I'm pretty sure both IDEs just forward clang's findings to you. When I put the 
above function in my (C++) project, Creator's clang static analyzer showed me 
the exact same message you pasted above.

Hi, great that you were able to use Qt Creator for that!

A few notes:

QMake has a separate variable for Objective-C/++ sources called  
OBJECTIVE_SOURCES. Not sure if it makes a difference in Qt Creator though (or 
if we only care about the file extension).


I checked, seems OBJECTIVE_SOURCES or SOURCES work the same in my .pro 
file for the purpose of Qt Creator's syntax highlighting and code 
completion/IntelliSense.




I suppose you can get rid of your INCLUDEPATH and links if you set the Sysroot 
in your kit to 
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk



Yes I could get rid of them! But the answer was actually much simpler, I 
had forgot to install Qt 5.10.1 for iOS, only had it for "Desktop" on my 
desktop Mac. Once I've installed iOS support, removed the old .pro.user 
file and started anew with "Qt 5.10.1 for iOS Simulator",
#importing  works like a charm without any ln -s helper 
links :-)



One more question: for all the Xcode bashing, I find the Analyze compile 
command in Xcode more powerful/finding more stuff than the Analyze/Clang 
Static Analyzer in Qt Creator. For example, if I have this simple 
function in my .mm file:


void xyzzy()
{
int i = 42;
int i2 = i + i;
i = i2;
}

Qt Creator's Analyze is happy with it but Xcode's Analyze says "Value 
stored to 'i' is never read" for the "i = i2;" source line. Would be 
nice if Qt Creator could have the same power :-)
