I'm writing a simple app to help keep track of notes and such for my job: running facebook ads for different proselyting missions of a church, and I've encountered a problem. The update_campaign function adds the new instance of Campaign to the mcs array, but for some reason it doesn't transfer the new campaign instances to the new_mission.campaigns array. As you can see, the original declaration of the new_mission variable includes a test campaign, which does print out. But, any attempt to add a new Campaign struct to the new_mission.campaigns array doesn't work. Even the little test button above the "Create" button doesn't work.
What makes things more confusing is the fact that the mission_leaders array does update and populate on my other view.
Any help would be appreciated, I'm still a little new to swift, thanks!
Here's my code, I've added notes for you guys in between double asterisks:
//window to make new mission
struct CreateMission: View {
//calls array of all missions
@Binding var all_missions: [Mission]
//new mission for imput
@State private var new_mission = Mission(
id: UUID(),
name: "",
mission_leaders: [],
campaigns: [Campaign(id: UUID(), name: "", start_date: Date(), status: .ACTIVE)])
//string arrays for leaders
@State private var leader_names_array = [""]
@State private var leader_roles_array = [""]
@State private var leader_pn_array = [""]
//string arrays for campaigns
@State private var campaign_names_array = [""]
@State private var campaign_dates_array: [Date] = [Date()]
@State private var campaign_status_array: [C_status] = [.ACTIVE]
var body: some View {
VStack{
//name of mission
TextField("Mission name:", text: $new_mission.name)
//list of mission leaders
//ADD DELETE BUTTONS

ForEach($leader_names_array.indices, id: \.self) { index in
