【答】：
参考资料：（原文来自这里）
Difference between IPA and .xcarchive:
IPA is a zipped up Payload folder which has YourApp.app bundle. .app contains all your application resources like images, plist files, compressed nibs and the executable, CodeSigning resources,etc.
xcarchive contains your app and dsym files. .DSYM is required to desymbolicate your crash logs. Right click on saved .xcarchive and select show package contents to see what it contains.
