How to make zombies spawn faster and in larger groups using a command block on the Switch?
Here are several simple things that may help:
I don't know about increasing the total spawn rate of zombies but you could increase the concentration of hostile mobs by lighting up nearby areas as this forces the hostile mobs to only be able to spawn in the dark areas that you want them to spawn in.
Alternatively, you could build the area in which you want zombies to spawn in the air to make sure that you only load in the platform so that hostile mobs can only spawn on the platform. If you you this method you will need to be at least 128 above the highest point on the ground to increase efficiency.
You could also increase the tick speed thus increasing the amount of mobs spawning
Here is a slightly more complex way that works on Java but I am not sure about Bedrock:
- Spawn in zombie with a command block.
- Use spread player command to spread all the zombies in a certain area into another area.

If possible, as commented by several people, could you be more specific and give us more information about why you need this for, whether you have access to command (which I assume you do as it is a tag) and several other factors that could help us help you.
