resources or a third party resource:
– Design patterns
– Licensing
– Device compatibility

12. Design patterns:
• Many of the frameworks use well‐known design
patterns for implementing your application.
• For example, the Model‐ View‐Controller (MVC) design
pattern is very common.

13. Licensing:
• Understanding

• Be aware of

might enforce.

14. Device compatibility:
• Writing an application for one device doesn’t mean it
will automatically run or behave the same on another
y
device.
• Take some time to understand
– the constraints

– and differences, and design your application for a multi‐device
scenario, if applicable.
• For example, the iPad has more real estate that an
iPhone.
