Why do you need it?

This library is an easy way to handle notDetermined, authorised, restricted and denied cases without doing it by yourself. No more need to do error handling for restricted and denied cases, create and present to user specific alerts. Of cause, it is not a silver bullet, but a good tool for your project!


  • [x] Customise or localise alerts messages via Configuration
  • [x] Automatic alert creating and presenting
  • [x] Opportunity for users to easily change permissions in Settings
  • [x] CoreLocation permission returns you completion block with user's decision
  • [x] Example project for easy understanding of framework

Supported Permission Types

  • Camera
  • Contacts
  • Events
  • Gallery
  • Location
  • MediaLibrary
  • Microphone
  • Reminder
  • Siri
  • SpeechRecognition

Installation with CocoaPods

ios-permissions-service is available through CocoaPods and Carthage


To install it, simply add one or several lines to your Podfile like this:

  pod "PermissionsService/Location"
  pod "PermissionsService/Camera"

Full list of available permissions you can found here.

If you'll need, there is still a versions written on Swift 3/4 which you can find in separate branches

Now you need to run pod update command from you project folder and that's it!


  1. Add the following line to your Cartfile:
  github "lemberg/ios-permissions-service"

If you want to use a specific branch with another Swift version you can add branch name:

github "lemberg/ios-permissions-service" "swift4"
  1. Run carthage update --platform iOS command from you project folder.

  2. Find the Carthage/Build folder, which is in your project folder. Drag and drop PermissionsService.framework file, to the Linked Frameworks and Libraries section in General settings tab of your project.

  3. Do to Build Phases settings tab. Click the “+” icon and choose New Run Script Phase if not exist. Add the following line to your script

  /usr/local/bin/carthage copy-frameworks
  1. Add the framework's paths under Input Files:
  1. Add the framework's paths to the Output Files:

More info about using and configuring Carthage you can find here.


There is an important note about installing, because of Apple's policy. Due to this policy regarding permission access, binaries may be rejected due to a perceived attempt to access privacy-sensitive data without a usage key, and then further rejected for not actually requesting permissions. This error will be when you'll try uploading to itunesconnect.

But there is a solutuion. You need to provide custom build flags before building the dynamic framework to only compile with permissions you request.

  1. Go to your project root directory and add xcconfig file named PermissionConfiguration.xcconfig. Example of such file you can find here.

  2. Comment lines which you don't want to use like this:


Here you can see an example of using only Camera permission. Contacts permission will be unavailable.

  1. Now you can run carthage update --platform iOS to compile framework.

If you'll need to change available permissions, go to PermissionConfiguration.xcconfig file and modify it. Then update the framework again.

How To Use

  1. Configure your project in all ways needed for chosen permission type. For example, in a case of a gallery, add a specific key to your .plist file.

  2. Implement Permissible protocol in your class. If it's not a UIVIewController class you should implement showAlert(_:) method, but if it is - there is a default implementation and you can leave it empty.

  3. Add Permission<T: PermissionService> object with a type you needed and use prepare(_:) method for request permission and presenting alert to the user.

  Permission<Gallery>.prepare(for: self, callback: { (granted) in
      if granted {
          //present library
      } else {
          //perform specific functions 

This case if show a simple variant of use with default permission settings.

Be aware that Calendar permission service named Events.

  1. Enjoy!


This library gives you an opportunity to do some customising or configurations if you need it.

Configurate messages

You can add custom alerts messages for denied and restricted cases by creating new struct which conform to ServiceMessages protocol.

struct CameraMessages: ServiceMessages {
    let deniedTitle = "Access denied"
    let deniedMessage = "You can enable access to camera in Privacy Settings"
    let restrictedTitle = "Access restricted"
    let restrictedMessage = "Access to camera is restricted"

To use your custom messages you need to use DefaultConfiguration class. Let's init it!

   let config = DefaultConfiguration(with: CameraMessages())

And now put it in prepare(_:) method, like this:

  Permission<Camera>.prepare(for: self, with: config) { (granted) in
     if granted {
     } else {


Location permission types

As you can know, you can request two types of user location permission: WhenInUse and Always. For choosing it you need to use configurations too. Class LocationConfiguration is a subclass of DefaultConfiguration and have the same way to use.

You can init it only with type

      let config = LocationConfiguration(.always)

Or you can use it with your messages

     let config = LocationConfiguration(.always, with: CustomLocationMessages())

And then simply put it in your prepare(_:) method as you already did with DefaultConfiguration.

  Permission<Location>.prepare(for: self, with: config) { (granted) in
     if granted {
     } else {
