I have the code outlined below, but the final call to dispatch_group_notify never occurs
// Get friends:
dispatch_group_enter(self.dbGetQueue)
getFriends.observeSingleEventOfType(.Value, withBlock: { snapshot in
for detailData in snapshot.children {
print(detailData)
self.friends.append(Member(userID: detailData.key, userName: detailData.value!["userName"] as! String))
}
dispatch_group_leave(self.dbGetQueue)
})
// Get group memebers:
dispatch_group_enter(self.dbGetQueue)
getGroupMembers.observeSingleEventOfType(.Value, withBlock: { snapshot in
for groupMemberDetail in snapshot.children {
print(groupMemberDetail)
if groupMemberDetail.key != FeastGlobal.sharedInstance.userID {
self.groupMembers.append(groupMemberDetail.key)
}
}
})
// Get group invites presently out:
dispatch_group_enter(self.dbGetQueue)
getFriendMemberInvites.observeSingleEventOfType(.Value, withBlock: { snapshot in
for groupInvitePresentlySentDetail in snapshot.children {
self.groupInvitesSent.append(groupInvitePresentlySentDetail.key)
}
dispatch_group_leave(self.dbGetQueue)
})
dispatch_group_notify(self.dbGetQueue, dispatch_get_main_queue()) {
// Final load of who is left of conacts (not user or friend)
// Have list of friends, now set to iterate through:
// 0: not invited yet, 1: invited (eiter declined or not replied yet) not , 2: Already a member -- will have alert noting user became a group member
print(self.groupMembers.count)
print(self.friends.count)
print(self.groupInvitesSent.count)
for aFriend in self.friends {
print("Friends name is: " + aFriend.userName)
var inviteStatus = Invite(userName: aFriend.userName, status: "not invited yet", statusSort: 0, name: aFriend.userName, userID: aFriend.userID)
if self.groupMembers.contains(aFriend.userID) {
inviteStatus.statusSort = 2
inviteStatus.status = "member"
self.memberStatuses.append(inviteStatus)
} else if self.groupInvitesSent.contains(aFriend.userID){
inviteStatus.statusSort = 1
inviteStatus.status = "invited"
self.memberStatuses.append(inviteStatus)
} else {
self.memberStatuses.append(inviteStatus)
}
}
self.tableView.reloadData()
}
How can this be alleviated?
