Great!! Already looking forward to the search capabilities and the way how you refactor your code thru the whole project. Excellent learn today!

Thanks alot for working so hard to produce these videos. Looking forward to the search video

Hi, Brian. Want to give you another thank for the tutorial and ask another question. :] With Swift 3 out there was introduced Grand Renaming. What do I mean? I mean all those methods like fetchPostWithUser(user: User). It's name is long and the word user repeats a lot of times. With Grand Renaming this function should look something like fetchPosts(for user: User) What do you think about it?

Hey Brian, Love your vids and appreciate your time and commitment. I am having an error every time I click onto the User Tab. The app keeps crashing and I get this message. Would you mind deciphering this for me? Thanks! objc[96638]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x1204e6998) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x120308880).

Thank you for using Extension and Completion Block and I should review more further this to Apple Doc's

i just wanted to say THANK YOU Brian i know recording these videos takes a lot of time and efforts, i ve learned so much on how to refactor code specially using firebase....

Hey Brain, I am not sure if you have shown how to automically update home feeds when we post a photo without reopen the app? If yes, could you please tell me where it is

Everytime the collectionview reloads the collectionviewcells, it shows mine first and then all the other users (creating a ugly flickering). Your project works but mine doesn't (even after copying your code).. I have no idea what else to do. Please help!

Brian, the refactoring with Firebase extension and completion is poetry to me. I really enjoyed it, thanks!

I don't know what should to say to describe about how useful this lesson series is. I've self-learnt Swift programming for 1.5 years and I learnt more in this lesson series than everything else combined from elsewhere. Specifically, the use of completion block, eliminated my confusion that had been existing all times. Brian, thank you.

Are there any direct resources going into depth on retain cycles that you suggest besides googling/stackoverflow? I feel like there are quite a few concepts I need a further understanding of to become a more competent iOS Developer. Where did you pick up on these more advanced topics?

Damn that was so crispy

Currently finished the app up to this episode. Man, I loved the fetchUserWithUID refactoring part. I appreciate this kinda deep knowledge tips and bits a lot. Thanks. This project course deserves more than its price.

Hey Mr. Voong, I was wondering if you had any information on, how to stop a collection view blinking on reload data() I setting the cell content to nil, before assigning a new post object, because it is recycling the cell's and giving it the previous cell's content before the async is complete for this cell that is being rendered.

Yet another excellent video Brian! One thing I'm wondering about is why the static func is an extension on FIRDatabase instead of the "User" class itself. I'm very new to all of this and I was under the impression these kinds of methods would usually be tied to the object type, so that if the data source changes in the future, the code structure isn't tied to old/previous data source references. Was this approach used to keep things simple in this lesson or is this the standard approach you would take? Any other thoughts or advice to help bring clarity to this for me? I appreciate it!

Awesome stuff!!

Hey Brian, a quick note. In the profile controller you have you insert every new post at the index of 0, but in the home controller you append the post. My question is do you need to insert the post at the index of 0 as well or not. Thank you

Hey Brian, do you know why sometimes the scroll doesn't keep scrolling while finger up on a UIImageView?
