我相信这个问题是一些相当明显的，但我只用斯威夫特工作了3个月，这是我的第一个编程语言。我真的很感谢帮助。
谢谢你的时间。
同样的错误
嗨，我已经尽我所能这种自己，但不能去抓住它。 @Vadian最初的回应解决了IBActions的问题后，我仍然收到相同的SIGABRT错误。
错误信息
2016-10-06 17:18:33.709206 Truegram[13130:1026640] [MobileAssetError:29] Unable to copy asset information from https://mesu.apple.com/assets/ for asset type com.apple.MobileAsset.TextInput.SpellChecker

我觉得上面是最相关的错误，这似乎与按“签署”
我还增加了一个后发生错误平反注册页面，具体针对可能导致该问题的企业。

你能帮助我们一点，并指出错误是什么行吗？编译器指出什么？ – KSigWyatt
点击按钮时会出现错误吗？ –
