Release mode retrieveCalendars in iOS

[eliseyOzerov]

Basically the same issue as for the Android where the retrieveCalendars function doesn't work in release mode. I fixed it on Android by using the suggestion in #99 and the package documentation, but what do I have to do to make it work on iOS too?

Will need to investigate, but meanwhile have you tried the iOS integration in the readme file?

iOS Integration

For iOS 10 support, you'll need to modify the Info.plist to add the following key/value pair

<key>NSCalendarsUsageDescription</key>
<string>INSERT_REASON_HERE</string>

Note that on iOS, this is a Swift plugin. There is a known issue being tracked here by the Flutter team, where adding a plugin developed in Swift to an Objective-C project causes problems. If you run into such issues, please look at the suggested workarounds there.

[eliseyOzerov]

Yes, this has already been done and the project is written in Swift.

Hi guys, is there an update to this issue? I have a feature hung up on a project regarding the calendar with no solution to date.

Just tried with my personal iPhone using flutter run --release -d "[MY_PHONE_NAME]" and I was able to retrieve calendars, events, etc.

It could be possible that the calendar permission has been denied somehow in the device you're testing on? Maybe try the above command with a different device?

Is this working fine in IOS release mode. It is working fine in debug mode in all IOS devices that I had tested.

@eliseyOzerov / @Ananthan1996 are you able to run the sample app in release mode and verify you're able to access the calendars ok?
