How to check the iOS SDK version used to compile .ipa or .app file

Question

I have just the .ipa files (I don\'t have the build env) without any access to the project. I\'m trying to determine if they were built linking SDK 7. Is there a way or util

Answer 1

There is another way to do it: open Info.plist

plutil -p Payload/APPNAME.app/Info.plist | grep DTSDKName

That gives you result like:

"DTSDKName" => "iphoneos7.0"

P.S. This way works for very ancient apps too.
