  public static hideHouseExterior = async (vp: ScreenViewport) => {

    const categoryIds = await Visualization.getCategoryIds(vp.iModel);

    const categoriesToHide = ["'RevitDynamic.SWall'"];

    const query = `SELECT ECInstanceId FROM RevitDynamic.SWall(${categoriesToHide.toString()})`;


    const result = iModel.query(query, undefined, { rowFormat: QueryRowFormat.UseJsPropertyNames });

See below attached image:

i wrote this visualization code to hide my wall-category from the view but it is not hiding from the view.

Use the debugger to confirm hideHouseExterior is being called, that your query is returning expected results, etc.

i dint understood can you please have some examples for better understanding

Use ctrl-shift-I to open your browser's development tools.
Stick a breakpoint on the last line of getCategoryIds.
Run your app.
Confirm your breakpoint gets hit. If it does, inspect the contents of categoryIds to confirm it contains the categories you expect it to.
