Destination arch

[idan-fido]

Add option arch to input 'arm64' | 'x86_64' | 'i386'

arch is required (for example) when building on mac M-series with unsupported arm project dependancies

xcodebuild \
  -workspace iosApp.xcworkspace \
  -sdk iphonesimulator \
  -destination 'platform=iOS Simulator,arch=x86_64' \
  build
