Over the years, we have received numerous requests from our user community to provide a Fiddler build for OS X. So we have ported the latest version of Fiddler to the Mono Framework which in turn supports OS X—and you can grab the beta bits today.
We're proud to debut our newest release of AppBuilder, version 3.5. We concentrated all our efforts on bringing Angular 2 and NativeScript front and center. This is our first step on a long journey for the product.
