Issues updating Phonegap iOS app for 64-bit architecture - ios

Question

I have a phonegap app with many plugins that runs fine on iOS devices. However, I am currently using $(ARCHS_STANDARD_32_BIT) for architectures in xcode, and now believe I need to update it to be $(ARCHS_STANDARD) in the architecture setting and to include arm64 as a valid architecture per Apple's Feb 1, 2015 requirements.
When I try to run the project on an iPhone 6, I get 16 errors now, copied below. 2 questions:
1) Do I need to use the archs_standard and arm64 changes mentioned in the 1st paragraph?
2) How do I fix these issues so I can submit my app? Is it all issues with individual plugins I'm using? Do I need to find an updated version (or update myself) every plugin listed in the errors or is the issue related to something else? I don't see updates for 64-bit on a few of the plugins I've looked at, so not sure if this is what the issue is. I'm not very familiar with Obj C so appreciate any help here!
Thanks in advance for any help!

Answer 1

1) Do I need to use the archs_standard and arm64 changes mentioned in
the 1st paragraph?
Yes, you have to use $(ARCHS_STANDARD) and arm64 if you want to submit the app to the stores.
2) How do I fix these issues so I can submit my app? Is it all issues
with individual plugins I'm using? Do I need to find an updated
version (or update myself) every plugin listed in the errors or is the
issue related to something else? I don't see updates for 64-bit on a
few of the plugins I've looked at, so not sure if this is what the
issue is. I'm not very familiar with Obj C so appreciate any help
here!
The plugins are fine, the problem is the cordovaLib project. You have to change the cordovaLib project to $(ARCHS_STANDARD) too and rebuild the libCordova.a, or even better, use a cordova version greater than 3.4 that will include the 64 bits support.
EDIT:
More details from the link manihiki provided:
You will need to update the Build Settings in your project. The steps are mentioned in the issue and reproduced below:
//Update build settings for your project
Select your Project icon Choose Build Settings.
For “Architectures”, select $ARCHS_STANDARD – Standard architectures (armv7, armv7s, arm64)
For “Valid Architectures”, add “arm64″
//Update build settings for cordovaLib project
Select your CordovaLib.xcodeproj icon
In the Build Settings for the Project (not Target), delete *all* the conditional architecture settings (hover to see the minus sign). This is what is recommended by Apple in their Xcode 5.1 Release Notes.
For “Architectures”, select $ARCHS_STANDARD – Standard architectures(armv7, armv7s, arm64)
For “Valid Architectures”, add “arm64″
//Update build settings for the Target
In the Build Settings for the Target, delete *all* the conditional architecture settings (hover to see the minus sign).
For “Architectures”, select $ARCHS_STANDARD – Standard architectures (armv7, armv7s, arm64)
For “Valid Architectures”, add “arm64″
Some plugins might not work, you have to made this changes
On CordovaLib/Classes/CDVCommandQueue.m
change this
objc_msgSend(obj, normalSelector, command);
to this
((void (*)(id, SEL, id))objc_msgSend)(obj, normalSelector, command);
and on CordovaLib/Classes/CDVViewController.m
change this
if ((BOOL)objc_msgSend(plugin, selector, request, navigationType) == YES)
to this:
if (((BOOL (*)(id, SEL, id, int))objc_msgSend)(plugin, selector, request, navigationType) == YES)

Answer 2

I inherited a legacy PhoneGap/Cordova app and received many similar errors when changing the Architecture Build Setting to $(ARCHS_STANDARD).
I was able to successfully build after updating (removing and then adding) two PhoneGap plugins (out of nine total), and removing/adding the PhoneGap iOS platform each time. Specifically, the plugins were com.phonegap.plugins.barcodescanner and org.apache.cordova.geolocation. I targeted those two plugins by googling the classnames in the errors and determining which plugins they related to.
To "update" a plugin:
cordova plugin rm com.phonegap.plugins.barcodescanner
cordova plugin add com.phonegap.plugins.barcodescanner
To remove/add the PhoneGap/Cordova ios platform:
cordova platform remove ios
cordova platform add ios
