@benjohnde & @tknoelle As far as I understood you two can approve and merge a pullrequest. It would be very cool if you could review it, merge it back and release a new version which can be used with xCode 14.x.

One of the changes is breaking target "OS X". See other comments

The osx target and its unit tests are passing, now that I updated the deployment target to 10.15. Also I updated the README to indicate the new base level.

Appreciate your work :)

I added some new comments in Pullrequest.

@kenstir Are you able to make the change to the "s.ios.deployment_target" and "s.osx.deployment_target" values in the "ZXingObjC.podspec" file as requested by @KBEMobisys in the pull request here?

I will do it! Sorry for letting this drag on.

self check: pass

All the PR comments are addressed and I'm ready for a rereview.

Hey, these changes are exactly what I'm waiting for! When can I expect to bump deployment target to keep Xcode 14 happy?

@adil-hussain-84 Could you review the pull request again? And are you able to merge it or who can do this??
Would be great to finalize this soon :)

@KBEMobisys: Sadly I don't have write access 🙁 I'm hoping one of the individuals listed in the Kudos section of the project's README file (@cwalcott and/or @neacao perhaps) can review the pull request and merge it in 🙏

@benjohnde @tknoelle You are members of zxingify. Could you review and merge this PR?

We would love to see a new release with this change, so zxingify is compatible to Xcode 14.3 and above.

Sry for the delay, I can merge it tomorrow and also prepare a cocoapods release.

Thank you so much @benjohnde for merging in the pull request and performing the release 🙏 We were starting to fear the worst that we'd have to fork this repository and maintain the fork.
