them as:

public static string[] SupportedSymbologies { get; }
public virtual string[] Symbologies { get; set; }"

Comment 1 Sebastien Pouliot 2017-08-01 03:05:54 UTC
It's a NSString subclass, i.e. from ObjC header (or web docs)

> typedef NSString *VNBarcodeSymbology;

that we expose as a smart enum, so it should be NSString (virtual) with (non-virtual) wrappers for the enum.

@Alex please check that no other cases exists.
