Xcode 7 TwitterKit warning

[alxvasenin]

@bonnell No, neither cleaning nor deleting DerivedData does not clears it up.

Thanks for letting me know @alxvasenin, can you share your current Fabric init? Are you using components outside of Twitter Kit?

Here’s my current setup that I can’t reproduce this on:

#import "AppDelegate.h"
#import <Fabric/Fabric.h>
#import <TwitterKit/TwitterKit.h>

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    [Fabric with:@[[Twitter class]]];
    return YES;
}

@bonnell We also use Crashlytics:

[Fabric with:@[[Crashlytics class], [Twitter class]]];

I think those warnings can’t be related with the way we init or use Twitter, since they are generated at compile time, and not at runtime. Have you tried to purge ~/Library/Developer/Xcode/DerivedData ?

@bonnell If I simply add those line to TwitterKit.framework/Headers/TwitterKit.h it solve 2 out of 3 warnings:

#import "TWTRDefines.h"
#import "TWTRShareEmailViewController.h"

However, if I add TWTRSession.h to the same place it refuses to compile with error "Duplicate interface definition for class TWTRSession", because it’s defined both in TwitterKit.framework/Headers/TWTRSession.h and TwitterCore.framework/Headers/TWTRSession.h.

Hey @alxvasenin,

Thanks for the extra info and I have cleared Derived Data.

Then running a build or clean and build produces no warnings.

Very strange that we’re seeing different behavior on this, still want to track this down.

I am still experiencing these warnings in Xcode 8.0. Neither cleaning nor clearing DerivedData resolves the issue.

TwitterKit.Framework: ???
TwitterCore.Framework: 2.5.0
Fabric.Framework: 1.6.9
Crashlytics.Framework: 3.8.2

Any update on this issue?

@JaronLowe1 I unfortunately still haven’t been able to reproduce. Do you have a sample project or slimmed down version of your project that you can share to make reproducing this easier?
