Unable to execute command: killed 9 in Xcode 9.3 - ios

Question

I have a unity project that i'm building for iOS. I've included EasyAR, OneSignal, Firebase Analytics in the project.
It is working fine on Android without ant hiccups.
But on iOS I get this error in Xcode:
clang: error: unable to execute command: Killed: 9
clang: error: clang frontend command failed due to signal (use -v to see invocation)

Answer 1

i met the some problem and solve it
with c# code
public class SomeWord
{
public static List<string> Words = new List<string>(new string[]
{
"aaa"
, "bbb"
, "ccc"
, "ddd"
, "eee"
, "fff"
, "ggg"
// the list has 3w ele
il2cpp convert this to
extern "C" void SomeWord__cctor_m3830774958 (Il2CppObject * __this /* static, unused */, const MethodInfo* method)
{
static bool s_Il2CppMethodInitialized;
if (!s_Il2CppMethodInitialized)
{
il2cpp_codegen_initialize_method (SomeWord__cctor_m3830774958_MetadataUsageId);
s_Il2CppMethodInitialized = true;
}
{
StringU5BU5D_t1642385972* L_0 = ((StringU5BU5D_t1642385972*)SZArrayNew(StringU5BU5D_t1642385972_il2cpp_TypeInfo_var, (uint32_t)((int32_t)26109)));
NullCheck(L_0);
ArrayElementTypeCheck (L_0, _stringLiteral1002530778);
(L_0)->SetAt(static_cast<il2cpp_array_size_t>(0), (String_t*)_stringLiteral1002530778);
StringU5BU5D_t1642385972* L_1 = L_0;
NullCheck(L_1);
ArrayElementTypeCheck (L_1, _stringLiteral632527236);
(L_1)->SetAt(static_cast<il2cpp_array_size_t>(1), (String_t*)_stringLiteral632527236);
StringU5BU5D_t1642385972* L_2 = L_1;
NullCheck(L_2);
// this style of code repeat nearly 3w times
just pick out the string in list and put it in a file, then read in from file solve the problem. the c# code is auto generate with some reason maybe i don't know why. next time if someone meet the same problem, do with this step:
1) check out the xcode compile step and find out which file cost a lot of time
2) open the file and find if there is some weird function with a lot of statement in
3) find out which c# file convert to those code and change it
