Hi there, I'm planning to develop a simple underwater compass app for Apple Watch Ultra 2, intended for recreational scuba diving down to 40 meters. The app itself does not need depth or pressure measurements beyond 6 meters. Its primary function is compass navigation using heading data. During a dive, however, I would like the app to: remain frontmost and visible throughout the dive; use Water Lock; use an underwater-depth WKExtendedRuntimeSession; continue receiving compass heading updates; allow interaction through physical controls such as the Digital Crown and Action Button; remain operational below 6 meters, potentially down to 40 meters. I understand that the Shallow Depth and Pressure capability limits CMWaterSubmersionManager depth/pressure data to approximately 6 meters, while access to depth/pressure data down to 40 meters requires the full Submerged Depth and Pressure entitlement. My question is: If my app does not require depth/pressure measurements beyond 6 meters, is the full Submerged Depth and Pressure entitlement still required simply to keep the underwater extended runtime session, UI, compass heading updates, and physical-control interaction working below 6 meters? In other words, does the 6-meter entitlement limit apply only to depth/pressure data, or does it also limit the ability of an underwater compass app to remain operational during a scuba dive below 6 meters? Target hardware: Apple Watch Ultra 2. Thanks in advance!
