B4i Library ExpressionEvaluator vor iOS

Is there a ExpressionEvaluator library for iOS like the one for Android?

You can use this class: https://www.b4x.com/android/forum/threads/class-b4x-eval-expressions-evaluator.54629/

Using B4xEval in B4i, I am getting the error : Target is null. Method called: Initialize
in sub Evaluate(Expression As String) on the line Nodes.Initialize

Any ideas?

Can you upload your project?

I tried it in a new project with just B4xEval and discovered it was due to not initializing the B4xEval object itself. The location of the error threw me.
