错误“Thread 1:EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)”是什么意思？
what does Error “Thread 1:EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)” mean?
我尝试在模拟器中构建时出现错误
dyld_sim`dyld_fatal_error:
0x101799000 <+0>: int3
-> 0x101799001 <+1>: nop
说明有导致崩溃的指令，比如强行解包不存在的东西，得到的值为nil。
Take a look through your code and see if there are any situations where you force unwrap something that does not necessarily exist.
