[Interest] iOS release build uncount issues - implicit conversion loses integer precision

On 64 bit systems that piece of code does pointer1 – pointer2, which would be a 64 bit value, then implicitly doing a narrowing cast since the function returns an int (32 bit value on your arch).
Anyway, fastest fix is probably to just disable the shorten-64-to-32 warning in the release kit or compile for a 32 bit target.

Subject: [Interest] iOS release build uncount issues - implicit conversion loses integer precision
debug build and run works well
but release build I'm getting thousands of issues like this one:
/daten/_qt_sdks/sdk_590/5.9/ios/include/QtCore/qvector.h:841: warning: implicit conversion loses integer precision: 'long' to 'int' [-Wshorten-64-to-32]
return n - d->begin();
any idea what could be wrong ?
* Qt 5.9
* Xcode 8.3.3
* iOS device 10.3.2
* macOS 10.12.5
* Creator 4.3
