7. Objective-C
• Why use Objective-C?
• Last year Swift was not yet
mature
• Legacy code was still in Obj-C
• No point switching to Swift
8.
9. CocoaPods
• Has a huge library of supported
components
• But tends to break when new
version of Xcode is released
• Am looking into alternatives e.g
Carthage
10.
11. Parse
• Only for push notifications
• Easy to set up and test
• Tried Urban Airship, but had
problem with missing push
notifications
• Parse has not failed us. YET!!!
12. Private Chat/Group Chat
• Firebase for Chat
• Firebase good for real time use
cases
• Chat is 1 of them
• But Firebase is not dedicated for
chat
13. Private Chat/Group Chat
• So additional chat functionalities
such as image upload is not
supported
• It was a hassle managing data
from between our DB and
Firebase
14.
15. Private Chat/Group Chat
• Switched to Layer
• But as with all cutting edge tech
• Code examples do not work out
of the box
• 50% of their sample code have to
be modified
16. Private Chat/Group Chat
• Layer is developed purely to
create chat apps
• So image upload, video upload is
all supported
• But can be a bit slow at time

18. AFNetworking
• Most popular iOS networking
library we have seen so far
• Widely used
• Widely supported
• But still have issues
19. AFNetworking
• Issue due to Apple’s NSURL
implementation
• Causes operation time outs even if
network is ok
• https://github.com/AFNetworking/
AFNetworking/issues/2314
20. AFNetworking
• Also sometimes we have multiple
alertviews about network errors
• Anyone encountered such errors
before?
21. Backend
• Typical LAMP stack
• PHP as fast to get going
• MySQL as it is the standard
• Running on Linode
• Ubuntu 14.04
