After days of working through using the documentation, you really drove these concepts home with this tutorial. Thank you much for your delivery of this information!
Is this happening to anyone else?
self.postArray = querySnapShot!.documents.compactMap({Post(dictionary: $0.data())})
is returning zero results, but when I don't use Date, it goes through. Does anyone know why? Any response would be really appreciated.
Also, great video Brian! Liked and subscribed.
same problem over here
Jelle Geers yeah don’t use Date, use Timestamp. That’s what Firestore uses.
@@juanerenas4662 Thank you!
same here, removed the date and it worked.
@@juanerenas4662 Thank you so much!
Oh my god. I like this. thank you for upload!
Superb!! Thank you so much for your video!
flatMap is depreciated and is asking to use compactMap however that seems to be returning 0 results
self.postArray = querySnapShot!.documents.compactMap({Post(dictionary: $0.data())}) is what I have * never mind, for some reason Date was giving me an issues.
Same
I'm having the same problem. sweetArray is empty after parsing the data from snapshots. What was your solution?
@@veronikab__ did you find solution?
@@codic1160 Yes. In extension in Sweet file you should handle each parameter separately, instead of using guard let statement for all 3 parameters. So you can see where is the problem. In my case problem was with timeStamp parameter. Handle each parameter like this: let name = dictionary["name"] as? String ?? "Error! Name Field Not Found!". I opened an issue on Stackoverflow, so you can read more here: stackoverflow.com/questions/62138964/the-data-from-firestore-database-is-not-displayed-in-the-tableview
Could you please do one with sending photos???
Thank you so much for the tutorial. So easy to understand, and works amazingly.
Favorite firestore tutorial
Hi Brian. Great tutorial, however, the finished project, as is, on Github is incomplete. The storyboard is blank, the app delegate file seems to be missing the configure statement for Firestore, etc. Also, could you clarify why you need a struct in addition to the dictionary layout of Sweet? I'm unclear why it is necessary. Finally, how does one go about updating an existing document using the dictionary structure? My attempts have hit against the problem of the dictionary not being settable, even when defined with var.
great tutorial Brian!
Fantastic Tutorial! Thank you very much.
Hello. How would I go about implementing a feed that only shows “friends” or people the user is “following,” efficiently without duplicating data? Thanks!!
Cool. Better then Firebase))) Thank you.
Hey Brian..Your tutorials are very helpful to see the whole development process on these topics. The data nesting in Firebase seems different than what I am used to with SQL formats. Are you planning to do a tutorial with nested data in Firebase? Could you show us something maybe with users and their associated 'Sweets' as nested data?
Nice video! Is there any chance you could create a version for swiftUI?
Perfect Tutorial...
Hey Brian,
Thanks loads for this tutorial. Can you please show how to go from the table view to a detail view retrieving a document using document id form meta data?
Great work! Thanks
Hey thank you for this tutorial. It works like clockwork... can you show us on how to delete a sweet from the tableview or collectionview and more importantly from firestore... it seems that you need to delete with ID but i cant find how to get a sweet ID for deletion
Very Good Video, thank you sir, I was looking for the solution since morning final got your right guidance, thank you very much, please keep up the more good work. Thank You once again
Hi Brian! Amazing videoo. One question tho. Why do I get "Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value" when I add a new entry?? Please help
The same
at 09:00, using xcode 11, after creating the dictionary and protocol, I cannot initialize the structure. Xcode will not pull the parameters (i.e. name, content, timestamp)
not sure if this is because i'm using the latest version
Hi Brian, thank you so much for the tutorial. Really great! I have a question though. I don't understand why we need to do the protocol? Can we not do the initialization inside the struct? Why do it this way? Thank you.
im getting "Cannot find 'indexPath' in scope" error , i try to control drag the table but still wont fix it. any idea how to fix this issue
For some reason I actually imagined Jonah Hill teaching me this tutorial
Hi Brian, I'm having trouble implementing the code in line 33 at 19:26. This is for my final year university project. Is it possible to get in contact with you for some help?
Hello I enjoy watching your TH-cam channel.
But I’m having a problem with sort and search bar with my firebase data
hello Mr.Brian, i got a question regarding the firestore: within one application, can i use half of my database tables in old firebase realtime database, and half in new firestore, simply because they charged different by number of request and amount of data, if it is data heavy database i use firestore since is charged by request , and vice versa, can they interact or exchange data perfectly ? thanks
No
Could you please add that you post photos???
Can you make a video showing how to delete the "sweets" (really cute name) from both the array and the Firestore database?
Firestore looks really great, but I just curios, do we need firestore while we have a firebase database? Because it's looks the same for me. I mean, we have offline support on firebase database too for example. Btw thank you for this great video :)
Idk if you want the answer still, but Realtime Database and Firestore have their own advantages and disadvantages. You don't have to adopt it, but I find the syntax significantly more legible and easier to work with.
'self' used before 'self.init' call or assignment to 'self xcode giving me that error on the last line of code. anyone can help?
nice :)
I managed to get everything working with the exception of the real-time updates listener. It only updates if I switch the simulator off and build and run again. Any thoughts on where to look to fix?
All fixed I didn't call the checkForUpdates () function after loadData (). I was going through the tutorial so fast I missed it. Doh!
12:55 - why do you initialize ref with nil first?
Same reason he uses string interpolation when you just could use the variable name on its own. You might need to come back and change it in the future and doing it out like that makes it easier to change individual parts.
wtf happened at 1:49 haha
Thanks to you mate, this is going to be a secret now :) Just did some quick editing
hehe :D
