Apple has revealed that Meta has submitted 15 interoperability requests under the Digital Markets Act in the European Union, the highest number from any country. Apple has expressed concerns that Meta's requests could compromise user security and privacy. Under the DMA, Apple must assess and potentially design solutions for interoperability requests from app developers, but warns that the integrity of iOS and iPadOS is a key consideration. The European Union has also ordered Apple to update iOS for better compatibility with competitor devices, with potential fines if Apple fails to comply with interoperability requirements.
