Would be awesome to allow uploading Xcode dsyms to sentry.io
Looks like it’s already done for you:

Hey there!
Indeed, as @YellowstoneApps mentioned, this is possible via Fastlane, which is usable in Bitrise via the integrated Fastlane step 
There also is a dedicated step for this at https://github.com/SimonRice/bitrise-step-sentry-dsym-upload but it hasn’t been added yet, see https://github.com/bitrise-io/bitrise-steplib/pull/2620
