* Fix many version checks to be based on Xcode version instead of iOS version.
* Added/fixed a few expected values according to platform version to match behavior in older macOS versions.
* Adjust ever changing AddressFormatingTest for iOS 10, which does
not output the country;
* Adjust Contact's ICNKeyDescriptor internal check;
* CLBeaconRegion.ProximityUuid does not return the original instance
anymore, but a different one with the same uuid;
* Add a small delta for Vector3 comparison in ModelIO tests;
* Adjust MapKit tests for pin color change and MapRect corner case;
* SecKeyTest with corner cases now pass (they failed before);
* SecPolicyIdentifier.AppleIDValidation does not report the OID it's
created from (migration?)
Note: some might be bugs that Apple will fix in later seeds
