Getting an app ready for day one of an iOS/device launch is impossible to do right. As a developer you have a variety of options available for how you approach it, none of which are perfect.

Trade Offs:

• App Review
• Marketing (good and bad)
• Bugs and Issues
• Helpdesk load
• New features and their worth
• Wasted effort

Approaches:

• As ready as you’ll ever be: Work feverishly, battling through buggy betas and API changes to be as possibly ready as possible for the estimated release date.
• Measured compatibility: Just make sure it doesn’t break
• Kinda ready: Keep an eye on the changes, have plans in place for basic compatibility begin in earnest once bugs are fixed
• Wait and See: Wait until you have all the information before you really start
