Xcode 8.2.1 falha ao abrir o projeto com o índice de matriz fora dos limites

Acabei de atualizar para o Xcode 8.2.1 e o Xcode trava toda vez que abro meu projeto com o seguinte rastreamento. Eu verifiquei que uma versão mais antiga do Xcode (8.1) ainda pode abrir o arquivo do projeto. Qualquer ajuda seria muito apreciada.

Exception Type:        EXC_CRASH (SIGABRT)
Exception Codes:       0x0000000000000000, 0x0000000000000000
Exception Note:        EXC_CORPSE_NOTIFY

Ok, consegui corrigir esse problema excluindo meu diretório .xcworkspace e recriando-o via pod install. O Xcode é aberto e eu consigo criar meu projeto.

Editar : como outros sugeriram, uma solução melhor é excluir o diretório xcuserdata de dentro do .xcworkspace. Isso é mais rápido, pois você não precisa executar novamente a instalação do pod toda vez.

A resposta correta é do comentário de Lukasz :

1. Clique com o botão direito do mouse no arquivo .xcworkspace> Mostrar Conteúdo do Pacote
2. Excluir a xcuserdatapasta

E agora o Xcode abrirá bem a área de trabalho do projeto.

Para outras pessoas que enfrentam um problema semelhante, mas isso só acontece quando o Find Navigator é alternado na área do navegador. Tente clicar no Project Navigator ou CMD + 1repetidamente após o lançamento. Parece engraçado, mas funciona.

Além de excluir a xcuserdatapasta no diretório da área de trabalho do projeto, também pude remediar essa falha em particular, excluindo dados derivados (para o projeto que estava aberto enquanto o Xcode travou ou para todos os projetos) em ~/Library/Developer/Xcode/DerivedData. A última vez que o Xcode caiu, eu tive que fazer as duas coisas para poder iniciar o Xcode novamente, então acho que excluir as duas é a sua aposta mais segura (pelo menos por enquanto).

• sim excluir xcuserdata ajuda.
• Eu costumava limpar os Dados Derivados, mas eles travavam novamente imediatamente no Reopen se eu tentasse fazer alguma coisa antes de a indexação terminar novamente.
• Percebi que isso só aconteceu em um projeto pessoal que editei em casa e no trabalho.
• O nome de usuário era diferente nos dois, então acabei com duas entradas de usuário no xcuserdata: meu nome de usuário de login do trabalho e meu nome de usuário residencial.
• Percebo que ambos têm pontos de interrupção.
• E o erro gerado é _IDENavigatorOutlineViewDataSource, então é algo nos painéis laterais do LHS no Xcode?
• Você pode adicionar um .ignore para xcuserdata sem atrapalhar um espaço de trabalho?
