March 27th is the deadline to submit your new iPad application if you want it to be in the app store the for iPad launch date, April 3rd.
I took some notes during TUAW’s Dev Clinic discussion on the process to compile your app and upload it to iTunes:
- Application Target
- Make sure you are using the “release” configuration, and not “debug”
- Base SDK: iPhone Device 3.2 (or 3.1.2 or 3.1.3 for Universal)
- Architecture: armv7 (you’ll have to select “other” and type this in)
- … for a universal app select “armv6 armv7″
- Code signing identity: Distribution
- Targeted device family: iPad (unless you are doing Universal)
- Deployment target: “iPhone OS 3.2″ for iPad-only, “iPhone OS 3.1.x for Universal”
- Icons: use a 72×72 icon (not 48px as some have said), you may or may not want to include a 57×57 icon
- Signing and Uploading
- Set your configuration to “Release” in the Target Info window and in the Project window
- Compile for the device, not the simulator
- trash your previous builds (the entire build folder, even!)
- double-check your code-signing identity, update your distro provision if necessary
- after you compile, locate the binary using Products < [app] < Locate in Finder
- zip up the app and submit it to apple
