Can't install builds via TestFlight as of Xcode 6.3 build 6d570

Question

I'm archiving my builds like normal, selecting iOS device from the device menu, and clicking Product->Archive. Once the archiving finishes, I click "Submit to App Store" in the Organizer window.

After the app successfully uploads to iTunes Connect, I enable TestFlight beta testing and try to download it to my device, at which point I get an error message:

Unable to Download Apps

"[Your app] and 1 other application could not be installed at this time.

Done | Retry

Any ideas what's going on here? I also tried running the debugger on my device, which is now listed as an "ineligible device" in XCode, even though it's running 8.3 and my deployment target is 7.0.

这可能与此线程有关，请尝试此=> Xcode 6.xx中出现的“不合格的设备”部分

Updated 4 : for XCode 6.3 & iOS 8.3, if you have this problem, just go to Product > Destination to select your device. Even though it says your device is ineligible, it will still allow you to select it. If your iDevice version is >= target version, the build should work. It must be a bug for XCode 6.3 in debug with iOS 8.3 (thanks @einfach)

通过更新info.plist文件中的版本号并重建来解决。
