unable to read property list from file, Info.plist issue when I use Mapbox sdk in my app

Question

im facing an issue in one of my flutter apps. Im was using MapBox-SDK plugin but when I tested the app on IOS, it asked me to update my Mapbox-sdk to some version (which I did using pop install command). Now after everything, I am facing new errors in my info.plist file. I forgot to take a backup of my old info.plist file. Anyways, the new info.plist is:

<plist version="1.0">
<dict>
<string>YES</string>
<key>io.flutter.embedded_views_preview</key>
<true/>
<key>MGLMapboxAccessToken</key>
<string>Mapbox-key-not-visible</string>
<true/>
<key>NSLocationWhenInUseUsageDescription</key>
<key>NSLocationAlwaysUsageDescription</key>

    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
</dict>
</plist

the error im facing while building up the app is:

You don't have value for NSLocationWhenInUseUsageDescription and I guess this is the problem – Sarmatia

Answer 1

The error error: unable to read property list from file: Info.plist is usually caused by missing config on the plist file. As previously mentioned in the comments, you need to have a value set on NSLocationWhenInUseUsageDescription. More details are explained in the package's docs.

<key>NSLocationWhenInUseUsageDescription</key>
<string>[Your explanation here]</string>

In my case, it was because the Info.plist file was poorly formatted. It hasn't to do with XML format, because when I tried to find if that file was correctly formatted according to XML rules, it was ok, but when I tried to open the .plist file as a property list, I realized Xcode couldn't read it, so I added my keys using the property list utility, not the "code view".

I have been facing the same problem with a newly imported Flutter project. After some debugging, it seems like the issue was caused by a corrupt GoogleService-Info.plist file! Dunno why and how it was corrupted, because I have newly imported and existing project.

To solve this problem, you can follow those steps;

Open your project in XCode delete the existing GoogleService-Info.plist file download the original one from Firebase then reimport/re-copy this file into your project When this is done, run flutter clean then try running it in iOS Simulator

This worked for me, hope it solves your problem too.

I solved this issue by including <string/> after each <key>...</key> like this :

<key>NSPhotoLibraryUsageDescription</key>
<string /> 

<key>NSCameraUsageDescription</key>
<string /> 

<key>NSMicrophoneUsageDescription</key>
<string />

Answer 5

if you add the keys without any value, it will cause this issue.

Step 1:

Open as source code

Step 2:

check if any keys like this without any values. Remove this key and save

<key></key>

Step 3:

Right click info plist file -> Open as Property List

Answer 6

Apparently I have 2 values string for 1 key. Here's example from my incorrect Info.plist:

<key>CFBundleURLName</key>
<string>mydomain</string>
<string>com.mydomain.name</string>

What I do to resolve this is to remove one of the value that doesn't match the key so it would be like this:

<key>CFBundleURLName</key>
<string>com.mydomain.name</string>
