[Intro to iOS] : Twitter App about twitterapp

[timothy1ee]

Deepak, excellent work on this homework, nice job tackling the optionals. Hopefully, things with iOS are starting to come together for you. In the feedback below, I go through a checklist, and if things look good, I'll mention it to let you know you're on the right track, or I'll provide some feedback.

• TwitterClient and models look good. In production, there would be more validation to be robust to unexpected values, but in this homework it was fine to assume a well behaved API.
• You should move your assets to Images.xcassets.
• TweetCell looks good, good use of property observers, you can make the view properties private for more encapsulation.
• viewWillAppear shouldn't generally fire network requests. Instead, just reload the table data. If the data has changed, pass it back to the view controller locally. If you do need to do a network refresh, consider doing it when the app comes back from the background.
• In general Auto Layout constraints look good.
