Imperial Units in iOS UI

[jpmens]

As submitted in https://github.com/owntracks/android/issues/1573 and discussed in https://github.com/owntracks/android/discussions/1571, there is an enhancement idea to have the UI present data in Imperial units? Feet, miles, mph, etc.

I'd assume a toggle in settings which defaults to metric.

In favor of feature parity between the apps, I link this here.

Unfortunately this does not work (only for Apple Maps). Need to change Region in "Settings/General/Language&Region" ~~In iOS, the user can use "Settings/General/Language&Region/Measurement System" to select the system. <img width=github.com/owntracks/ios/assets/4027289/d9f924f9-8536-463c-9141-d29f5cca1ec3">~~

Will use

• feet (ft) for altitudes and accuracy
• miles per hour (mph) for speed
• yards (yd) for short distances (less than a mile)
• miles (mi) for long distances

no change to

• heading in degrees (°)

• barometric pressure in kiloPascal (kPA)

• radius of circular regions in meters (m)

• other settings typically in meters (m)

Looks good to me!

Using Apple Foundation's NSMeasurementFormatter now:

... Representations of measurements are reduced and converted into a more convenient unit, when possible. For example, a quantity of 12000 meters would be represented as 12 kilometers.

Use Region to change settings! Changes to Measurement System affect Apple Maps only!
