最后我才弄明白这是一个pod问题...只需弄清楚它是哪一个。

At long last I was able to figure out this was a pod issue...just had to figure out which one it was.

我创建了一个全新的项目并开始逐个添加我的pod（实际上，3个3 ...一个接一个地花了太长时间。）

I created a brand new project and started adding my pods in one by one (actually, 3 by 3...one by one would have taken too long).

结论：localytics 4.3.1在某个地方有一个错误。我降级到4.3.0，问题就消失了。

Conclusion: localytics 4.3.1 has a bug in it somewhere. I downgraded to 4.3.0 and the problem went away.
