Xcode error Thread 1: EXC_BREAKPOINT (code=1, subcode=0x1001f276588)
提问by atirit
I get the titular error when running my project on an actual device. Sometimes the subcode varies. I don't have ANY breakpoints. I checked. Trust me on that.
在实际设备上运行我的项目时出现名义错误。有时子代码会有所不同。我没有任何断点。我检查了。相信我。
Here are my files. This error happens on launch.
这是我的文件。此错误发生在启动时。
What can I do to fix this? Thanks in advance!
我能做些什么来解决这个问题？提前致谢！

I think the error is in this part:
我认为错误在这部分：
let dir = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first
let filePath = NSURL(fileURLWithPath: dir!).URLByAppendingPathComponent("file.txt")
It is forced to unwrap "dir", which is probably not available in this case on your actual device. This causes the immediate crash.
它被迫解开“dir”，在这种情况下，这可能在您的实际设备上不可用。这会导致立即崩溃。

I found the problem: I was trying to use a variable that was nil. I know that's what the debugger message says, but I figured out which one.
我发现了问题：我试图使用一个为零的变量。我知道这就是调试器消息所说的，但我想出了哪个。
Oh well. I messed up. Thanks to everyone for all their help!
那好吧。我搞砸了。感谢大家的帮助！
