Describe the bug

I'm trying to implement onfido-ios-sdk for mu nativescript-angular app. Here is the repo - hello-onfido

As per ios-sdk guide,
objective-c code

NSError *variantConfigError = NULL;
Builder *variantBuilder = [ONFaceStepVariantConfig builder];
[variantBuilder withPhotoCaptureWithConfig: NULL];
[configBuilder withFaceStepOfVariant: [variantBuilder buildAndReturnError: &variantConfigError]];

Nativesctipt code

this._faceVariantBuilder = ONFaceStepVariantConfig.builder();
 // console.log(this._faceVariantBuilder instanceof Builder);
this._faceVariantBuilder.withPhotoCaptureWithConfig(null);
this._configBuilder.withFaceStepOfVariant(this._faceVariantBuilder.buildAndReturnError(this._faceVariantError));

But _faceVariantBuilder created is NSObject, so I can not found withPhotoCaptureWithConfig method.

To Reproduce

Clone hello-onfido
add ios platform, and run this app.
It says,

file:///src/app/onfido/onfido.ts:80:28: [nativescript-onfido]: ERROR: TypeError: _this._faceVariantBuilder.withPhotoCaptureWithConfig is not a function. (In '_this._faceVariantBuilder.withPhotoCaptureWithConfig(null)', '_this._faceVariantBuilder.withPhotoCaptureWithConfig' is undefined)

Expected behavior

It should generate Builder type of object, instead of NSObject.

Sample project

Hi @heena-1993, thank you for the excellent report! We've made a fix for the issue and it will be released with version 6.4.1 of tns-ios.

The RC has been published in NPM and you can now try it with tns platform add ios@rc
