React-native-background-geolocation: Compatibility iOS 11

[robmoorman]

Your Environment

• Plugin version: 2.8.1
• Platform: iOS
• OS version: 11.0 (Beta 2)
• Device manufacturer / model: iPhone 7 (or any other model)

Expected Behavior

While calling the startGeofences method permissions are asked.
After confirming permissions the module starts working.

Actual Behavior

Nothing happens. No permissions for geolocation and probably therefore also no working module.

Steps to Reproduce

1. Install latest Xcode-beta (beta 2 with iOS 11.0 beta 2)
2. Run any application with this module

[christocracy]

In your .plist, do you have Location Always Usage Description in addition to Location When In Use Usage Description? iOS 11 enforces apps to offer both now.

[christocracy]

[robmoorman]

Ok cool will give it a try

[christocracy]

Blood hell: iOS 11 has changed the key name NSLocationAlwaysUsageDescription -> NSLocationAlwaysAndWhenInUseUsageDescription

2017-07-03 10:42:12.066579-0400 BG Geo 2[2528:151833] This app has attempted to access 
privacy-sensitive data without a usage description. 

The app's Info.plist must contain both NSLocationAlwaysAndWhenInUseUsageDescription 
and NSLocationWhenInUseUsageDescription keys with string values explaining to the user 
how the app uses this data

[christocracy]

TSLocationManager needs a small fix too, to request this new permission.

However, XCode 9 beta 2 is crashing constantly on me. I have to wait until they release a new beta to fix this.

[robmoorman]

Ok it also seems to prevent older iOS versions having not the the new plist description to support both NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription

[christocracy]

Correct. I won't be able to fix this for iOS 11 until a new beta of XCode 9 is released.

[robmoorman]

Hi @christocracy I see beta 3 is released yesterday, hopefully this fixes your Xcode issues https://developer.apple.com/download/

[christocracy]

Thanks

[christocracy]

Still crashes for me.

[christocracy]

Ok, I powered through the crashes enough to push a fix to the premium version.

XCode still crashes all the time but sometimes it stays up long enough to get some work done.

[jcity]

Asking this here but lmk if you'd rather have a separate issue.

Have you discovered a way to get around having the blue bar appear on iOS but still get location updates in the background?

Also, just to make sure I'm following correctly, the next version (presumably 2.9) will be _required_ for compatibility with iOS 11. Correct?

[christocracy]

To get rid of blue bar, user must accept location request "Always". You'll want to configure the plugin with locationAuthorizationRequest: "Always"

[christocracy]

2.9 will be compatible with iOS 11

[jcity]

Will configuring with locationAuthorizationRequest: "Always" hide the blue bar on iOS 11 too?

[christocracy]

The blue bar appears only when the user has selected "When In Use" when the location permission is requested.

This plugin is designed primarily for "Always" authorization. The plugin's behaviour is severely weakened when used with "When In Use".

This is a long-term tracking plugin, primarily designed for fleet-tracking applications where the end-user knows exactly what's going on.

[JAStanton]

The blue bar appears only when the user has selected "When In Use" when the location permission is requested.

This is true for iOS 10 but not iOS 11:

ANY time a background app uses your location in iOS 11 the blue bar is on.

[christocracy]

I haven't been able to get XCode 9.beta to work reliably on my machine without crashing.

Seems the blue bar will be permanent then. Hopefully that doesn't apply to significant-changes and geofences.

[christocracy]

I personally have no issue with the blue bar. This plugin is primarily designed for fleet-tracking app where the user knows exactly what the app is doing.

The user should know when an app is aggressively tracking their location.

[christocracy]

Yes: blue bar will only appear when plugin is in "moving" state. It will be off when plugin is in stationary-state.

It will not appear from geofence monitoring or significant-changes.

It will only appear when CLLocationManager#startUpdatingLocation. That's reasonable.

[aaronbuchanan]

any update on this? Do we just need to add these keys to info.plist or will we need to update this lib?

[christocracy]

You just need to add new plist key NSAlwaysAndWhenInUseUsageDescription.

And install plugin from master for now.

I’m building with latest Xcode on my iPhone 6s @ iOS 11. Everything is normal

[pencilcheck]

I did everything (or at least I assumed)

1. Point to master in package.json
2. Add plist key
3. Rerun pod install for podfile
4. Upgrade the extension file for the new background-fetch syntax
5. Turn on debug
6. Running on xcode 9, iOS 11 simulator, turned on location in the debug menu

But it doesn't work, it is doing nothing. Below is the log:

[christocracy]

@pencilcheck So you have the key Privacy - Location Always and When In Use Usage Description in your .plist?

[pencilcheck]

I got it to work, thanks to your screenshot, turns out I need more than Privacy - Location Always and When In Use Usage Description, and Privacy - Location Always Usage Description, Privacy - Motion Usage Description in my .plist

[christocracy]

Yes, I discovered this myself today.
