realm/realm-swift v10.28.2 on GitHub

Using seedFilePath threw an exception if the Realm file being opened already existed (#7840, since v10.26.0).
The intialSubscriptions callback was invoked every time a Realm was opened regardless of the value of rerunOnOpen and if the Realm was already open on another thread (since v10.28.0).
Allow using RLMSupport.Swift from RealmSwift's Cocoapods (#6886).
Fix a UBSan failure when mapping encrypted pages. Fixing this did not change the resulting assembly, so there were probably no functional problems resulting from this (since v5.0.0).
Improved performance of sync clients during integration of changesets with many small strings (totalling > 1024 bytes per changeset) on iOS 14, and devices which have restrictive or fragmented memory. (Core #5614)
Fix a data race when opening a flexible sync Realm (since v10.28.0).
Add a missing backlink removal when assigning null or a non-link value to an AnyRealmValue property which previously linked to an object. This could have resulted in "key not found" exceptions or assertion failures such as mixed.hpp:165: [realm-core-12.1.0] Assertion failed: m_type when removing the destination link object. (Core #5574, since the introduction of AnyRealmValue in v10.8.0)
