//////////////////////////////////////// ////////////////////////////////////////

Implementation

//For fetching a random activity but you can specify your requirements like if you are thinking "Participants should be 3 but minimum price should be around 0.15. Also the type should be Social". So, you can do this - getCustomizedActivity(expectedParticipants: 3, minPrice 0.15, activityType: "social") :]
