+**`validate_podspec` was bypassed!**
+
+As of Xcode 14.3, libraries with deployment target below iOS 11 (iOS 12 in Xcode 15) fail to build out of the box.
+The reason is a missing file, `/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a`, more info [here](https://stackoverflow.com/questions/75574268/missing-file-libarclite-iphoneos-a-xcode-14-3).
+
+Client apps can work around this with a post install hook that updates the dependency deployment target, but libraries do not have this option.
+
+Our old Alamofire dependency targets iOS 8.0, making the validation build fail.
+
+In the interest of using up to date CI (i.e. not waste time downloading old images) we bypass validation until either we are able to drop or upgraed Alamofire, or find a workaround.
