안녕하세요.

구현하신 관련 코드블럭 기재 부탁드려요.

유니티 프로젝트에 Objective-C를 위한 SwiftBrige를 구현하여 KakaoSDK 사용하였습니다.
앱 실행 또는 앱을 내렸다가 다시 올릴때 발생한다고 합니다.
(테스트 빌드에서는 문제 없이 실행되고 잇습니다)
미리 감사드립니다.

안녕하세요. iOS SDK 담당자입니다.

제공주신 로그를 확인했을 때 refreshToken 중 appKey가 셋팅되어 있지 않아 크래시가 발생되는 것으로 보입니다.

2.24.0 이후로 내부적으로 토큰 최신화를 하고 있어 앱 초기화 시 KakaoSDK.initSDK가 선제되어야 합니다.

제공주신 KakaoSDKBridge 내의 initSDK()가 AppDelegate나 SceneDelegate 때 초기화가 되는지 확인 부탁드립니다.

빠른 답변 감사합니다.

SDK초기화는 AppDelegate(didFinishLaunchingWithOptions)에 구현되어 있습니다.

앱이 런칭되고 약간의 시간이 지난 후에 crash되는것으로 추정되고 있습니다.

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    //[self registerBackgroundTask];

    [super application:application didFinishLaunchingWithOptions:launchOptions];

    NSString* key = @"LaunchWithRemoteNotification";
    NSDictionary* userInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
    if( userInfo != nil)
    {
        NSError* error = nil;
        NSData* jsonObj = [NSJSONSerialization dataWithJSONObject:userInfo options:0 error:&error];

        if( error)
        {
            [[NSUserDefaults standardUserDefaults] setObject:error.localizedDescription forKey:key];
            [[NSUserDefaults standardUserDefaults] synchronize];
        }
        else
        {
            NSString* str = [[NSString alloc] initWithData:jsonObj encoding:NSUTF8StringEncoding];

            [[NSUserDefaults standardUserDefaults] setObject:str forKey:key];
            [[NSUserDefaults standardUserDefaults] synchronize];
        }
    }
    else
    {
        NSData* data = [[NSUserDefaults standardUserDefaults] objectForKey:key];
        if( data != nil)
        {
            [[NSUserDefaults standardUserDefaults] removeObjectForKey:key];
            [[NSUserDefaults standardUserDefaults] synchronize];
        }
    }

    registerUpdateObserver();
    //[self scheduleBackgroundTask];
    //[self test];

    [bridge initSDK];
    
    return true;
}

제공주신 stackTrace 상에서 확인했을 때, AppLovin SDK가 swizzle 하여 네트워크 요청을 조정한 듯한데요.
AppLovin SDK를 제거하여 시도하여도 동일한 크래시가 발생하는지 확인 부탁드립니다.

7

라이브에서만 발생하고 있는 이슈이고 AppLovin SDK를 당장제거하긴 곤란하여.
일단 KakaoSDK버전을 2.23.0으로 다운그레이드 해보려고 합니다.
(2.24.0에서는 2.24.1 대비 crash빈도가 낮아서 일단 2.24.0으로 라이브 릴리즈 먼저 진행)

추가로 문의 있으면 댓글 달겠습니다.
도움 주셔서 감사합니다.
