4. Tram Times
• Add your favourite stops to the app to access the tram times quickly.
• Departure message board for the latest information on your tram line.
• Quickly access your first stop using the Today Widget.
• Quickly access your saved stops using 3D Touch.
• View the latest tram times for your saved stops on your Apple Watch.
Data is realtime and updated live direct from Metrolink.

5. 1. Ideas
• Lots of half started projects
• Set yourself a month -
• 2 weeks of development days
• 40 hours of development
• Get it into the hands of users early
yes this is another 10 tips to the app store talk
considerations when working at a short time scale
development tools
Whose Xcode project looks like this
set a month for your idea to mvp
get it into the hands of users
some tips on getting to the app store

6. 2. Maintainability
Lots of different app architectures, MVC, MVVM-C
SRP
The Single Responsibility Principle (SRP) states that each software module should have one and only one reason to change.

7. Coordinators
http://khanlou.com/2015/10/coordinators-redux/
Each view controller is now isolated.
View controllers are now reusable.
Every task and sub-task in your app now has a dedicated way of being encapsulated.
Coordinators separate display-binding from side effects.
Coordinators are objects fully in your control.

8. Refactor

9. 3. Frameworks
Adapters
https://www.raywenderlich.com/126365/ios-frameworks-tutorial
Wrap your dependencies in frameworks
Hexaganol
Protection from change
Tram api changed
I want to use something other than user defaults
Judgement call on system frameworks
Easier for re-use

10. 4. App Extensions
Today Extension
Imports Station request framework, feature without much effort
Home screen quick actions
3D Touch
Messages
Spotlight Index

11. 5. Testing
• Don’t
• Spend time writing features not tests
• Now I have some users I will spend 2
months writing tests to stop regression
• On any other project TDD :-)
• http://codingdojo.org/kata/Bowling/
Don’t test
spend time writing features not tests
will probably spend the 2 months after testing

12. 6. WatchKit
• WatchKit very different to UIKit
• Different container, User Defaults
• OS Changes
• Need to create a watch specific framework
Took a long time
WatchKit different to UIKit
Complications

13. 7. Tooling
- Limit dependencies
- 10 minute commits
- Cocoapods
- Icons 8
- CircleCI
- http://appreviewtimes.com/ https://icons8.com/
Github - 10 minute commits, Bitbucket
Circle CI
Limit dependencies
Don’t use AFNetworking, URLSession, Decodable
https://github.com/AFNetworking/AFNetworking
Cocoapods over spm or carthage

14. https://firebase.google.com/docs/ios/setup?authuser=0
- Firebase
- Crashlytics
7. Tooling
All much of a muchness
Big push on analytics
No deployment yet
Nice features for push notifications

15. 7. Tooling
https://fastlane.tools/
- Snapshot
- frameit
- Deliver
Fastlane build automation tools
Snapshot -> Demo
Deliver
bump version numbers

16. 8. Testers
• Annoy people at work
• Use Hockey or TestFlight

17. 9. Accessibility
- VoiceOver Support
- Settings -> General -> Accessibility -> VoiceOver
- Accessibility Inspector
