Currently on Xcode 26.0 beta 7 (17A5305k), macOS 15.6.1 (24G90) For our main Phonepe app (https://apps.apple.com/in/app/phonepe-secure-payments-app/id1170055821) dSYM size went from 281 MB (xcode-16) to 584 MB (xcode-26) Tried replicating the issue for Alamofire Example app (https://github.com/Alamofire/Alamofire), there as well dSYM size went from 2.7 MB (xcode-16) to 5.8 MB (xcode-26). All Build were all release builds

dSYM size became thrice for builds generated via xcode 26 compared to xcode 16. These are all release builds.
