@obigu this issue was that new xcode is ignoring that flag. When building with xcodebuild to build the audio backend it was overriding it to latest for the system, 14.2. jnigen was fine when i looked at it, (it does not use xcodebuild to generate natives), and no warnings for versions in logs

@cellcrowd Ok, good news, feel free to close the issue, I’ll keep banging my head against the wall to try to understand what’s wrong with my env.

I think the culprit has to do with the fact that we have migrated to gdx-jnigen to build natives and -miphoneos-version-min was being set to 6 instead of 8 which was causing problems. (https://github.com/libgdx/gdx-jnigen/blob/f9be183adefb5fe9c8917a1b83bc7f9cc8961200/gdx-jnigen/src/main/resources/com/badlogic/gdx/jnigen/resources/scripts/build-ios.xml.template#L87)

@Tom-Ski Thanks for the fix.

Had to wait an eternity for Xcode to update from 12 to 12.4, just to confirm that not be an issue

Refreshed snapshot/gradle, cleared cache, compiled, and is now deploying on both my iOS 12 and 14 devices. Seems it’s fixed, was something specific changed in the snapshot?

Please try the latest snapshot and let me know how that goes

Ok, good to see it’s the same issue.

I’m not sure why it may be that it seems to fail on different libGDX and iOS combinations for the 3 of us.

Here is my matrix:

	1.9.13	1.9.15-SNAPSHOT
iOS 12	Crash	Crash
iOS 14	Ok	Ok

If I understand correctly, this is @cellcrowd

	1.9.13	1.9.15-SNAPSHOT
iOS 12	Ok	Crash
iOS 14	Ok	Ok

And @yajirobe69 this is your matrix right?

	1.9.13	1.9.15-SNAPSHOT
iOS 12	Ok?	Ok
iOS 14	Ok?	Crash

To discard it’s related to the device/iPad OS I’ve tried testing on iPhone 8 and iPad (8th Gen) simulators and results are consistent
