Building Qt 5.15.11 open source for IOS with Xcode 15 fails

Trying to build QT 5.15.11 open source for IOS with xcode 15 fails during configure on a freshly extracted archive:

sudo ./configure -platform macx-ios-clang -opensource -confirm-license -skip qtwebengine -debug-and-release -nomake examples -nomake tests -no-openssl -securetransport -prefix /usr/local/Qt-5.15.11-IOSK

results in:

Tried

sudo ./configure -platform macx-ios-clang QMAKE_APPLE_DEVICE_ARCHS="x86_64 arm64" -opensource -confirm-license -skip qtwebengine -debug-and-release -c+std c+14 -nomake examples -nomake tests -no-openssl -securetransport -sdk iphoneos -prefix /usr/local/Qt-5.15.11-IOSK

with the exact same results.

Any idea how to fix?
