ios - App Store Team error saying "your app contains bitcode" after application submission -

i've never heard of term bitcode before @ , don't know start looking around on how fix issue.

i using xcode 7 beta 3 , i've uploaded app 3 times every time upload it, change status invalid binary

i got email app store team saying

"invalid executable - executable 'esuhsd.app/esuhsd' contains bitcode."

i don't know information need know app hoping appreciated!

first of all, don't think can submit any release apps built with beta version of xcode (even if target existing ios / watchkit sdk combination).

as far "bitcode", go developer.apple.com , take peek @ wwdc videos on "app thinning", relevant documentation next release.

for submitting app beta testing, story. in general, that's possible, there may quirks; answer @jan covers specifics xcode 7 beta having bitcode.

for references saying not submit release apps appstore beta xcode versions, see following posts (if come definitive docs apple, great add link):

from apple developer forums, accepted answer never can submit using beta xcode, , multiple people state you've never been allowed submit using beta software. there 1 section mentions workaround regarding bitcode , submissions, suggested after xcode 7 released formally: apple forum: can submit app store app built xcode 7 long not targeting ios 9?

from stackoverflow: accepted answer concurs submitting apps using beta xcode forbidden: workaround submit app app store xcode 7

from stackoverflow: "app needs compiled release version of xcode" accepted answer: submitting ios app using beta version of xcode?

additionally, apple technical document on submitting app store says should use latest xcode , sdk -- don't mention beta vs. release, link "latest" goes latest release version of xcode, available via mac app store. see technical q&a qa1806: version of xcode , sdk should using when building app store?

note: edited based on op's stated intent in comment beta testing, not release build prior sdk.
