New Test App Build on iTunes 10 Won't Install

Question

I have been developing test builds of an app for some time and have deployed through iTunes successfully until now, with iTunes 10.

At the same time I am getting a strange warning in Xcode during the build. It is:

• warning: building with 'Targeted Device Family' set to iPhone only ('1') not supported with SDK 'Device - iPhone OS 3.2'.

My target SDK is 3.1.3, base is 3.2. If I change the base to 4.0 the warning goes away. In either case the app's .ipa is recognized by iTunes, accepted, asks if I want to replace the existing app in iTunes. BUT, a synch does not move the app to the device, without any error or warnings.

Any help greatly appreciated.

Answer 1

SDK 3.2 if for iPad development (or for Universal apps). For iPhone only use 4.0 (or maybe 4.1 tomorrow).

Answer 2

At some point iTunes has started requiring that the bundle version number be increased from the installed app. Once I started doing this in the info.plist of the app, the installation proceeds as expected.
