Xamarin Forms Entry Suggestion from API

Hello,

NOTE: Unfortunately, i am unable to post links as i have just joined the forum.

I am new to Xamarin forms and i am stuck on a problem. I want an autocomplete to suggest items to a user entering text into a field. The data is to be retrieved from a REST Api showing the user the name of the product whilst the code behind is able to keep track of the product Id.

In my search, this does not seem to be straight forward. :/

I have implemented the code from xLabs autocomplete as per their sample.

Running on iOS i recieve this error.....

Objective-C exception thrown. Name: NSInternalInconsistencyException Reason: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).

The xlabs page does not seem to have any documentation anymore on their github wiki. :/

There is a similar bug reportedon another site, which i can't link to, where the solution is to downgrade to Xamarin.Forms 2.3.4.270 but this did not solve my problem.

1) Does anyone know what this error is and why it occurs using this example component?
2) Are there alternatives or design patterns for creating this effect?

There must be a simple approach to this. It's pretty standard.

How do you have an entry box, which autosuggests a answer and tracks the id of that answer.

Daniel
