Invalid bitcode signature while building in Xcode - ios

Question

I am trying to build a very old iOS Cordova App.
It builds successfully for Simulators but, when I try to build for any real hardware, it shows error:

error: Invalid bitcode signature clang: error: linker command failed
with exit code 1 (use -v to see invocation)
I even tried using Xcode 7, 8 and also 9 but, I still get the same error.

Answer 1

Try:
Clear derived data and then reopen Xcode.
Select proper sign in / certificate, or try to re-add account in Xcode.
Make sure if your pods supported bitcode if not then you need to set bitcode to NO (Go to Project Build setting search for bitcode & set it to NO.
Or trying this may help you:
OR
Open Podfile
Uncomment this line ~> platform :ios, 'x.0'
From the command line run the following command where Podfile resides
pod update
In the xcode select Product > clean and then Product > Build

Answer 2

I encountered this error before..
Try this solution:
Go to Build Settings > Build Active Architecture Only
Make changes on the selected target
a) Set it as 'YES' if you're building/pushing the app directly to a device
b) Set it as 'NO' if you're trying to build the app as IPA
Hope it helps!

Answer 3

Go to project > targets > general > deployment info. Make sure your deployment target is same as your hardware's ios version
