Mobile App Size on Apple APP Store with Bitcode Enabled

Question

I am new & try to have my First application on App Store.
I have made this app in UNITY (5.6).
The issue I'm Facing is the size of Archive generated by Xcode (8.3), which I have to upload on App Store and is over 100 MB while the same APP on Play store (.apk file) is only 31 MB. See the details Below :
For Android its ~ 31 MB (Approx).
And for iOS its like : Archive Unity-iphone FILE NAME and File Structure:

- Unity-iphone 29-07-17, 10.25 PM.xcarchive : 630.50 MB
After Unpacking IT :
    -- BCSymbolMaps :
       --- 778F6F4C-6E2D-3192-BAY9-FEBDFA98EF0E.bcsymbolmap : 12.8 MB
        --- B3746668-8893-3427-A5AB-9741BE4B62B3.bcsymbolmap : 12.9 MB
    -- Unity-iphone.app.dSYM : 138 MB
    -- Unity-iphone : 467 MB
    -- info.plist

As I searched internet, All are saying to make .IPA File to have estimate of AppSize on App Store. So I exported .IPA File (3 Variants)

• Unity-iphone.ipa (With Bitcode And dSYM Enable) : 163 MB
  
• Unity-iphone.ipa ((With Bitcode Disable And dSYM Enable) : 55.2 MB
  
• Unity-iphone.ipa (With Bitcode And dSYM Disable) : 24.4 MB
  
  So please tell me which one to upload to App Store.
  AND if (with bitcode and dSYM disable) I have to disable it in build settings ( Enable Bitcode to NO and Debug info. format release to DWARF only ) and compile the project again and make archive again OR Just while uploading archive toApp Store, I uncheck both options.
  
  Please help as I am doing it for the first time and it matters as there is huge differences in File sizes.

The bigger is the better for your case.

• DSYMs files will let you have more informations if you app crashed in the future
  • not in the final .ipa of the client
• Bitcode files will let Apple recompile your app and regenerate .ipas available on the store if they improve compilation, or for example a future architecture you didn't compile for.
  • not in the final .ipa of the client

Upload it, and you will see, in Testflight section (iTUnesConnect -> Your App -> Activity -> All Builds (left panel) -> Your build -> AppStore Size link), the real size of your app for each iPhone/iPad. for example i uploaded a 150Mb size bundle, and finally, the .ipa size for iPhone 7 is only 40Mb.
