Describe the feature

Now unity plugin use version

<iosPods>
      <iosPod name="Branch" version="~>1.39.2" bitcodeEnabled="true" minTargetSdk="9.0" addToAllTargets="false" />
</iosPods>

but latest version 1.45.2

And as i understand version 1.45.2 will be non used.

Can you pls upgrade unity plugin for using latest iOS plugin version?
