Hi,
ok, based on the package you sent me, all is well, you just need to use the linker wizard because you are using "set property", which needs the linker to work on IOS.
also, always prefer using a "proper" dedicated action whenever possible, using "Set property" to activate a Gameobject is not a good idea, instead, prefer using the action "Activate GameObject". You should only use set/Get property when you can't make find an action or custom action and you can't code one.
Bye,
Jean
