FIRMessagingDelegate can not find declaration

[atayuksel]

When I try to declare FIRMessagingDelegate in app delegate Xcode gives an error "Cannot find protocol declaration for FIRMessagingDelegate".

I imported firebase as implemented in the project

#import <UIKit/UIKit.h>
#import <UserNotifications/UserNotifications.h>
#import <MessageUI/MessageUI.h>

#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
@import UserNotifications;
#endif

@import Firebase;
@import FirebaseInstanceID;
@import FirebaseMessaging;

@interface AppDelegate : UIResponder <UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate>

I imported firebase via cocoa pods and response is
Installing Firebase 3.2.1 (was 3.2.0)
Using FirebaseAnalytics (3.2.0)
Using FirebaseInstanceID (1.0.6)
Using FirebaseMessaging (1.1.0)

Everything seems fine but I could not solve the problem anyway? What could be reason for the problem?

I updated the cocoapod version (had 0.39.0) and now 1.0.1...

check version by entering: pod --version

then install the newest version with: gem install cocoapods

Now I updated pods, It works well, thanks 👍

"pod update" solved the problem. Thank you!

I already have pod version 1.0.1 but yet I get the same problem. How to solve it

@MaxBerny After updating to cocoapod version 1.0.1 ,
run pod update, it will solve your problem.

How can you update to 1.0.1? 1.1.1 is the latest version.

[Benjaminm5]

1.1.1 should work! 1.0.1 or newer... Am 27. Dez. 2016, 21:03 +0100 schrieb Iulian Onofrei <notifications@github.com>:

Although I updated the pods the problem remained. I fixed it by moving @import Firebase; @import FirebaseInstanceID; @import FirebaseMessaging; above the interface declaration (it was below by mistake)

i tried all the suggestion still not working 😞. i am on pod version 1.1.1 and even if i go into Xcode doc of messaging() i didn't find the "remoteMessageDelegate".

Actually this was my mistake, as i was migrating from GCM to FCM, first i need to remove the GCM framework and i have to add FCM. but i was adding FCM on top of GCM so i got into an state where i was facing duplication issue with one the class which in both GCM and FCM. while resolve it podfile.lock was acting very weird and this is the reason for mess.

In my case,I've tried to update the pod and it failed.Then I deleted the podfile.lock and run pod install** It finally works!
