Summary:
If you build an app with only 32 bit support and then run on a 64 bit device like a 5s and use MFMessageComposeViewController together with a UIEdgeInsets appearance setting the MessagesViewService will crash.

Steps to Reproduce:
1. Build included test app
2. Run on 64 bit device

Expected Results:
Should show MFMessageComposeViewController

Actual Results:
Does not MFMessageComposeViewController and MessagesViewService crashes.

Version:
iOS 7.0.3

Sample app:

AppDelegate.h:
#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@end


AppDelegate.m:
// Compile with armv7, arm7s etc but exclude arm64. Then run on 64 bit device like 5s.

// MFMessageComposeViewController seems to be a remote view controller handled by
// MessagesViewService. The UIApperenace settings are replicated over to MessagesViewService
// but there is some kind of mismatch for UIEdgeInsets apperance proprties.
// MessagesViewService runs as 64 bit i guess.

// app log:
// init Error Domain=NSCocoaErrorDomain Code=4097 "The operation couldn’t be completed. (Cocoa error 4097.)"
// Remote compose controller timed out (NO)!

// console log:
